[ios] Ineligible Devices section appeared in Xcode 6.x.x

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

Check this solution list for more details.

Simply deploying to another device and then switching back to the former 'ineligible' device worked here. (saved the hassle of restarting anything)

My iPad was 8.0, but i had deployment target set to 8.1. I changed the deployment target in build settings, and immediately, the ipad moved out of the "ineligible" category. (I am on Yosemite and XCode 6.1)

I simply restarted my Mac and my iPhone 6 and the problem was solved. I never had to change my deployment target.

If you have a chance to run any project on the 'ineligible' device from other Mac with Xcode, try it and then reconnect the device to your Mac (without restarting Xcode/Mac).
For me, after doing that, the 'ineligible device' section disappears and my device returns to the normal status.
Hope it helps for someone.

Besides setting iOS Deployment Target to iOS 8.0, also restart your iOS8 iPhone/iPad. This did the trick for me.

Changing your deployment target is not a good idea to solve this problem (it will change which iOS versions you support on the app store).

What I did is restart just Xcode and it was fixed.

Fixed in Xcode version 6.3.1 (6D1002) published April 21, 2015.

At least the problem magically went away for me after installing this Xcode version.

What worked for me is to install XCode 6.1 (compatible with iOS 8.1)

Please check you device iOS version and your Xcode application build target version. This might be causing the issue.

I'm using the 6.3 Xcode Beta. I had the same issue as above. I restarted my computer and phone but did not work. Simply went to the build target under build settings and changed build target to 8.1. I hope this is fixed in the next released. Make sure that after you change your build setting - you need to restart your device and Xcode!

I can confirm that the answer it to upgrade Xcode to 6.1. If you are using Xcode 6.0.x you will not be able to select a device running 8.1. Your deployment targets and OS version should have nothing to do with this.

If your OS version is greater than 10.9.4 I would recommend this. First, un-attaching all devices. Download Xcode 6.1. After opening the new version of Xcode attach your device. You should be good to go.

Another good thing would be to look at the release notes. It's and easy read and gives you a general idea of what still needs to be fixed.

Upgrade XCode to ensure that it supports your current iOS version on device.

(In my case, my phone was on iOS 9.1.x) `but XCode version was 7, which supported iOS 9.0 devices)

I set my "iOS Deployment Target" in "Project" and "Targets" from 7.1 to 8.0 and restarted Xcode (with "Quit") and it worked.

My solution was that I had recently upgraded my iOS device to 8.3 and Xcode still didn't recognize it. The fix was to simply upgrade Xcode to 6.3 :)

You can try below solutions to run build in your device.

1. Restart your iOS device (If device is recently updated) and your Xcode.

2. Make Sure that in build settings "iOS Deployment Target" is <= the version of your iDevice.

Otherwise you can goto - Product > Destination, select your device which would be showing as ineligible device.You will be able to select your device and run your build.

I also came across that if you have the iOS 8.4 then your Xcode doesn't have the SDK for iOS 8.4 due to which devices show as ineligible. To solve this issue

Download Xcode 6.4

Everyone should note that there seems to be a bug in XCode 6.3 (Beta and GM) that is aggravating this problem.

I have iOS 8.3 installed on my device. Setting the build target to iOS <= 8.3 did not help. Nor did any of the other solutions posted.

What worked for me:

Go to the Product Menu > Destination and select your device. It will be listed under "Ineligible", but you will still be able to select it. After doing this, I was able to build and deploy to my device.

I found the following useful:

1. Connect to the new device, go to itunes, make sure you sync the device (you might have a certificate issue)
2. Follow NateJC's advice (i.e. switch devices and switch back again)

Tried all possible Updates, with Xcode 6.3, iOS 8.3 and OSX 10.10.3, but didn't got a permanent solution.

Kudos to skywinder,the first option worked!

My iPhone has updated to iOS8.1. My Xcode version is 6.0.1, and my mac os version is 10.10. When I want to run app in my iPhone, there is a section named Ineligible Devices(OS Version). Then I update Xcode to 6.1 version, solved problem.

Part of Xcode 6.1 release note: Includes SDKS for OS X 10.10 Yosemite, OS X 10.9 Mavericks, and iOS 8.1.

That is, Xcode 6.0.x don't support iOS 8.1.

I agree with txulu, changing the deployment target is a ridiculous idea. I need to support devices back at least one version, that is non-negotiable to me.

Restarting my iPhone 5 after updating to iOS 8.1 and Xcode to 6.1 worked for me.

I had a similar issue and for me I had upgraded to iOS8 and also changed the name of my Xcode project. The fix for me was to create a new scheme by selecting Manage Schemes > (+) button.

After doing this, my list of devices returned.

For iOS 9.1+ devices, the Xcode version should be upgraded to 7.1 (even 7.0x will not work)

My answer, perhaps listed already but i did not notice, was simple: I deleted the app in question from the target itself, then fired up Xcode and the target was then available. And yes, i tried most of the other suggestions, and was resorting to activating the target from the Product menu, but that was getting tedious.

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)

Ran into the same issue, using Unity3D

=> Xcode 6.3 requires Unity 4.6.4

If you're using an older Unity version (e.g. 4.6.3) you'll always get your devices in the Ineligible Devices section

The most common cause for this issue is Xcode 6.3 and running iOS 8.2 on your device. Xcode 6.3 doesn't install the 8.2 simulator by default. It has the 8.3 simulator installed.

The solution by @joshstaiger works, but it is not a permanent fix. You have to do this each time you want to run the app on your device

The permanent fix is to simply install the 8.2 simulator in Xcode 6.3. Go the Xcode -> Preferences -> Downloads. Install the 8.2 simulator under Components.

Now you will no longer see your device listed under ineligible devices.

make sure the deployment target version in setting is lower or equal than the iphone version

if the deployment target is 7.1 but the iphone is 7.0.3

you will see that error message

I changed my deployment target to 7.1 the same as my iphone, and now I can run swift programs on it. It was on 8.0 and showed up as ineligible.

For most people the cause of the problem is probably mismatch between Xcode, device version and app target version.
If versions are not a problem for you, most likely is that the device (iPhone/iPad) has been used with another Mac to copy apps to. This happens particularly more with a team environment where an iDevice can be used between team members. Xcode knows some other developer's Mac has connected to this device, it will show up as "Ineligible". But the previous Mac that connected to it, it will show up as normal.
The quickest work around is as shown by joshstaiger among others:
Go to Xcode ->Product->Destination
Select the ineligible device as target. It should work.

In my case I had to reattach device and when it asks press "Trust this computer", then my device appears available again in xCode

After trying the 2 answers above (changing deployment target and restarting my iOS device), what finally fixed it for me was restarting my Mac.
