I downloaded a brand new blank 10.2 project and tried to build the .ios project using the release iphone build profile and got the same above error.
When compiling the Xamarin.Forms app in Visual Studio for Mac on Big Sur 11.2.2. The following error occurs:
Visual Studio for Mac is fully updated. The phone I'm trying to run it on is an iphone 12 pro max on 14.4.
Visual Studio profile Debug | iPhone > My iPhone. Provisioning provide Automatic attached to our Apple Developer Account.
The application runs fine on a simulator of the same hardware.
