Solution of Application-identifier entitlement does not match problem

Here is a foreigner's answer:

This happened to me after installing a build from TestFlight and overwriting it with the debug build from Xcode.

Nothing helped, no clean build, no Derived Data voodoo ...

How I finally got it working was:

-Delete Debug build from Phone (and watch if it ' s still there).

-Download TestFlight build again.

-Install Test Flight Apple Watch app build from TestFlight app.

-Delete TestFlight Watch app build from Phone using the TestFlight app.

-Delete The TestFlight IOS app build from the phone

-now everything seems back to normal. I can run the debug build from Xcode.

But generally not so complicated. Just remove the Debug app from your device and you can. If it is deleted or not, then try it again in his own way.
