Indeed, I recall Storyboards were nice for a first layout, but constraints were iffy on the Storyboard, and in the end, a lot of more complex UIs just had to be written programatically. I remember around maybe 2013?, there was a UI component that was all the hype; the sliding options menu (where you hit the hamburger at the top and the menu would cover half the screen). I wanted to remake it and tried to do it with Storyboards and imperative code, but it never worked just quite right. When I got rid of the sliding menu UIView on the Storyboard and just wrote the UI programmatically via UIKit, it was hard to learn but the final product was a finely, tunable sliding options menu view :-)
