iOS 16 has been released, and this article analyzes the percentage of Apple's built-in apps that use Objective-C, Swift, SwiftUI, and C and C++.

By comparing the various systems from iPhone OS 1 to iOS 16, we can draw some conclusions:

• Objective-C is at the core of iOS and is used directly or indirectly by most apps

• Swift’s usage has increased quickly over the past iOS versions. This year Swift finally surpassed C++

• The use of C++ is stable over the years

• SwiftUI starts to be noticeable which is a great sign: Apple is doing some dogfooding

• C is slowly but surely fading away
