Answer 1

If you are using the Xcode 7 GM build version 7A218, the chances are that you accidentally downloaded iOS 9.1 (13B5110e) as opposed to the iOS 9 GM build (13A340). I did the same thing don't worry. They are too close to each other on the downloads page :0

You can check which version you have on your device by simply going to your device Settings > General > About > Version

All you have to do is download the correct iOS 9 GM build and go to iTunes. Click on your device. In the summary tab, OPTION + Right Click "Check for Update" and restore your device by navigating to the iOS 9 GM build finder location. Note by selecting "Check for Update" you will not lose any settings or data on your device. In other words, it is not a restore

However, if you are using Xcode 7.1 build version (7B60) iOS 9.1 is supported

Answer 2

I had the same problem and all I had to do was to update my XCode to 7.1. After that it worked. Your Xcode has to be updated to the latest version.

This is also encountered when trying to use Xcode 6.4 against an iOS 9.0.x device. Here's how you can workaround it and get Xcode 6.4 to recognize your iOS 9.0.x devices:

1. Download Xcode 7.0.1:

http://developer.apple.com/devcenter/download.action?path=/Developer_Tools/Xcode_7.0.1/Xcode_7.0.1.dmg

2. Open Xcode_7.0.1.dmg and drag the Xcode.app to your desktop

3. Right-click, Show package contents, navigate into /Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

4. Copy the "9.0 (13A340)" directory to the existing DeviceSupport directory for your Xcode 6.4 install. For example: ~/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

5. Restart Xcode 6.4 (if it was running), and your device running iOS 9.0.x should now show as a recognized device.

Answer 4

I solve this problem by just simple xcode restart.

Answer 5

Update Xcode. If it not help: go to

/Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

If you don't find there your device iOS version, you could try to copy last one and rename it to which one do you need, restart XCode and try to compile, it works for me.

Answer 6

Apple just released the new Xcode 7.1 which support iOS 9.1. Update Your Xcode and everything will be fine.

Answer 7

I have experienced same issue

Could not find Developer Disk Image

1) My Xcode version was 7.0.1 and i updated my iPhone to version 9.2, then upon using Xcode my iPhone was shown in section of unavailable device. Just like in image below:

2) But then i somehow managed to select my iPhone by clicking at
Product -> Destination -> Unavailable Device

3) But that doesn't solved my problem and started showing

Could not find Developer Disk Image

Solution) Then finally i downloaded latest version of Xcode version 9.2 from https://developer.apple.com/downloads/ and everything worked fine for me.

Answer 8

For me the problem was that I just needed to open my phone and click "Trust Computer"

Answer 9

I had XCode 7.0.1 installed + iOS 9.1 (13B143).

XCode had shown me "unsupported device" / "could not find developer disk image" in Devices windows until i updated my XCode to version 7.1. Everything works well now.

Answer 10

I had already update to newest version Xcode (7.0.1) but still can't build on iPod touch 5 in iOS 9.1(13B143).After copy 9.1 (13B137) folder from my colleague to DeviceSupport folder in Xcode, it works! Not sure it would create some side effects.
