Xcode 6 error: “Embedded binary's bundle identifier is not prefixed with the parent app's bundle identifier.”

Question

I\'m trying to build an extension project and Xcode keeps throwing the error in subject.

Answer 1

The problem is likely that you added a folder using "Create folder references" when adding it to your project (like I did). @Jacob's fix didn't work for me :(

I had to delete the folder reference I added to my project, then clean and build, and that fixed it for me.
