The process exited abnormally. The most common cause of crashes with this exception type are uncaught Objective-C/C++ exceptions.
App Extensions will be terminated with this exception type if they take too much time to initialize (a watchdog termination). If an extension is killed due to a hang at launch, the Exception Subtype of the generated crash report will be LAUNCH_HANG. Because extensions do not have a main function, any time spent initializing occurs within static constructors and +load methods present in your extension and dependent libraries. You should defer as much of this work as possible.
