Xcode 12

Xcode will not let me run my apps externally on my phone. But the simulator works. I wonder if its because I have iOS 14 on my phone.I don't know if Xcode 12 works with iOS 14 I think somewhere it says it does but I think it might still be glitching. In the meantime I'll use the simulator. Anyone know any bypass yet or a fix I don't expect an answer this came out like 4 days ago lol.

Error:
Failed to prepare device for deployment.
If you are certain that Xcode supports development on this device, try disconnecting and reconnecting the device.

I have the same problem rebooting my iPhone and Mac Pro, runs fine in the simulator, when I launch the app on the phone, the screen just stays black, if I quick the run in Xcode the app will now launch on the phone. Any one else have this problem or a solution
