"Could Not Find Developer Disk Image"

Xcode error Could not find Developer Disk Image

I am facing the same issue on Xcode 7.3 or Older version of your Xcode and my device version is iOS 10 or newer version of your OS.

This error is shown when your Xcode is old and the related device you are using is updated to latest version.

We can solve this issue by following the below steps:

Method 1:-

• Right click on Xcode 7.3 or version of your Xcode, now select "Show Package Contents", "Contents", "Developer",
  "Platforms","iPhoneOS.Platform", "Device Support".

• Now check there is latest version of developer disk image(folder) like 12.1 or newest version(folder) in your case. Copy the latest
  version and Paste in the same Folder Device Support.

• In my case I have 12.1 is the latest folder. Now it will generate the copy of that version like 12.1 copy or newest version(folder)copy
  in your case.

• Now Change the name of copy folder to your latest version of iPhone like. In mine case, I have 12.1(Folder)copy and rename it into 12.4. As you can see in the above screenshot. You can change it according to your latest version of phone. I need it for 12.4 so i just rename the folder to 12.4.

• Now your Xcode has a new developer disk image. Close the finder now,
  and quit your Xcode. Open your Xcode and the error will be gone. Now
  you can connect your latest device to old Xcode versions.

                        **OR**
  

Method 2:-

First of all, download the latest Xcode Version. No Need to install the latest Xcode.

We can solve this issue by following the below steps:

• Right click on Xcode 8 or Newer version of your Xcode, select "Show Package Contents", "Contents", "Developer",
  "Platforms", "iPhoneOS.Platform", "Device Support"
• Copy the 10.0 folder (or above for later version).
• Back in Finder select Applications again
• Right click on Xcode 7.3 or version of your Xcode, now select "Show Package Contents", "Contents", "Developer", "Platforms",
  "iPhoneOS.Platform", "Device Support"
• Paste the 10.0 folder (or above for later version).

Now your Xcode has a new developer disk image. Close the finder now, and quit your Xcode. Open your Xcode and the error will be gone. Now you can connect your latest device to old Xcode versions.

Xcode error “Could not find Developer Disk Image” 10.3.1 Fix?

I don't think Apple has ever released the developer disk images separately so I can't imagine they would in the future.

Solving the download problem is probably easier, don't use App Store because it's fairly miserable about downloading on a bandwidth limited connection but instead visit https://developer.apple.com/download/more/. They have the actual files hosted there so you can get them with a more appropriate tool, you'll know they're definitely from Apple as well.
