Apple Swift: Initialize a class in another class - ios

Question

I have some trouble to init() a class in another class.
I've been looking if I can find a solution in here but I wasn't able to.
If I write super.init() there comes another error because the function isn't existing.
I don't know where I have to initialize it.
I'd prefer to init the Address class in the open init from the Contact class but if I do so I can't access the Address class.
I think that it isn't a big mistake but I'm not able to find it.
open class Contact: Identifiable {
public var id: Int64?
var FirstName: String
var Name: String
var Phone: String
var Mail: String
var Birth: String
var News: Bool
open class Adress: Contact {
var Street: String
var Number: String
var PostalCode: String
var City: String
var Country: String // Error:'super.init' isn't called on all paths before returning from initializer
//If I add the Super.Init() there is an error because Super.Init() isn't existing and I don't know where to create it.
init(Street: String, Number: String, PostalCode: String, City: String, Country: String) {
self.Street=Street
self.Number=Number
self.PostalCode=PostalCode
self.City=City
self.Country=Country
}
}
public init(id: Int64, Firstname: String, Name: String, Phone: String, Mail: String, Birth: String, News: Bool) {
self.id = id
self.FirstName = Name
self.Name = Name
self.Phone = Phone
self.Mail = Mail
self.Birth = Birth
self.News = false
}
}

Technically you could do it this way:
class Contact: Identifiable {
public var id: Int64
var name: String
class Address: Contact {
var street: String
init(street: String, contact: Contact) {
self.street = street
super.init(id: contact.id, name: contact.name)
}
}
public init(id: Int64, name: String) {
self.id = id
self.name = name
}
}
let contact = Contact(id: 1, name: "name")
let address = Contact.Address(street: "street", contact: contact)
But maybe you want to model it in a way that a Contact has an Address:
class Contact: Identifiable {
public var id: Int64
var name: String
var address: Address
public init(id: Int64, name: String, address: Address) {
self.id = id
self.name = name
self.address = address
}
}
class Address: Identifiable {
var id: Int64
var street: String
public init(id: Int64, street: String) {
self.id = id
self.street = street
}
}
let address = Address(id: 1, street: "street")
let contact = Contact(id: 2, name: "name", address: address)
