I have a Xamarin.Forms app. It works great on Android Emulator and Android Devices, It also works on iPhone Simulator but I hacve not been able to get it to work on a physical iPhone Device. I have attached my output log below.
========== Deploy: 0 succeeded, 0 failed, 0 skipped ==========
The app myapp.iOS is already deployed on mkimonos’s iPhone

Have you followed this doc to set up your certificate and provisioning profile?
https://docs.microsoft.com/en-us/xamarin/ios/get-started/installation/device-provisioning/free-provisioning?tabs=macos
Manual provisioning:
https://docs.microsoft.com/en-us/xamarin/ios/get-started/installation/device-provisioning/manual-provisioning?tabs=macos
If you didn't use the correct code signing the app can't be deployed on a real physical device.
You are missing Provisioning Profile
Also you need to add the device into Developer portal in order to run it on device.
