Answer 1

I started getting the OP's error after updating my iPhone to iOS 13.5.1. Here is what worked for me to resolve the issue:

1. Unpair the iPhone (as per answer from @Jeff above).
2. Upgrade Xcode to latest, in my case 11.5 (which I believe is the first version of Xcode to support building to iOS 13.5.
3. NEW: I launched Xcode after updating to 13.5 which prompted me to "Install additional required components" which I did. Xcode extra step after updating
4. Reconnect/pair iPhone in Xcode's Devices window and Trust the computer.
5. NEW: After pairing the iPhone make sure you check the "Connect via Network" checkbox for the newly paired iPhone. By default Connect via Network is unchecked. Important step after re-pairing device

The "NEW" steps are not steps I've seen in previous answers, so I posted this answer.
