Dependency injector Swift. Compatible for swift server-side and swift for iOS
First you must create a Module and register some providers
let module = Module()
module.bind(IAnimal.self).to(Dog.self)
IAnimal is a protocol that MUST be implemented by the Dog class
public protocol IAnimal {
var name: String { get }
func scream() -> String
}
open class Dog: IAnimal, Injectable {
public var name: String
public required convenience init(injector: Injector, arguments: [String : Any]?) throws {
self.init(name: arguments?["name"] as? String ?? "Athina")
}
init(name: String) {
self.name = name
}
public func scream() -> String {
return "Barking"
}
}
After that, you must register your module inside an injector
Injector.default.register(module: module)
Finally, inject an IAnimal and retrieve a concrete class registered inside your module
if let animal = try? Injector.default.inject(IAnimal.self) {
print(animal.name) // print Athina
print(animal.scream()) // print Barking
}
Register a provider that handle arguments :
let module = Module()
module.bind(IAnimal.self).with { (_, arguments) -> IAnimal? in
if let name = arguments?["name"] as? String {
return Dog(name: name)
}
return nil
}
Injector.default.register(module: module)
Inject an IAnimal with arguments Dictionary<String, Any> :
if let animal = Injector.default.inject(IAnimal.self, arguments: ["name": "Athina"]) {
print(animal.name) // print Athina
print(animal.scream()) // print Barking
}
if let otherAnimal = Injector.default.inject(IAnimal.self, arguments: ["name": "Yoda"]) {
print(otherAnimal.name) // print Yoda
print(otherAnimal.scream()) // print Barking
}
