objective-c
Objective-C
Objective-C is in maintenance mode. New features are rare, but it powers the Apple ecosystem's foundation. It allows mixing C++ (.mm) loosely.
When to Use
- Legacy iOS/macOS: Maintaining apps created before 2014.
- C++ Interop: Obj-C++ is often the bridge between C++ engines and Swift.
- Runtime Swizzling: Dynamic method replacement (used by Analytics SDKs).
Core Concepts
