I ran into this problem recently, most likely it can be caused due to the reason, that your iOS Device is running a higher version than you xcode can support.

Example:

Apple release new iOS for iPhone i.e. 14.2 and you upgrade your device right away, than you ran into this issue, because the xcode may not have the latest version of your device support files, meaning xcode can only suuport iOS 14.1 or lower. Apple sometimes release newer iOS without providing update of xcode device support files.

There is 4 solutions for this:

1. Keep your iOS Device on the current stable version of xcode
2. Downgrade your current iOS device
3. Install device support files manually
4. Install xcode beta from Apple Developer https://developer.apple.com/download/

It is an annoying issue, Apple should not release any iOS without having the supporting tools released at the same time, or they should run a warning.
