Ineligible Devices section appeared in Xcode 6.x.x

Question

After installing Xcode 6 my devices moved to greyed-out section Ineligible Devices and I can't select them as deploy target:

Update:

This error occurs in all versions of Xcode 6.x.x. There are so many different reasons causing this problem

Answer 1

With the release of Xcode 6.3.1, check first the Update 5

1. Verify that "iOS Deployment Target" is <= the version of your iDevice.

You find this option in "Build Settings" tab when you click on a target of your project in Xcode.

2. Then if does not work, try to restart Xcode. Sometimes we have to restart the Mac and iPhone/iPad. Take a look at the Updates below before restarting Xcode

3. Update: in Yosemite, Xcode 6.0.1 does not support iOS 8.1, you have to update to Xcode 6.1 if you want to debug on iOS 8.1 device, or you will probably have the same problem as described in the topic

4. Update 2: Xcode Beta 6.3 does not support iOS 8.2 (and also 8.1 - thanks @steveb). You won't see your device in deploy target list. I don't know if other versions are supported.

5. Update 3. Use Xcode 6.2 instead of Xcode 6.3 beta in order to debug with a device running iOS 8.2

6. Updated 4 : for Xcode 6.3 (and eventually 6.3 beta if someone use it :) ), if you have this problem, just go to Product > Destination to select your device. Even though it says your device is ineligible, it will still allow you to select it. If your device version is >= target version, the build should work. It must be a bug for Xcode 6.3 in debug with iOS 8.3 (or maybe other iOS version) (thanks @einfach).

7. Update 5: Apple released Xcode 6.3.1 that fix the issue of ineligible device. If you have this problem with Xcode 6.3, upgrade to XCode 6.3.1

From Release Notes (Xcode 6.3.1):

Fixed: Devices previously listed as "ineligible for running” erroneously are listed correctly. (20121178)
