Cannot deploy share extension target app to iPhone 12 Pro - physical device. The error message shows, "The specified capability is not supported by this device." Works on Simulator as well as iPad Pro with the same beta version. What am I missing?

It appears that even on iOS 18 beta 4, the deployment of a share extension target to a physical device is broken. Has anyone seen the message, "The specified capability is not supported by this device"? Just a basic iOS app, no logic defined at this point. It builds fine. The main target gets deployed fine, only when attempting to deploy the share extension do I see this message. Works fine on a simulator, just not on physical device. iOS 18 beta 4, Xcode 16 beta 4 and MacOS 15 beta.
