XCode crash every second time.

I have XCode 4.6.2 (4H1003) and MBP retina.

When I run my project in simulator, it crashes every second running without any error message in debug console.

return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));

The error is “Thread 1: signal SIGABRT“. Annoyingly, XCode does not give any error.

According to the this guy, it is because of debugger and something with latest iTunes. And he found the solution.

1. Go to “Product” -> “Scheme” -> “Edit Scheme”

2. Change debugger to “GDB” instead of “LLDB”
