I'm on Xcode Version 14.2 (14C18). The project was created on the 12th, but I recently upgraded. When I try to add Google AdMob to my app. I get to the step in which: Update your Info.plist Update your app's Info.plist file to add two keys: A GADApplicationIdentifier key with a string value of your AdMob app ID (identified in the AdMob UI). A SKAdNetworkItems key with SKAdNetworkIdentifier values for Google (cstr6suwn9.skadnetwork) and select additional buyers who have provided these values to Google. from https://developers.google.com/admob/ios/quick-start#update_your_infoplist I save the changes to the file with an external editor but Xcode does not read them. P.S. Happy New Year!
