A Rust crate plus build-time code generator that produces FFI bindings so Rust and Swift can call each other's code safely. It bridges high-level types such as String, Option, Result, structs and classes, and supports async functions and generics without hand-written C glue.

Use cases

• call Rust code from a Swift iOS app
• call Swift APIs from Rust
• generate FFI bindings between Rust and Swift
• share high-level types like String and Result across a Rust-Swift boundary
• embed a Rust core library into an iOS or macOS app
• replace hand-written C FFI glue with generated bindings

When to choose

• You are building an iOS or macOS app with a Rust core and want safe, ergonomic bindings
• You need to pass rich types (Option, Result, structs, classes, async) across the Rust-Swift boundary
• You want build-time code generation via swift-bridge-build or the CLI instead of maintaining FFI manually

When to avoid

• You need Rust interop with languages other than Swift, such as Kotlin or Java
• You require a 1.0-stable API or complete documentation, since the crate is still 0.1.x with a work-in-progress book
• You only need a thin, simple C-level FFI layer that you can maintain by hand
