Xcode10 random popup "The bundle identifier for XCode10Project.app couldn’t be read."

I've created a project in XCode10 Beta6. I closed the project and opened another project from XCode 9.2 At random points throughout working on another project, I get alert popup saying.

How do I resolve "The bundle identifier for XCode10Project.app couldn’t be read." issue with XCode10 Beta 6?

the popup appears every time after I test my xcode 9.2 project enter image description here

Solution

  • The solution is to delete derived data and clean project, as described here: How to Empty Caches and Clean All Targets Xcode 4 and later

    Deleting the offending project from disk will not fix it.
