StaticGC

Apple's replacement for Objective-C — the primary language for iOS, macOS, and Apple platform development. Combines protocol-oriented design with strong type safety and optionals. Benchmarks show moderate conciseness with strong safety; concept distribution leans toward types and OOP, reflecting its protocol-heavy design.
