I have this error with xcode 8 GM:
MyApp has conflicting provisioning settings. MyApp is automatically signed, but code signing identity iPhone Distribution: Francesco Scala (2************O) has been manually specified. Set the code signing identity value to "iPhone Developer" in the build settings editor, or switch to manual signing in the project editor.
I have to publish the app to the store but doesn't work!!!! Help I'm hating Apple now, sierra and Xcode together are very bugged!
