Usage

Our class or struct

We created the next Animal protocol:

protocol Animal {
    var name: String {get set}
    func say() -> String
}

After that we have the Dog struct:

struct Dog: Animal {
    var name: String
    
    init(name: String) {
        self.name = name
    }
    
    func say() -> String {
        "Guau Guau"
    }
}

Also we have the cat struct:

struct Cat: Animal {
    var name: String
    
    init(name: String) {
        self.name = name
    }
    
    func say() -> String {
        "Miau Miau"
    }
}

Then we have the struct PetOwner, we assign the values inside in PetOwner using the annotation @Inject

struct PetOwner {
    @Inject var dog: Animal
    @Inject var cat: Cat
}

Creating the modules

We created the demoModule Module:

let demoModule = module { container in
	container.factory { Dog(name: "Fido") as Animal}
	container.factory { Cat(name: "Tiger")}
}

Start Swin

We in the AppDelegate let's star Swin

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
	Swin.modules(demoModule)
	Swin.start()
   /* some code */
   return true
}
