Why is Xcode 11.2.1 not appearing in the App Store updates tab? [duplicate]

I use OS X and have Xcode 11.2. I tried to push an app to TestFlight and got a warning that I needed to upgrade to Xcode 11.2.1. Every time that I've upgraded Xcode in the past, I went to the Updates tab in the App Store, and downloaded the version there if there were any.

Right now there's no version 11.2.1 in the App Store.

What I Want To Know:

1) If 11.2.1 exists, why isn't it in the Updates tab of the App Store? Is it only new major and minor versions, and not patch versions, that show up there?

2) What's the best way to get version 11.2.1?

Solution 1:

Xcode 11.2.1 GM seed is available at https://developer.apple.com/download/ after sign in.

I just started (and stopped) the download.
