OK. I've been able to get an opaque background by setting navigationBar.scrollEdgeAppearance to standardAppearance. Nevertheless I still can't understand why some navigation items default to opaque and other transparent.

Now that the Family Sharing is up and running for renewable subscriptions, can someone confirm here what are the values received for the original_transaction_id field in receipt. Our assumption from the doc is that all customers should get the same original_transaction_id value as the original purchaser, while each transaction_id is unique. Others here are expecting different original_transaction_id for each customers. And the accepted answer is ?

Same problem with XC12 GM. I tried to suppress DVTSourceControlAccountDefaultsKey from defaults with no success. Then I commented the [credentials] section in /Applications/Xcode.app/Contents/Developer/usr/share/git-core/gitconfig restarted Xcode and was able to access ONE repository, which recreated an entry in DVTSourceControlAccountDefaultsKey This repository is now operational. But any other is not, even if it use the same credential. It looks like Xcode 12 has a bug in managing MULTIPLE entries in that key.
