I found out that storyboards do not work on older versions of OS X, of which there are still a lot. What to use? XIB?

Question

Objective-C

NIB? custom code? What kind of animal is each of them?
Custom code, is it when they manually write code with NSWindow and so on in Swift?

Answer 1

I don’t know where you got the info from, but there were already storyboards in iOS6. Now even iOS7's market share is negligible. So make storyboards and don't worry.
