Answer 1

If you have same issue in Xcode 10 (this worked for me using 10 beta 5 and iOS 12 beta 5) the steps are the same except it was necessary to restart the computer (restarting the iOS device, quitting and relaunching Xcode did not work).

1) Quit Xcode

2) Delete folder located at: ~/Library/Developer/Xcode/iOS DeviceSupport/ iOS version on target device

3) Restart Computer

You will need to either navigate to the user Library via Terminal or show hidden files in finder.

Toggle hidden files with: command + shift + .(dot)
