iOS simulator crashes at startup (intermittently), no crashes on device

My app crashes on the iPhone 6.1 Simulator. It crashes on startup, but not every time. In fact, I can't get it to crash two times in a row. Sometimes it's every other time I hit run, sometimes it's every three times I hit run. The crash is a SIGABRT and produces no error messages. I set a breakpoint on all exceptions, but it always breaks at UIApplicationMain(...) in main.m

The backtrace produces:

* thread #1: tid = 0x1c03, 0x91398a6a libsystem_kernel.dylib`__pthread_kill + 10, stop reason = signal SIGABRT
frame #0: 0x91398a6a libsystem_kernel.dylib`__pthread_kill + 10
frame #1: 0x95c31b2f libsystem_c.dylib`pthread_kill + 101
frame #2: 0x023e857b libsystem_sim_c.dylib`abort + 140
frame #3: 0x02d92b4e GraphicsServices`GSRegisterPurpleNamedPort + 348
frame #4: 0x02d9269f GraphicsServices`_GSEventInitialize + 123
frame #5: 0x02d92c1f GraphicsServices`GSEventInitialize + 36
frame #6: 0x00ee0d99 UIKit`UIApplicationMain + 600
frame #7: 0x0000277d MyApp`main(argc=1, argv=0xbffff388) + 141 at main.m:16

The app doesn't seem to crash on the device, but this is very annoying and just started recently. I've tried resetting content, restarting Xcode, restarting my computer -- no luck. Any ideas how I could debug this?

Had a very similar problem and found changing the Deployment Target from 6.0 to 5.0 fixed it for me. Obviously only if your App will work on 5.0 will this work.

Yep, this happened to me with the beta 10.8.4 as well. Only solution is to stop the app, wait a couple seconds, then rebuild on the simulator. Just pressing build/run once a build is currently running is what causes this.

* Update * As of Xcode Version 4.6.3 this issue has been addressed. If anyone is still having issues please post it here.

Try editing the scheme and switching the debugger from LLDB to GDB (or vice versa) and see if it helps.
