Hi, Unfortunately, it didn't worked for me. I added the iOS 14.5 device support file into the Xcode app, but after the build and run, I got the following message: "Failed to prepare device for development". (iOS 14.5 release, Xcode 12.4 (12D4e)) And the weird thing is, in Xcode the maximum iOS deployment target can be only up to 14.4 MicheleC's instructions were simple, I think I followed it right. So, I don't understand what is the problem. Can I ask your opinion, please?
