Xcode error "Could not find Developer Disk Image"

For people who would have similar problems in the future, beware that this problem is fundamentally rooted in the mismatch of your iOS version and Xcode version.

Check the compatibility of iOS and Xcode.

I personally downloaded Xcode 6.4 beta and 7.0 beta and I was very happy to find the solution by searching "8.4" inside the application folder of the 6.4 beta. By doing this, I found the folder 8.4 (12H4125a) containing the iOS 8.4 image and I copied this folder to the same path of the 7.0 beta. The path is the following:


When you will reopen Xcode 7 and choose your device, there will be an error message; just click on fix issue and that should do it!

This error occurs when the version of Xcode predates that of the device.

For example, attempting to run a build on a device running iOS 9.3 in Xcode 7.2 results in this error; Could not find Developer Disk Image.

Why an error message that actually describes what the hell is going on can't be provided is beyond me (Apple, I'm looking at you 👀).

Update to the latest version of Xcode through the App Store or via direct download to guarantee interoperability with connected iOS hardware.
