Setup the iOS Build Environment

Prepare your build environment

  1. Install Xcode 15.0 or higher.
  2. Ensure you have Python 3 installed: brew install python
  3. Install linting and formatting tools: brew install swiftlint
  4. (Optional, only required for building on the CLI) Install xcpretty: gem install xcpretty

Setting up Rust

Rust can be installed using rustup, with the following commands:

  • curl https://sh.rustup.rs -sSf | sh
  • rustup update

Platform specific toolchains need to be installed for Rust. This can be done using the rustup target command. In order to enable building to real devices and iOS emulators, the following targets need to be installed:

rustup target add aarch64-apple-ios x86_64-apple-ios aarch64-apple-ios-sim

Building

This should be relatively straightforward and painless:

  1. Ensure your repository is up-to-date.
  2. Ensure Rust is up-to-date by running rustup update.
  3. Run a build using the command make build-swift
    • To run tests use make test-swift

The above can be skipped if using Xcode. The project directory can be imported and all the build details can be left to the IDE.
