Device Will not run error iOS 9 Xcode 7.0

Question

I recenlty upgraded my device to iOS 9.

The device will not work in Xcode 7.1, when tying to run get the error:

An error was encountered while enabling development on this device. Please try rebooting and reconnecting the device. (0xE8000076)

So I updated iTunes and dowloaded Xcode 7.0 as suggested here, cleaned and built. No luck.

Any input appreciated.

Answer 1

Well, it's worth trying to do as the error message proposes: reboot and reconnect the device.

UPDATE: it is possible, that two reboots are required. Take a look at comments to this answer.

UPDATE 2: If nothing else helps, try restoring the device.

Answer 2

Had the same problem now. I had Instruments open. When I closed it, Xcode would allow my iPhone. Might be worth a shot.

Answer 3

The explanation of issue and fix: - XCode 7 started to monitor connections from applications to the device - If XCode "does not like" the application or type activity between computer and iOS device - it displays such weird message

Fix - exit all applications that might communicate with iOS device: - AppCode - most probably it is causing issues - XCode instrumentation - usually not causing issues but sometimes might do - iTunes - never seen but it's also probable target

Just to have no side-effects it's better to have device rebooted (with cable detached) and make project Clean prior next attempt to run on a device.

Hope that will save you few minutes and some neurons in your brain
