New Versions of iOS with Old Versions of Xcode

Developer 1 Minute

I found myself in a predicament at the gig. I updated my iPhone 12 Pro to iOS 16 but wasn’t able to debug the app in Xcode 13 tethered to the MacBook.

During iOS 16 beta period, a brave teammate tried to compile the app in Xcode 14 on their personal Mac and there were build errors we weren’t ready to address at the time.

So how could I debug the app on a device I was dependent on before?

The solution was to:

  1. Close Xcode 13
  2. Copy this directory from a Mac with Xcode 14 installed /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/
  3. Open Xcode 13 again.
