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

One possibility worth checking, if none of these other solutions work, is that there is no space left on the device. Xcode will not give you a helpful "device full" error to tell you that your device has no storage space left, but it will also not be able to deploy an app build to a device whose storage is full. The only solution in that situation is to delete media or other apps/data to free up enough space.
