feat: Add tvOS simulator support - #292
Conversation
mobilecli can now list and drive tvOS simulators, not just iOS ones. - Recognise tvOS runtimes when parsing the simulator runtime string and report the `tvos` platform. Version parsing now also handles tvOS, watchOS, and xrOS. - Pick the DeviceKit runner bundle id and process name based on the platform, so the `devicekit-tvosUITests` runner is found on tvOS. - Install the arm64 tvOS runner artifact during agent install, with its own version and checksum entries. - Map the tvOS Siri Remote buttons (UP, DOWN, LEFT, RIGHT, SELECT, MENU, PLAY_PAUSE) in the WDA press-button client. - Include tvOS devices when resolving device model metadata.

📝 WalkthroughWalkthroughThe change adds tvOS simulator support, including runtime detection, platform-specific agent installation and discovery, arm64 artifact selection, Siri Remote button mappings, and updated device abstractions. ChangestvOS simulator support
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The PR adds tvOS discovery, control, and runner installation, but the current implementation can select the wrong runner for unsupported runtimes, lose cleanup of a newer runner, fail agent installation because of the unpublished checksum, and leave related integration behavior inconsistent. The PR is not merge-ready without fixes or explicit owner acceptance. Sequence Diagram(s)sequenceDiagram

- Around line 31-33: The pinned tvOS archive checksum in the install mapping is
still tied to a locally built artifact, so the new tvOS path in
downloadAndInstallAgent() cannot verify the GitHub release successfully. Update
the checksum/version entry used for the devicekit-tvos-Sim-arm64.zip artifact to
match the published release before shipping, or add an explicit early error in
downloadAndInstallAgent() / the tvOS install path that reports the runner is not
published yet instead of attempting the install.

@setoelkahfi thank you so much for this PR. I'll take a look. I see you also updated mobile-mcp, thank you so much for this! This also means mobilewright may inherit this automatically :). I'll review. |

hey @gmegidish , friendly bump, could we get this in? it'd be really helpful so I can iterate on adding support for the real tvOS device happy to address any feedback |
|
@setoelkahfi thank you for this. I need time to actually test it on a simulator, to make sure it all works. and it also depends on a change in devicekit-ios. I'll get to that soon. sorry it's taking me so long :( |

What
mobilecli can now list and drive tvOS simulators, not just iOS ones.
Changes
tvosplatform. Version parsing also handles tvOS, watchOS, and xrOS.devicekit-tvosUITestsrunner is found on tvOS.agent install, with its own version and checksum entries. The tvOS runner is arm64-only for now.Notes
The tvOS runner checksum currently points at a locally built artifact. Update it once the runner is published from a devicekit-ios release.
Testing
mobilecli deviceslists a booted tvOS simulator withplatform: tvos, andio buttonpresses move its focus as expected.Related
