Quick & automatic setup

The easiest way to setup the dependencies of the project and generate the Xcode project is to run sh scripts/ from the top of the repository, before opening the project in Xcode.

Dependency Management - Carthage

We currently use Carthage for dependency management. New to Carthage? Others have found the following resources helpful:

Before opening the project in Xcode, run brew install carthage

carthage bootstrap --platform iOS --cache-builds

To generate the Xcode project run sh scripts/ In order to generate the Xcode project we use XcodeGen.


See the fastlane/ for a list and description of all lanes.

To launch a lane, you must have several env variable set. This can be done by creating a .env file in the fastlane folder, and fill it (see .env.example)

You can install Fastlane with Homebrew:

brew cask install fastlane

Roadmap on automatic screenshot generation:

Style and conventions - SwiftLint

A script runs when building the app that executes SwiftLint to enforce style & conventions to the code.

You can install SwiftLint with Homebrew:
