There is this black magic, that if you are seeing something is wrong / not working with Xcode, you may just need to restart it
For example, today I encountered into this issue:
Build failed:
No matching provisioning profile found: Your build settings specify a provisioning profile with the UUID “......”, however, no such provisioning profile was found.The first thing came into my mind is to restart the Xcode. And you know what? It works!!
