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 and macOS Codebase Maintenance: Maintaining established Apple applications built before Swift.
C/C++ and Swift Bridging (Objective-C++): Acting as a high-performance interoperability bridge between native C++ engines and modern Swift.
Dynamic Runtime Introspection: Leveraging the dynamic Objective-C runtime for method swizzling and dynamic message forwarding.
High-Performance Audio & Core Audio Frameworks: Interfacing with low-level Apple media frameworks where C pointer interop is required.
