My problem was building the application with a production provisioning profile. in my case, the solution was to switch to the development provisioning profile. Then it worked :)
I rebooted my iPad, and it eventually worked...
So this started for me after I updated Xcode to version 12, and my iPhone to iOS 14. The fix was as listed above (multiple times) to unpair, reconnect, and trust the computer, BUT only after changing the target to iOS 13 in Xcode did those steps actually work. Once it was reconnected I was able to switch the target back to iOS 14 inside Xcode. This one was frustrating.
I had issues with Xcode 11.5 and iOS 13.5.1
Sucessful:
Not successful:
For me it was the exaxt opposite of the message. Xcode was up to date, but the iphone I was trying to run on was not updated to the latest version of iOS. 13.7
was the version at this time.
After updating to 13.7
the iPhone, everything went back to normal.
Or Xcode is just not smart enough to know that your iPhone iOS version is newer than the one supported by Xcode! I had this issue, been trying all solutions until I updated my Xcode from 11.4 to 11.5
