Xcode crashes on every launch attempt with identical CoreSimDeviceIO framework failures. This started after an automatic Xcode update and affects multiple Xcode versions. Versions tested (all crash identically): Xcode 16.0 (26.0/24228) Xcode 16.4 (23792) *Unable to download Xcode 15.4 due to my ios
Crash signature: Exception Type: EXC_BAD_ACCESS (SIGKILL Code Signature Invalid) Crashed Thread: 0 (main thread) Crashing Framework: CoreSimDeviceIO.framework Termination Reason: CODESIGNING, Code 2 Invalid Page
Troubleshooting completed: Multiple fresh Xcode downloads from Apple Developer portal Security database rebuild and SystemPolicy reset Complete macOS clean reinstall Developer tools reset (xcode-select) NVRAM reset Hardware diagnostics (passed)
Additional problem: macOS compatibility enforcement prevents installing Xcode 15.x as a workaround, showing "update to latest version" errors even for properly downloaded older versions. Current status: Unable to perform iOS development. Bug report submitted to Apple (FB# FB20308027).
Has anyone with similar MacBook Pro hardware (mid-2019) encountered this? Any successful workarounds for the CoreSimDeviceIO crash or compatibility enforcement blocks? Is there something that I am missing?
