Sorry, I meant to say: "So all is now good." My iPad Mini 7 is now supported after installing Xcode 16.1.

I updated iPad Mini 7 to 18.1, My MacBook to 15.1, but those didn't fix. But then Xcode 16.1 just came out and after updating to 16.1, my iPad Mini 7 is now supported. It also gave me the simulator for my Mini 7. So all is not good. Too bad Xcode 16.1 wasn't available first.

I'm already on MacOS 15.0.1. I doubt this is a MacOS issue. This strikes me as a lack of Xcode support for the iPad Mini 7. I hope there's a solution soon.
