Thanks for the help! Some feedback: I'm not sure if "Document Tab" is the official name of these or not. That's what they're called in the "Introducing Xcode 12" page but I don't see them called that in Xcode itself. It would be nice if there was a visual difference between a regular tab and a tab that contains document tabs? In fact the whole notion that a Document Tab is a tab and it contains tabs. and finally: 3. I would like to make the whole thing always use document tabs. i.e. One tab per file unless I choose to open a duplicate tab. I can't tell you how many times I've accidentally had 5 tabs open to the same file and no tabs open to the file I had been recently working on.

I guess I can't edit my own post? Meant to say: the whole notion that a Document Tab is a tab and it contains tabs is confusing

Ugh. So the customer had spelled the app name wrong. Sorry to have wasted everyone's time.

@adamglo Did that manage to fix things for you? I'm sitting here waiting 3-4 minutes every time I make a minor text change and it's killing me.

I'm getting the same thing when I try to upload a build to ASC. I've had bitcode disabled for a long time and have had no problem making builds as recently as last week. I can barely find any information on what to actually do to resolve this error. The only thing that came close was some Stack Overflow posts about using .NET Maui
