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.
