Apple's use of Swift and SwiftUI in iOS 17
What is interesting to me is the decline in C, from 52% in iPhone OS 1 to 5% in iOS 17.<p>I am a bit surprised to see Objective-C still dominating. It goes to show that transitioning languages is extremely difficult, even when you are applying the impetus to yourself. Consider the Python 3 transition in this light. Python 3 came in 2008 and I don't think it could be said the transition completed prior to 2020, so 12 years conservatively. Swift picks up in iOS 10 at 1%. So, perhaps one could estimate by iOS 22 some large majority of Swift in Apple codebases? And then maybe by iOS 30 Objective-C is down to 5% or les?
