iPhone won't connect in Xcode 6 beta

Question

I updated both iOS 8 and Xcode 6 beta. When I connect my phone, it shows up as \"ineligible device\" where you select which platform you want to run on.

Answer 1

After installing new version Xcode, propose install additional components for debugging. If these components not installed, propose Xcode again for installation. Simplest way to check for existence of required components:

1. Relaunch Xcode
2. Install required components

This is worked for me!
