Xcode “Device Locked” When iPhone is unlocked

Question

When I tried to build and run, Xcode said my device was locked. I looked at my iPhone, and it\'s not locked at all. How do I fix this?

Answer 1

From the Window Menu in top bar of Xcode, select Devices and Simulators.

(or Press SHIFT + COMMAND + 2)

Then select your device, right click and select Unpair.
Once you do this Trust or Don't trust will appear on your device.
Trust the device again and it will begin preparing it for Development.
Wait for Xcode to pair device for development and then you are good to go!
