Maybe you’re still using Xcode 7 because you’re not used to the new fonts in Xcode 8 and don’t like being a guinea pig. However, every time the phone upgrades the system, there will be a “Could not find Developer Disk Image” problem in the reality test.

# Solutions

  • Go to Finder -> Applications -> Xcode

  • Content –>Developer–>Platforms–> iphoneos. platform–>DeviceSupport

  • Put your missing Disk Image version in

I downloaded Xcode 6/7/8 and copied the disk image of the entire system for you. Many resources on the Internet are annoying, or they can not be downloaded, or they are charged.

If you are currently using Xcode 8 and want to run Xcode 7.0 +, there is no need to download Xcode 7 to solve this problem. The solution is as follows :(with every update to Xcode, fruit will discard the lowest iOS version.

  • Import disk image (7.0 or 7.1) into Xcode

  • Find Xcode(display package Contents) — >Developer — >Platforms — > iphoneos.platform — >Developer — >SDKs — > iphoneos.sdk Right-click “Show Introduction” and set permissions to “Read and write “.

  • Once permissions are set, go to the folder and find the ‘sdksettings. plist’ file and set the’ read and write ‘permissions (same as above).

  • Open the ‘sdksettings. plist’ file and find the array DEPLOYMENT_TARGET_SUGGESTED_VALUES, and’ Add row’ to add the appropriate version.

  • After restarting Xcode, please start your show ~~

  • Finally, don’t forget to change ‘read and write’ back to ‘read only ‘.

Any suggestions or comments you can keep ~ thanks ~
