I often hear iOS developers ask some variant of the same key question: “What’s the best way to develop a UI in iOS: through Storyboards, NIBs, or code?”
Answers to this question, explicitly or implicitly, tend to assume that there’s a mutually exclusive choice to be made, one that is often addressed upfront, before development.
