Part 3: Common macOS/iOS specific instructions

FRB Template App: Applying the modified Workflow.

Common macOS and iOS steps

An common step for macOS / iOS is needed: creating an Xcode project inside of the Rust library project folder (rust/). This can be done using the cargo-xcode command.

This Cargo subcommand is used to generate all Xcode project files for Rust projects. It will also create a build rule that will be used to create a dynamic and a static library from the Rust library code in Xcode's build step. If you don't remember, take a look back and read the section Xcode Essentials.

To install the cargo-xcode command use:

cargo install cargo-xcode@1.5.0

After the installation of the command, create the Rust Xcode project. Make sure to be in the rust/ directory. From the project's root folder you may switch into the right directory:

cd rust

cargo xcode

cd ..
