Hands-On Design Patterns with Swift

Automatic Storyboard Injection

A really handy extension is the SwinjectStoryboard plugin, which adds Automatic Storyboard Injection to Swinject:

extension SwinjectStoryboard {    class func setup() {        defaultContainer.storyboardInitCompleted(WeatherTableViewController.self) { r, c in            c.weatherFetcher = r.resolve(WeatherFetcher.self)        }        defaultContainer.register(Networking.self) { _ in Network() }        defaultContainer.register(WeatherFetcher.self) { r in            WeatherFetcher(networking: r.resolve(Networking.self)!)        }    }}

The SwinjectStoryboard class inherits from UIStoryboard and lets us inject all the dependencies in the view controllers defined in the storyboard. If the setup() class function is present, it will be called during the setup of the app, and ...
