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

Recently I have met the Xcode shows "development cannot be enabled while your device is locked, Please unlock your device and reattach. (0xE80000E2).

If your iOS device is already unlocked and connected to mac and still get the error from Xcode 8.1 after upgrading to iOS 10.1.1, then the mac is not trusted by the device.

To fix it, first disconnect device to mac and then go to iOS settings app, and open general->reset->Reset Location & Privacy.

Then connect device to mac and when prompted, set select trust the mac.

Then wait the processing symbol files within your device and mac. After it finished, you can run the project to your device. It will be working.
