Hi, I have been working through some of the SwiftUI tutorials (I really like it so far). Today I was editing a source file and I decided to widen the window a bit. I dragged too far to the right and wound up hiding the Preview. I cannot find any menu item, preference, etc. that allows you to show/hide the Preview. I'd like to get it back but have no idea how. I tried deleting some Xcode preferences but that did not help. I appreciate any advice. This is for Xcode 12.1.
