Improving the usability of C libraries in Swift
Summary
This Swift blog post uses WebGPU as a case study to show how to make C libraries safer and more ergonomic in Swift without editing the C headers. It covers techniques like API notes, module maps, SwiftName, SWIFT_SHARED_REFERENCE, and Swift import strategies to create Swifty interfaces and better memory safety. It also discusses tooling, nullability, and future improvements to header design to reduce annotation effort.
