To create build always need to quit the xcode or clean the project for many times. Looking for a permanent solution.

Answer 1

You can try it by deleting derived data from Xcode -> Preferences -> Locations -> Derived data

Then clean the project and run.

Answer 2

I just had this issue and its due to path references. You cannot move folders or files in or out of the Xcode project once it's built. . xcodeproj file should stay outside of the project folder. If you're moving files around or copying folders, check .xcodeproj outside of the main project folder and verify that the folder and file structure is still intact.
