Summary
This article discusses how to improve the usability of C libraries when used in Swift programming. It explains that while Swift provides direct interoperability with C, using C libraries directly can feel out of place in Swift code. The article covers techniques for creating more Swift-friendly interfaces to C libraries, including wrapping C APIs with Swift types, handling C pointers and memory management in a Swift-idiomatic way, and creating more natural Swift APIs that hide C-specific details while maintaining performance.
Key quotes
· 4 pulledWhile one could go and rewrite these libraries in Swift, usually there is no need, because Swift provides direct interoperability with C.
When you use a C library directly from Swift, it will look and feel similar to using it from C.
That can be useful if you're following sample code or a tutorial written in C, but it can also feel out of place.
With a little setup, you can directly use existing C libraries from your Swift code.
