Since the last thread (https://developer.apple.com/forums/thread/680614) was closed by accident, I will simply copy the same question below. I am trying to install an app which I am developing for testing on an iOS device. I get to the point where I need to sign, where I need to select a developer team to continue. I am doing this under "Signing & Capabilities" in Xcode 12.5. Using "Automatically manage signing": The "Team" field offers a drop-down menu which defaults to "None". Using the options from the drop-down menu i can pick the team I wish to use for signing, but on selecting the item from the list the choise keeps reverting back to "None", not allowing me to pick a team at all.  Not using "Automatically manage signing": The "Team" field is now static text, I can not change it from "None". Completing all the other fields leaves me with an error saying: "Signing for 'Runner' requires a development team. Select a development team in the Signing & Capabilities editor that matches the selected profile 'Provisioning Profile'." How do I select a team for signing an iOS app for debugging?
