Developing for iOS 14 with Xcode 12.4

Oh boy, Apple….

I’m still running macOS 10.15.7 Catalina on my Mac due to different reasons. My iPhone is already up to date on iOS 14.5.

That means my Mac can only run Xcode 12.4 which makes it incompatible with my iPhone for development. But there is a way.

DeviceSupport files

You need an additional DeviceSupport file. Do the following:

  • Close Xcode
  • Go to
  • Download the matching zip in my case 14.5
  • Unzip the archive
  • Copy the folder to
    • /Applications/
  • Start Xcode
