Bevy iOS crates drop their separately shipped Swift packages

rustunit.com 5 min read Editor score 6/10

The crates replaced several hand-built Swift or Objective-C bridges and related package setups with installation through Cargo. The example shows how platform boundaries can add maintenance and distribution costs to cross-language libraries.

What: Bevy iOS crates replaced separately shipped Swift packages with Rust bindings using objc2 and generated framework bindings.
How: objc2 binds Apple’s Objective-C frameworks dynamically; Rust can call UIKit APIs and define Objective-C delegate classes for callbacks.
Why it matters: This removes a separate SPM install and version match, plus per-release .xcframework packaging, from these crates.

Rust uses objc2 bindings to call Apple frameworks and receive delegate callbacks. Sketched from the article's own text.
