Anyone got any ideas how to resolve? I've tried restarting my mac and iPhone multiple times, it makes no difference.

  • You state that you're using the latest version of Xcode -- there are multiple ways to interpret that, including "latest released Xcode" (Xcode 12.5), or "latest beta of Xcode" (Xcode 13.0 beta 1). You need Xcode 13 -- please confirm that is the version you're using, and not Xcode 12.5.

Try restarting your iPhone.

I know this sounds silly, but it works for me most of the time.

I have solved this problem by removing my iPhone from the Devices List in Apple Developer Account.
