Swift: different objects in one array?

Question

Is there a possibility to have two different custom objects in one array?

I want to show two different objects in a UITableView and I think the easiest way

Answer 1

Depending on how much control you want over the array, you can create a protocol that both object types implement. The protocol doesn't need to have anything in it (would be a marker interface in Java, not sure if there is a specific name in Swift). This would allow you to limit the array to only the object types you desire. See the sample code below.

protocol MyType {

}


class A: MyType {

}

class B: MyType {

}

var array = [MyType]()

let a = A()
let b = B()

array.append(a)
array.append(b)
