Objective_C Exception Thrown when debugging Xamarin C# iOS App

When I go to build and debug my iOS app, the simulator runs but I get an exception thrown and the simulator doesn't open. I'm using Visual Studio for Mac.

The error is:

Objective-C exception thrown.Name: NSInvalidArgumentException Reason:  
Could not find a storyboard named 'Main' in bundle NSBundle

Okay, the weirdest thing fixed it. I installed an older version of Xarmarin iOS that I got from this page: https://bugzilla.xamarin.com/show_bug.cgi?id=38206

Then when I opened Visual Studio it didn't detect it and had me update it. After updating it, my app was able to debug and the simulator worked fine! Very, very weird!

It seems like no main.storyboard can be found in your project. Check this pic

if the Main Interface is Main , check if main.storyboard exsits in your project. Or you can change it to other viewController.
