What is a thread when it comes to the app delegate portion of Xcode?

42,016 PointsFrom apple's Threaded Programming Guide:
Threads are a relatively lightweight way to implement multiple paths of execution inside of an application. At the system level, programs run side by side, with the system doling out execution time to each program based on its needs and the needs of other programs. Inside each program, however, exists one or more threads of execution, which can be used to perform different tasks simultaneously or in a nearly simultaneous manner. The system itself actually manages these threads of execution, scheduling them to run on the available cores and preemptively interrupting them as needed to allow other threads to run.
Did your app crash and throw an exception or something? if so can you post whats logged in the console?

13,225 PointsThank you for your help. I was doing the crystal ball app and when i go to animate the app, there are no errors shown but when it compiles it states at the bottom of the screen: terminating with uncaught exception of type NSException. Then it takes me to the app delegate page and highlights this in green: return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class])); and it says thread 1: signal SIGABRT. Im not sure what this all means or what i did wrong. Thank you again for your help!
