From 2 days ago... todays #SwiftAppDev dilemma: how to get SceneKit 3D controls and a couple of 2D ones (for which I could find no equivalent 3D ones) to be positioned properly together on the screen regardless of resolution changes. The conflict arises because 2D controls are tied to corner 0,0 while 3D controls are anchored to center point 0,0,0 and auto resize to fit the screen. 3D may be more complicated to envision, but is worth it for the flexibility and the broader range of possibilities.
