ObjectMapper - Initialize an empty init in child class

Question

I have a base class called "Base" that implements the Mappable protocol. I already subclassing that class as described below.

class Base: Mappable {
    var base: String?

    required init?(map: Map) {

    }

    func mapping(map: Map) {
        base <- map["base"]
    }
}

class Subclass: Base {
    var sub: String?

    required init?(map: Map) {
        super.init(map: map))
    }

    override func mapping(map: Map) {
        super.mapping(map: map)

        sub <- map["sub"]
    }
}

Is it possible to create an empty init in subclass that how i can create an instance of subclass like this?

var obj = Subclass()

Answer 1

You can add init() inside your Base and override init() inside your SubClass

class Base: Mappable {
    var base: String?

    init() {}

    required init?(map: Map) {

    }

    func mapping(map: Map) {
        base <- map["base"]
    }
}

class Subclass: Base {
    var sub: String?

    override init() {
        super.init()
    }

    required init?(map: Map) {
        fatalError("init(map:) has not been implemented")
    }

    override func mapping(map: Map) {
        super.mapping(map: map)

        sub <- map["sub"]
    }
}
