From 1 day ago... Inspiration struck to solve the latest #SwiftAppDev dilemma! I found an acceptable positioning of 3D and 2D controls with no need to reposition the 2D controls. That left finding a way to programmatically mimic the 3D resizing and apply it to their height. I finally struck upon the idea of subtracting a ratio of the total screen height to solve the issue. It held up well thru final testing. The upgrade to my productivity app went in to the apple app store and is now available.
