How to fix "Scrollable Content Size Ambiguity" in Xcode 11 (iOS 12, iOS 13) using Auto Layout
Disabling the content layout guides in size inspector (ruler icon) in properties
I was having the same issue, and by disabling the option it was gone.
Hope it helps! :)
I stacked with that problem as well. Found a good guide that helped me:

Basically what you need is 9 constraints (assuming you want to scroll only vertically):
1-4: ScrollView to Superview (top, bottom, leading, trailing). Make sure to connect it to parent view and not to safe area.
5-8: Content view to Content Layout guide (top, bottom, leading, trailing).
- Content view Width equals width to Frame Layout Guide.
I also encountered this problem (Version 11.0 beta 3 (11M362v)). I solved this problem by first setting the layout in xcode10 and then running it in xcode11. I haven't found any official instructions yet, proving that this is a problem with xcode11, but for now, I guess this is a problem with xcode11 bate.
