PackLib is about to expose its product builder as a swift-dependencies client so the dev commands and tests can substitute it. The package is already part of the graph through XToolSupport; this only adds the Dependencies product to the PackLib target. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Introduce the types the macOS route builds on, without enabling it: - TargetTriple and ResolvedTarget parse the selected triple and resolve the deployment version from the triple, the schema or the package's declared platforms, rejecting versions below the platform minimum. - BundleLayout describes where executables, frameworks, resources and nested products live in iOS and macOS bundles. - xtool.yml version 2 adds target, deploymentTarget, product sources, resourceCopies and nestedProducts, and accepts ICNS icons. Version 1 configurations reject the new keys. - DeferredSigningManifest records what a downstream signer needs. - iOS compilation moves out of Packer into ProductBuilder, exposed as the ProductBuilderClient dependency. macOS targets, version 2 product sources and resource destinations still fail with "not implemented yet" errors.
Teach ProductBuilder to compile the products a plan selects for any supported triple: - Each product is built with its own `swift build --product` call and located through `--show-bin-path`; builds pass the versioned target triple, including for iOS. - Products with a direct `.executable` source are built as-is; other products still go through the generated wrapper package, whose manifest now quotes paths as Swift string literals. - BuildSettings rejects triples it does not recognise, and rejects Debug macOS builds on Linux hosts. Planner and Packer still refuse macOS targets, so `xtool dev` cannot reach this path yet.
Plan macOS and version 2 configurations instead of rejecting them: - Package inspection moves behind the PackageInspectionClient dependency and also reads `swift package dump-package`, so dependency platform conditions decide which libraries and resource bundles a product pulls in for the selected platform. - Products may name an explicit or prebuilt source, may be qualified by package, and may declare nested products (XPC services, helpers) and resourceCopies. Plugin targets are skipped and duplicate resource bundles are planned once. - When an Info.plist overrides CFBundleIdentifier, the plan's bundle ID follows it. - Extensions are planned sequentially. Selecting the target through xtool.yml's `target` key is still rejected here; the dev command learns to honour it in a later commit.
Replace Packer's concurrent iOS copy step with BundleAssembler, which assembles iOS and macOS bundles, including nested app extensions, XPC services and helpers, from the plan and BundleLayout: - Every destination is computed and checked for collisions before anything is written. - Raw asset catalogs, XIBs and storyboards are rejected; supply compiled or prepared resources instead. - An existing CFBundleIconFile in the product's Info.plist is kept. - Resource and icon paths resolve against the package path, and output goes to `<package>/xtool`. - SwiftPM resource bundles are linked next to the executable so the generated `Bundle.module` accessor finds them. Packer no longer rejects macOS targets.
Route `xtool dev build` for macOS targets: - `--defer-signing` builds and assembles the app, then writes `<App>.signing.json` and a `<App>.signing-inputs/` directory with each product's entitlements for a downstream Mac signer. macOS builds without it are rejected, as are `--sign`, IPA output, `dev run` and Xcode project generation for macOS. - The route is validated before authentication, SDK setup or packing. - The selected target now comes from `--triple`, then xtool.yml's `target`, then the iOS default, for build, run and generate-xcode-project; the planner stops rejecting a configured target. - Command effects (schema loading, SDK setup, packing, Xcode generation, running) move behind the DevCommandClient dependency.
Check what the linker produced before a bundle is assembled: - Built products, prebuilt products and binary targets are parsed as Mach-O and rejected when their file type, architecture or platform does not match the plan. - Each product gets the runpath search paths its bundle location needs. Helpers search both the app's Contents/Frameworks and their own Frameworks directory, so libraries assembled next to a helper load. - `.prebuilt` product sources are accepted. - macOS links pass `-platform_version macos <deployment> <sdk>` from the SDK's SDKSettings.json, because LLD on Linux otherwise records the deployment version as the SDK version.
Make editor configuration follow the same target resolution as builds: - `xtool dev build-server` resolves the target from `--triple`, xtool.yml and the package's platforms through the planner. - With Swift 6.4 and later, `.bsp/xtool.json` launches the build server with the selected `--triple`. Earlier toolchains get a `.sourcekit-lsp/config.json` with the Swift SDK and the versioned compiler triple. - Generated files are refreshed or migrated only when they match xtool's complete generated content; customised files are kept. - Document target selection in Control.md. The new tests build iOS BuildSettings, which on Linux need an installed Darwin SDK, so the integration script now installs the SDK before running `swift test`.
Helpers share the Contents/Helpers location, so two helpers that depend on the same library or resource bundle generated identical copy operations and failed with a destination collision. Merge identical generated operations across helpers. A dependency repeated within one helper, or an explicit copy that collides with a generated one, is still rejected.
codesign rejects anything outside Contents/ in a macOS bundle, so the resource-bundle links at the bundle root made every app with a SwiftPM resource target unsignable. Keep one copy of each resource bundle in Contents/Resources instead: - For macOS products with resource bundles, ProductBuilder rebuilds the product with a compiler VFS overlay that adapts SwiftPM's generated `Bundle.module` accessor to look in `Bundle.main.resourceURL`, falling back to the directory-based lookup. Package sources are not edited. Only Swift resource targets are supported. - Helpers place their resources in the app's Contents/Resources and keep a relative link in Contents/Helpers for the executable-directory lookup. - Identical generated operations are now merged across all products, not only helpers. - Prebuilt macOS products that need SwiftPM resource bundles are rejected, since their accessors cannot be adapted.
Add MacOS.md describing the macOS route (target selection, bundle assembly, the deferred signing handoff, tests and boundaries) and extend Configuration.md with the version 2 keys, helper and resource destinations, and how resource relocation is verified.
SwiftPM copies a static XCFramework slice into the bin directory under the slice's LibraryPath, which need not be `lib<target>.a`. Read the extracted XCFramework's Info.plist, pick the library for the planned platform, variant and architecture, and use its LibraryPath when validating and assembling binary targets. Framework slices and targets without an extracted XCFramework keep the previous lookup.
PackLib starts hashing build artifacts for the verified macOS build handoff. swift-crypto is already a package dependency used by XKit; this adds its Crypto product to the PackLib target. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
XToolSupport and the xtool executable named SwiftyMobileDevice by bare product name, while XKit already spells out the package. Use the explicit `.product(name:package:)` form everywhere. No dependency or version changes. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
- `xtool dev run` builds and launches a macOS app, forwarding arguments after `--` and exiting with the app's status (128+n when it is killed by signal n). `--app <path>` launches an existing .app without building, and `--triple` overrides the configured target. - `xtool dev build --defer-signing` also writes `<App>.artifact.json`, a SHA-256 inventory of the bundle and its signing inputs, and removes a stale `<App>.signing-inputs/` before writing new ones. `xtool dev verify` checks a handoff against that inventory. - MacBundleAudit walks the bundle's Mach-O load commands and rejects dependencies that resolve neither inside the bundle nor to a system library. - `--swift-sdks-path` and `--scratch-path` select a prepared Swift SDK directory and a separate SwiftPM scratch directory for macOS builds. - Add a Bats suite for the macOS CLI and document running apps.
Add `xtool dev sign`, which signs a copy of a verified build handoff into a new output directory: - Modes: ad-hoc, development and developer-id. Certificate modes take an explicit identity SHA-1; `--dry-run` prints the plan and also works on Linux. - The copy is checked against the handoff inventory before signing. Nested code is signed inside-out with `--force` and without `--deep`; developer-id uses the hardened runtime and a secure timestamp. Each product gets its own entitlements, also embedded in DER form. - The signed app is published by renaming it from a private staging directory next to the output. - `xtool dev verify --signed` runs `codesign --verify --strict` on every code node and checks the certificate category, team ID and effective entitlements, then writes a receipt. The handoff changes with it: entitlement inputs are stored under their content hash instead of clearing the inputs directory, MacBundleAudit treats extra executables in Contents/MacOS as their own signing nodes and resolves frameworks through their Info.plist, and MacArtifact validates each product's canonical path, layout and package type.
Add `xtool dev notarize` with submit, status, resume, log, staple and verify actions for a signed developer-id app: - submit zips the app with `ditto` into a release directory and sends it with `notarytool` using a keychain profile. - Every step appends a numbered receipt that records the hashes of the uploaded archive and the signing receipt. Each resumed action checks them before contacting Apple, and an exclusive lock prevents concurrent runs on one directory. - resume waits for a known submission. Stapling requires an Accepted result whose log matches the submission ID and the archive hash. It staples a copy, validates it and publishes it by renaming. - Credentials stay in the keychain; only the profile name is passed or recorded. Document notarization in the README.
SwiftPM only matches an installed Swift SDK by its unversioned triple, so `--triple arm64-apple-macosx16.0` could not use the Darwin SDK on Linux. Write a single-target destination (schema 4.0) derived from the installed SDK into `.build/xtool-sdk` and pass it with `--destination`, so SwiftPM applies the requested deployment version. Make relative SDK paths absolute, keep an absolute swiftResourcesPath, and put the toolset's rootPath on PATH so dsymutil is found.
MachOBinary.validate only recognised a static archive by the `!<arch>` magic at the start of the file. A universal binary whose slices are static archives, the usual layout of a `macos-arm64_x86_64` XCFramework slice, was validated as a dynamic library and failed with "Wrong Mach-O file type; expected 6". Mark slices read from archive members and decide per slice whether an object file or a dynamic library is expected. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
MacBundleAudit accepted an @rpath dependency as soon as any rpath candidate was a system path. swiftc adds LC_RPATH /usr/lib/swift to every macOS executable, so every @rpath dependency of a Swift app was treated as a system library and skipped: a framework missing from Contents/Frameworks passed `dev build` and `dev verify` and then failed in dyld at launch. Require an @rpath dependency to resolve inside the bundle. Only Swift's back-deployment libraries (`@rpath/libswift*`) may resolve to a system rpath, since they ship with the OS.

xtool.yml's legacy `resources` list was copied to the bundle root on every platform. On macOS the bundle root is outside the code signature's resource seal, so codesign rejects the app, and `Bundle.main` does not look there either. Copy legacy resources to each product's resources directory instead: unchanged on iOS (the bundle root), Contents/Resources on macOS.

SwiftPM extracts remote and zipped binary targets into its artifacts directory, but leaves a local `.binaryTarget(path: "X.xcframework")` in place and only copies the slice's library into the bin directory. The static-archive lookup only searched the artifacts directory, so a local static XCFramework whose LibraryPath is not `lib<target>.a` failed with "Missing binary target". Record the absolute path of local XCFrameworks from `swift package describe` on the planned binary target, and read that Info.plist first. Checked against a real local static XCFramework with `xtool dev build --defer-signing`: it fails before this change and builds and runs after it.

`dev run` captures app arguments with `.captureForPassthrough`, which also captures unknown options and words. Because `run` is the default `dev` subcommand, a typo stopped being a parse error: `xtool dev run --cofiguration release` built Debug and passed the typo to the app, and `xtool dev biuld` ran the app. Only accept captured arguments after `--`. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
The SwiftPM backend compiles Darwin targets for each package's declared platform minimum and ignores the version in `--triple`. For a package without `platforms`, xtool planned macOS 15.0 and the linker recorded `minos 15.0` (via `-platform_version`), but Swift compiled against the SwiftPM default, so macOS 15-only APIs such as `Mutex` failed availability checking. Pass `-target <compiler triple>` to the Swift, C and C++ compilers through the target-only toolset, for direct executables and for the generated wrapper package. The native fixture no longer declares platforms and uses `Mutex` in both build paths. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Bundle assembly rejects raw asset catalogs, iconsets, storyboards and XIBs in every copied input. SwiftPM's native build copies these into resource bundles uncompiled, so an iOS app depending on a package with an asset catalog, which packaged on main, failed to assemble. Copy SwiftPM resource bundles as built on iOS again. User-supplied inputs on every platform, and resource bundles on macOS, are still rejected as documented. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
ResolvedTarget used a package's declared platform version as the deployment target and then rejected it when it was below xtool's platform minimum. A package declaring `.iOS(.v12)`, which built on main with no way to override it in a version 1 xtool.yml, failed with "Deployment target 12.0 is below required minimum 13.0". Raise a package minimum below the platform minimum to that minimum. An explicit triple or schema version below a minimum is still rejected. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
`xtool dev build-server` ran the full planner on every start (`swift package show-dependencies`, `describe` and `dump-package` on the main `.build`), bypassing the server's own `--disable-automatic-resolution` and `--experimental-skip-acquiring-lock`. A broken manifest, a missing Info.plist or an ambiguous product kept the editor's build server from starting, and starting it could resolve over the network or wait on the `.build` lock. Without xtool.yml it also printed a warning to stdout, ahead of the build server protocol stream. The generated `.bsp/xtool.json` now pins the planned compiler triple (for example `arm64-apple-macosx15.0`), and the server resolves its target from that triple and xtool.yml alone. Configurations generated with an unversioned triple are still recognised and refreshed. The missing-xtool.yml warning goes to stderr.

Each direct product's toolset carried its rpaths, extension entry point and SDK `-platform_version` as Swift compiler options. Products share one scratch path, so the differing compile command lines made SwiftPM recompile every module for each product. Put those options in the toolset's `linker` section and keep only the deployment target in the compiler sections, so compile commands are identical across products. Omit empty toolset entries, which SwiftPM rejects. This alone does not remove recompilation for macOS products with resource bundles; the resource accessor overlay is handled next. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Each macOS product with SwiftPM resource bundles was built, then built again with its own `-vfsoverlay` for the adapted `Bundle.module` accessor. The overlay flag differed between products and between the two builds of a product, so every module was recompiled twice per product. Build all products first, then write one overlay covering the generated accessors of every built product and rebuild each product with that same overlay. In the relocation fixture (app, XPC service and helper sharing a resource library), the shared resource module now compiles twice per configuration instead of six times. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
DevRunCommand captured app arguments with .captureForPassthrough and
rejected anything not preceded by `--` in validate(). The capture also
swallowed --help, so `xtool dev run --help` failed with "Unknown
argument '--help'" (exit 64).
Collect app arguments with .postTerminator instead. ArgumentParser now
handles help, reports typos itself ("Did you mean '--configuration'?"),
and only values after `--` reach the app, so validate() and the
dropFirst() are gone.

macOSRunAndXcodeRejectBeforeEffects relied on MacRunClient's implicit testValue (isMacOS: false) to make requireHost() throw. Resolving an implicit test value goes through swift-dependencies' CachedValues, which calls swift-issue-reporting's TestContext.current. With the swift.org Swift 6.4.0 macOS toolchain (Swift Testing library 1902; swift-dependencies 1.17.1 resolves swift-issue-reporting 2.1.2) that call faults with SIGBUS and takes down the whole test process. Xcode 27's Swift 6.4 (swiftlang-6.4.0.34.1, Swift Testing library 2084), which CI uses, does not crash. Reported as pointfreeco/swift-dependencies#474. Override macRunClient with .testValue so the simulated host is explicit and no implicit lookup happens. Behaviour under test is unchanged.

macos.bats only ran in the integration job, inside Linux Docker, so the CLI was never exercised end to end on a Mac: the implicit Darwin SDK, the toolset -target, and verify on the host that builds. Run the same suite in build-macos after the unit tests, reusing its xtool build. bats-core, bats-support and bats-assert are cloned at pinned release tags; llvm-objdump comes from the selected Xcode via xcrun.

MacOS.md was written before `dev sign` and `dev notarize` landed and still listed notarization and Developer ID signing as out of scope. Point the guide at both commands and narrow the boundary to what remains excluded: certificate creation, identity selection and provisioning-dependent entitlements.

48441b6 passed `-target <planned triple>` to the Swift, C and C++ compilers through the SwiftPM toolset. A toolset applies to every module in the build graph, so dependencies were compiled for the app's deployment target instead of their own platform minimum. That breaks packages whose backports are obsoleted on newer releases: building a macOS 15.0 app that depends on swift-perception failed in PerceptionCore with "'Bindable' is unavailable in macOS" on its own conformance extensions. `swift build` and Xcode compile each package for its own declared platforms. Drop the compiler sections; the toolset now carries only the per-product linker options. Binaries still record the planned deployment target through `-platform_version`, so `minos` is unchanged. A package whose own code needs newer APIs declares `platforms`, as it must for `swift build`. The native fixture now declares macOS 10.15 and ships a swift-perception-style backport obsoleted in macOS 14; it fails to compile with the previous toolset and passes now. A swift-perception app built with `xtool dev build --configuration debug` fails at 344c06c (8 unavailability errors) and succeeds here with `minos 15.0`.

macOS assembly rejected any SwiftPM resource bundle containing a raw asset catalog, iconset, storyboard or XIB. SwiftPM's native build copies those into resource bundles uncompiled, so an app could not be packaged whenever a dependency shipped one: CodexBar fails on Vortex's Assets.xcassets, a bundle the app author cannot change. Copy SwiftPM resource bundles as built on macOS too, matching iOS (6f7d68e) and `swift build`. Inputs supplied through xtool.yml are still rejected. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
9f36e62 made every build pass `--triple <planned compiler triple>`, which always carries a version. SwiftBuild turns a versioned triple into the deployment target of every package, so with Swift 6.4, where iOS builds default to SwiftBuild, dependencies compiled for the app's minimum instead of their own. A dependency with backports obsoleted at that release then fails to compile, as e7a5f52 describes for the SwiftPM backend. Keep the triple selected at initialization, as on main. The wrapper package's `platforms` already carries the plan's deployment target. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
The 15.0 floor had no technical basis and raised packages that declare an older minimum: CodexBar (14.0) then compiled at 15.0, where APIs it uses are unavailable. AeroSpace (13.0) and CodexBar (14.0) build at their declared minimums with this floor, and their binaries record those as minos. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
1f58f77 keeps the unversioned triple for SwiftBuild so packages compile at their own minimums; the editor's build server inherits that. The test still expected the versioned triple and failed on Swift 6.4, where SwiftBuild is selected. The xtool build-server command keeps pinning the versioned triple. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Products with macOS SwiftPM resource bundles were built twice per invocation: once plainly, then again with `-vfsoverlay` for the adapted `Bundle.module` accessor. The first pass of every invocation undid the flags of the previous invocation's last pass, so even a no-op rebuild recompiled every module twice. Pass the overlay from the first build on. Its path never changes, and before building it covers the accessors the previous build generated. After the build, any accessor whose adaptation changed (all of them on a clean build) is touched and the products are built once more with the same flags, which recompiles only those modules and their dependents. The wrapper package and toolsets are now written only when their contents change, so unchanged builds do not relink either. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
A clean build of a macOS app with SwiftPM resource bundles compiled every module that owns a bundle, and every module depending on one, twice: the overlay adapts the generated `Bundle.module` accessors, but SwiftPM only writes them while planning the first build. CodexBar's clean release build took 778 s, against 421 s for `swift build`; the second pass recompiled the app module alone for 340 s. When the overlay does not cover every resource bundle, run `swift build --print-manifest-job-graph` with the same arguments first. It plans the build, which writes the accessors, and compiles nothing. The overlay then adapts them before the first compile, and the build runs once. The post-build pass stays as a fallback, and now also covers an accessor the build compiled without adaptation whose adapted copy was unchanged. That happened when `.build` was removed but `xtool/.xtool-tmp` was not: the build compiled SwiftPM's own accessor, found no changed copy, and shipped a binary that looks for resources at the build path.

- Around line 31-34: Update the output handoff description in the MacOS
documentation to include the product’s .artifact.json alongside the app, signing
manifest, and optional signing-inputs directory; change “Transfer all three
together” to indicate all listed artifacts must be transferred together.

directory, so copies created by withPackagePath keep cache writes out of
dependency directories.
Review comments at @Sources/XToolSupport/MacRunOperation.swift:
- Around line 59-65: Update run(bundle:arguments:) to derive the audit target
from the existing app rather than ResolvedTarget.resolve’s build-time minimum
policy or the host architecture alone. Add a PackLib ResolvedTarget entry point
that validates the version syntax without enforcing the build minimum, then
inspect the main executable’s slices and prefer the host architecture, falling
back to x86_64 on arm64 hosts. Use the bundle’s LSMinimumSystemVersion, with an
appropriate existing-app default, when creating the target.

MacOS.md named the app, the signing manifest and the signing inputs as the files to transfer, but `dev verify` and `dev sign` also read `<product>.artifact.json`. Following the page left it behind and both commands failed on the Mac. The README already lists all four. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
On Linux, every SwiftPM invocation for a macOS target writes its generated destination to `.build/xtool-sdk` under `packagePath`. The planner inspects dependencies through `withPackagePath(node.path)`, so each `describe` and `dump-package` wrote that file into the dependency: into `.build/checkouts/<name>` for remote packages, and into the user's own source tree for `.package(path:)` dependencies. Capture the cache directory from the root package when the settings are created, so rebased copies keep writing there. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
`dev run --app` built its audit target with `ResolvedTarget.resolve`, from the host architecture and `LSMinimumSystemVersion`. That applied xtool's build policy to apps xtool did not build: - an app supporting macOS below 13.0 was rejected as below the required minimum; - an x86_64-only app on Apple silicon failed the audit for lacking an arm64 slice, although Rosetta runs it; - an app without `LSMinimumSystemVersion` was audited at 15.0, the former floor. Add `ResolvedTarget.existing(triple:)`, which validates the triple's syntax without the build minimums, and `MacBundleAudit.runTarget`. It picks the main executable's slice for the host architecture, falling back to x86_64 on arm64. The minimum comes from `LSMinimumSystemVersion`, or else from the minimum recorded in that slice.

Contentslayout, picks device families and resource paths per platform, and stamps the SDK version into Mach-O headers. It shares 6 files with this branch:BuildSettings.swift,Planner.swift,Packer.swift,DevCommand.swift,PlannerTests.swiftandControl.md. Both PRs define how xtool represents a platform; one should be rebased onto the other's abstraction, or the abstraction should be agreed first.PackSchema,Planner,Packer,BuildSettingsandXcodePacker,--platformonxtool new/dev, and the BSP/LSP config. It shares 10 files with this branch.With #350, #362 and this PR, three platforms are in flight at once. The platform abstraction should be designed once.
Same code, different bug (expect rebase conflicts):

--tripleas every package's deployment target, so a dependency that declares a lower minimum compiles at the app's target and fails on APIs obsoleted there. The unversioned triple doesn't help: without a version, SwiftBuild builds Release universal, and on Linux it then has no way to build a single architecture. Native SwiftPM compiles each package at its own minimum and cross-compiles from Linux today.Bundle.moduleaccessor instead of replacing it. The native accessor looks next to the executable and then at an absolute build-machine path, so a signed.appwould only find its resources on the machine that built it. A-vfsoverlaysubstitutes an adapted copy that also searchesContents/Resources, as Xcode's accessor does. Package sources are not edited, and toolchain changes to the generated file are picked up or rejected rather than silently replaced. A plan-only run generates the accessors before the first compile, so builds cost the same asswift build(see the CodexBar numbers above).Open question for the maintainer
