Hi there,

My app uses UIScreen.screens.count (deprecated) to predict whether mirroring is happening on older iOS devices

I noticed that the number of screens is different between iOS 26 SDK apps, and iOS 27 SDK apps.

Can I expect that iOS 26 SDK apps will continue to return 1 screen like below for the iPhone Duo release?. I assume it's like this is to maximise compatibility.

App built with SDK 26 on Xcode 27.1b1 iPhone Duo sim:

UIScreen.screens.count == 1

App built with SDK 27 on Xcode 27.1b1 iPhone Duo sim:

UIScreen.screens.count == 2

Thanks for the help! Sam
