Updating a device to iOS 11.2 breaks support with Xcode 9.1

Question

I tried to run my app on a device running iOS 11.2 and received the following error:

Could not locate device supported files.

Answer 1

It seems that Apple released iOS 11.2 to the public without releasing Xcode 9.2 yet (the Mac App Store reports 9.1 as latest at the time of this writing), which includes the iOS 11.2 SDK necessary to target devices running iOS 11.2. You should be able to run this on your device with the Xcode 9.2 beta, which you can download from the developer download page if you have a developer account

EDIT: Xcode 9.2 is publicly available now, and you can download it from the Mac App Store
