Xcode 12 4 Unsupported OS version after iPhone iOS update 14 7

0 votes

After updating iPhone iOS version to 14.7+, Xcode 12.4 can no longer build to that iPhone device.

In Xcode when choosing a Build Destination (Product > Destination > [device] or from the UI dropdown shown below) the newly updated iPhone will have beside it (unsupported OS version):

xcode build destinations dropdown

iPhone listed with "(unsupported OS version)".

Can't Upgrade to Big Sur / Xcode 12.5

I'm stuck on Mac OS Catalina (old hardware) and cannot upgrade to Xcode 12.5 which requires Big Sur.

How can we add/update device support to Xcode to build to an unsupported iPhone version (iOS 14.7+)?
