Notes:

  • Doesn’t reproduce if running without Xcode debugger
  • Only reproduces on first run from Xcode
  1. Resolution Note:

    The keyboard input hang occurs only when the app is launched from Xcode in debug mode, and only during the initial launch. This issue does not arise in any other scenario. When the hang occurs, Xcode’s console displays messages such as “Hang detected: 1.64s (debugger attached, not reporting)”, “<0x105a2a080> Gesture: System gesture gate timed out”, and “App is being debugged, do not track this hang”. These messages indicate that the hang is expected behavior when running in debug mode with the debugger attached. When the app is run without the debugger, the hang does not occur.
