It says **failed to launch in time**, so this may help: [Application Failed to Launch in Time](http://stackoverflow.com/q/3908882/1402846). — Pang, Jan 23 '13 at 11:14

The best applications launch quickly, allowing the user to interact with the application as soon as possible. To provide a quality user experience, you should routinely evaluate and work to improve the launch time of your application. If considerable work must be done at launch, consider performing that work on a secondary thread and visually indicating the activity. http://developer.apple.com/library/ios/#qa/qa1592/_index.html

Application launch time have some restriction by time. You must look at AppDelegate.m Most likely, in - (void)applicationDidFinishLaunching:(UIApplication *)application method you start some very long operation. For example:

AppDelegate.m

- (void)applicationDidFinishLaunching:(UIApplication *)application
{
  ...
  [[SomeProvider sharedOnlineDataProvider] initializeEngine]; // << this may be very long
  ...
}

So, you can try to use

[[SomeProvider sharedOnlineDataProvider] performSelectorInBackground:@selector(initializeEngine) withObject:nil];

Obviously, initializeEngine must be thread safe

It looks like your app is taking to long. When you search for the exception type, you will find: http://developer.apple.com/library/ios/#qa/qa1693/_index.html

Are you doing a lot in the AppDelegate didFinishLaunchingWithOptions? If so, then do that in a background thread.

I think you need to link your dSYM file to the crash log and find what leads this crash. You can refer to this article to learn how to use symbolicatecrash to change the crash log back to method call stack.
