I have a free developer account and had been able to test on my personal iPhone until Xcode 13.
Now the iPhone displays the untrusted developer error when I try to run my app on it using Xcode 13.
My iPhone is at: 15.0.2, Mac is at 11.6
I don’t have a spare phone to set up a new Apple ID as some have suggested as a work around.
Thanks in advance!
I think there is a time limit on how long one can actually run the app on a physical device with a free account, I used to have a free account and after some time the app will just stop running. I believe your only option now is to run it on a simulator or buy the Developer subscription...or if you find someway to delete the current certificate and reinstall a new one...
