Build failed with xcode 10 beta

Question

I created a new project on Xcode beta and built it, It gives me the below build error.

Encountered an error communication with IBAgent-iOS on launchscreen.storyboard.

The same storyboard error that I am getting when I try to build any sample projects built on Xcode 10 beta.

Has anyone come across the same issue with Xcode 10 beta IDE?

Answer 1

I face the same issue with Xcode 10.1... issue resolved by just clean the build folder using Command+Shift+K

I hope this will work for you.

Answer 2

I'm on Xcode 13 and still get the issue sometimes. No help with cleaning the build folder or removing DerivedData.

However, this usually saves my life ^^
