Overview
This tutorial teaches how to improve C library interoperability in Swift using annotations and wrappers. Swift provides annotations that transform C APIs into idiomatic Swift code without modifying the underlying C library implementation.
What You’ll Learn
- use Swift annotations on C headers to transform global C functions into Swift-style method calls
- apply reference counting annotations to automatically manage C library memory without manual release calls
- wrap unsafe C pointers in Swift types for better type safety and ergonomics
- create Swift-style error handling from C status codes using throws and Result types
- transform C naming conventions (prefixed global functions) into object-oriented Swift APIs
Prerequisites
Basic knowledge of Swift programming and C interoperability concepts
