Xcode 6 iPair Air unable to run App on Device (OS version)

Question

I have a valid Provisioning profile, added iPad Air ID to Developer Account, etc..

xCode cannot identify the OS version on a new iPad Air on a new Macbook pro, I have made all updated on Latest OS.

I get this error: Mike's iPad may be running a version of iOS that is not supported by this version of Xcode.

Answer 1

I was running Xcode 6, new iPad needed Xcode 6.1 but Apple Auto-update did not download the Update. You have to manually go to App Store and search for Xcode.

Answer 2

On iOS 8.1 you can only build (directly on the device, and not ad-hoc) starting from Xcode 6.1. I am not sure why apple did this, but this is the answer.
