Xamarin.iOS app launch crash, no crash logs and no failure message in console

I am trying to run my application in the latest version of Xamarin studio 5.10.2 with iOS 9.2 simulator and device, but each and every time when I try to run my app my app will just display splash screen and immediately it crashes. No crash logs is getting generated nor a failure message in console.

I tried clean build, cleaning Xamarin studio cache data, resetting simulator, cloned a fresh copy of my project but unfortunately none of these things are helping me out :(.

P.S: The same app and the same git branch is working like a charm for my team members inn their machines, I just wonder with this strange behaviour of Xamarin studio! ; Other projects are running successfully in my machine except one of the main project.

Any help in resolving this issue is much appreciated in advance.

Try to catch any unhandled exceptions by adding this to the Application static void Main 

AppDomain.CurrentDomain.UnhandledException += (o, e) => 
{ 
    #if DEBUG
        Debugger.Break ();
    #endif
};

TaskScheduler.UnobservedTaskException += (o, e) => 
{
    #if DEBUG
        Debugger.Break();
    #endif
};

EDIT Also a good suggestion would be to install a crash analytics tool (like Hockeyapp) to catch any other crashes.

I once faced same problems as yours. I would like to share. What I do is:

  1. Search and delete the unused NuGet Packages, components and references in my coding.
  2. Clean up solution, quit Xamarin Studio.
  3. Delete folders /bin and /obj in Project folder in both Android and iOS project.
  4. Open up the project, Rebuild All.

Then, the app works well.
