While ObjC is far from dead, I’m not sure these metrics paint an accurate picture.

For a Swift-first app or binary, there are a few reasons that you might see ObjC as part of the binary:

- easier interop with ObjC

- Xcode code generation (CoreData, Intents, etc)

- legacy code (no real benefit to rewriting if it works fine with Swift)

I’d expect most Swift-first binaries to have even a small amount of ObjC for one of the reasons above. I’d also expect that binaries already containing ObjC would rarely drop it, even if new development is done in Swift.

Metal is a mix of Objective-C and C++, while most examples use Swift, they are actually bindings to the implementation.
