[Solved] Xcode iPhone app runs and crashes immediately

by


Your project is too small to even try all debugging tools in the armor. If I were you I would start with these following steps to eliminate the root cause and investigate into the issue.

a) Try creating a new sample project with same steps that you did in current project and try running it. If all goes well, it might be some glitch with some plugins in XCode,which might have resulted in corrupt files.
b) If the issue persist, try using break point on various methods viz

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
- (void)viewDidLoad
- (void)viewWillAppear:(BOOL)animated
- (void)viewDidAppear:(BOOL)animated

Most probably these steps should reveal as to what stage do you reach before you reach the stalling screen.
