I have a flutter app which runs perfectly in Android and I runned it on iOS in the past. But now when I try to do 'flutter run' in an iPad it throws this error:

I've the same issue this morning when installing the apps to iPad. The issue was due to the Signing & Capabilities not being proper assigned in Xcode. I can install it to iPad after I assigning it properly in Xcode.

I get this same warning whenever I try to build an app (a macOS app) using xcodebuild when I have a locked iOS device connected to my machine.

Unlocking the device suppresses the warning in xcodebuild.
