This is a template for quickly building an iOS app in rust and swift. It uses cbindgen to build bindings.h for convenient rust-swift interop.

To use this with cargo-generate do:

cargo generate --git https://github.com/simlay/swift-rust-xcode-template.git --name myproject cd myproject ./rename.sh 

The ./rename.sh step renames the xcode stuff to match your project name.

To build the rest of the app/project you'll need to run:

• cargo install cargo-lipo
• rustup target add aarch64-apple-ios x86_64-apple-ios

After that you can build the app via the Xcode zoom-zoom-play button or run: xcodebuild -target myproject -configuration Debug -scheme my-test-app -sdk iphonesimulator13.2

Currently, there's some very rudimentary swift code that calls the rust with a closure passed in. You can see that code here.

Adding new things to this template is unfortunately annoying to add to or maintain because of the template tags in swift-rust-xcode-template.xcodeproj/project.pbxproj, rename.sh and Cargo.toml. This project is open to other work flows but here's what seems like the least worst option:

git clone https://github.com/simlay/swift-rust-xcode-template cargo generate --git ./swift-rust-xcode-template --name update-swift-rust-xcode-template cd update-swift-rust-xcode-template ./rename.sh 

modify your stuff and then cp the files back to the other directory.

I'f you're doing a lot of things you may want to symlink the src/lib.rs, swift-rust-xcode-template/*.swift, etc. to the swift-rust-xcode-template repo checkout.
