I'm not able to test this on macOS 26, but all tests and usage pass on 27. The fix should be applicable to both versions, but it only surfaced as an issue now due to the synchronous stalling change. |

Issue:
AppState.initloads cached available Xcodes, which assignsavailableXcodes. That observer was doing installed-Xcode discovery synchronously on the main thread. On macOS 27 beta, that blocks insidewaitUntilExit()while SwiftUI/AttributeGraph is creating@StateObject AppState, causing the launch crash.#815
Fix: remove installed-Xcode discovery from the
availableXcodes/selectedXcodePathobservers. They now use cached installed-Xcode state only. Installed Xcodes are refreshed asynchronously after launch and before update/install resolution; install resolution refreshes without recomposingallXcodesso progress state is preserved.
