I recently saw a similar issue, and my workaround was to delete the LaunchScreen.storyboard but not commit the change. You might want to make sure you're using the latest Xamarin packages on your Mac. Also, restarting Mac and/or VS usually fixes small issues.

[uzairali001]

What do you mean by

delete the LaunchScreen.storyboard but not commit the change.

I'm indeed using latest mac os, itunes, xcode, xamarin packages, visual studio etc and also did restart mac, visual studio, windows multiple times, clean project, delete bin and obj folder, delete mtbs folder on mac but still issue persist.

later I resolved this issue by changing build action from InterfaceDefinition to None then I got different error something about assets, to resolved that I also delete XSAppIconAssets and XSLaunchImageAssets key from info.plist now everything seems to be working perfectly fine.

I don't know how icon is still showing up even though XSAppIconAssets and XSLaunchImageAssets not exist anymore in info.plist .

Hi @uzairali001, thanks for reporting!

I've tried to reproduce it but unfortunately am not able to. Although I know you say to just go through steps 1 and 2, this behavior is not visible to me. Would you maybe able to add a repro project to issue that does show this issue? That way we might be able to figure out what is going wrong for you.

Would you maybe also be able to add your full Visual Studio info by going to Help > About... and click the Copy Info button?

[davidvasquezr]

I had the same error. I updated macOS
Catalina and Xcode 11 and the error was resolved.

[jfversluis]

@uzairali001 is that something that you are able to confirm?

[uzairali001]

Indeed the problem is resolved by updating macOS to Catalina.

[eliotg]

in case this helps someone who, like me comes across this bug because they encountered the titular error... in my case, it was because, in my interface.storyboard, the destination IDs of the button connection actions were other than the ID of the overall controller. Once those connection actions were pointing back to their parent, everything compiled just fine.

Anyone else runs into this after an OS upgrade or Xcode upgrade, please try
delete files here ~/Library/Developer/Xcode/DerivedData
Then restart xcode. Visual Studio should build and run you code again.
