I am using Xcode 11.0 beta and since two days I am stuck on this error. half of the project is built on SwiftUI.. I wonder if this is the reason that the error is coming...
I have tried restarting my Mac, deleting derived data, building and cleaning the project, updating the pods
I think think this problem is caused by SwiftUI
It usually tells you the reason when you click on it you can read about your problem , maybe a file is deleted or missing . or if no logical reason was found , clean build your project it'll be ok . don't worry .
