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

I run into this problem quite often (at least like 5 times a week). Almost every time this happens, a Xcode restart fixes it. But this time nothing seemed to work including:

• Restarting Xcode;
• Unplugging and re-plugging the iPhone;
• Cleaning the project (cmd+shift+k);
• Cleaning derived data (cmd+option+shift+k)

Done dozens of times in all sorts of different orders.

What fixed the issue for me this time was simply:

✅ Rebooting the Mac.
