Setup

SwiftLint (optional)

SwiftLint analyses Swift code files for formatting style and coding conventions enforcement. Any warnings it generates are reported within Xcode.

It is automatically run as part of the build process in our Xcode project.

Installation using Homebrew:

brew install swiftlint

Configuration is done in .swiftlint.yml files. The main one is in the root of the project directory. There can be additional ones in sub-directories, such as DevelopingAccessibleAppsTests/.swiftlint.yml, which overrides some of the configuration for the unit test files.

The SwiftLint rules are available in a list with explanations and code examples.
