Where can I download 2019 Release 2? (Xcode 11/iOS 13 compatibility?)
unless you are in the Beta program, you can’t as it has not been released yet
and if you are in the Beta program, you should already have that information
You are a pre-release tester. Go to the pre-release section of the forum. It is available there.
Or downgrade Xcode an continue with 2019 1.1
