Xcode 27 removed Contents/Developer/Applications/Simulator.app in favor of Contents/Applications/DeviceHub.app, so `open -a Simulator.app` fails with "Unable to find application named 'Simulator.app'". Resolve the app from `xcode-select --print-path`, preferring DeviceHub.app, then Simulator.app, then falling back to opening Simulator.app by name. This matches flutter_tools (flutter/flutter#187910).

## Description Xcode 27 no longer ships `Contents/Developer/Applications/Simulator.app`; the simulator UI is now `Contents/Applications/DeviceHub.app`. `XcodeUtils.openSimulator` hardcodes `open -a Simulator.app`, so on macOS 27 / Xcode 27 the "Open iOS Simulator" action (and bringing an iOS simulator to the front when running) fails with: ``` Error Opening Simulator Unable to find application named 'Simulator.app' ``` This change resolves the app from the selected Xcode (`xcode-select --print-path`), matching what `flutter_tools` already does after flutter/flutter#187910: 1. `<Xcode>/Contents/Applications/DeviceHub.app` (Xcode 27+) 2. `<Xcode>/Contents/Developer/Applications/Simulator.app` (older Xcode) 3. `Simulator.app` by name (previous behavior) `xcode-select` runs on the app executor rather than the EDT, and is bounded by a 5s timeout. `isSimulatorRunning` also recognizes the `DeviceHub` process, which is what gates whether "Open iOS Simulator" is enabled in the device drop-down. ## Manual test steps 1. Quit the simulator UI and shut down simulators: `killall DeviceHub Simulator; xcrun simctl shutdown all`. 2. `./gradlew runIde`, then open a Flutter project in the runtime workbench. 3. Toolbar device drop-down → **Open iOS Simulator**. - Expected: the simulator UI opens (DeviceHub.app on Xcode 27+, Simulator.app on older Xcode), no "Error Opening Simulator" balloon. - Before this change on Xcode 27: `Unable to find application named 'Simulator.app'`. 4. Re-open the drop-down: the booted simulator is listed as a device and **Open iOS Simulator** is disabled (exercises the `DeviceHub` process check). ## Verification performed On macOS 27.0 (26A428), Xcode 27.0 (27A266a), Android Studio 2026.1.2.8: - 4 new `XcodeUtilsTest` unit tests pass (DeviceHub, DeviceHub preferred over Simulator, Simulator fallback, name fallback). - The runtime workbench was launched with the patched plugin and a Flutter project opened in it. The toolbar click could not be automated on this machine, so the action's code path was exercised directly from a platform test calling `XcodeUtils.openSimulator(null)` — the same call `OpenSimulatorAction` and `FlutterDevice.bringToFront` make — with no simulator running: ``` [manual] simulator UI running before: false [manual] simulator UI running after: true ``` DeviceHub.app launched and `isSimulatorRunning()` detected it. (Scratch test, not included in this PR.) - Shell baseline on the same machine: `open -a Simulator.app` → `Unable to find application named 'Simulator.app'`; `open -a /Applications/Xcode.app/Contents/Applications/DeviceHub.app` → opens the simulator. - Not verified on hardware: the older-Xcode `Simulator.app` branch — only Xcode 27 is installed here, so that path is covered by unit tests only. --- - [x] I’ve reviewed the contributor guide and applied the relevant portions to this PR. - [x] I've included the required information in the description above. - [x] My up-to-date information is in the `AUTHORS` file. - [x] I've updated `CHANGELOG.md` if appropriate.
