Swift Class Property Of Another Property

I have a question. How can I declare a property of a property in a class? (Not sure if that's how it's called but that's the analogy I think of)

Example: dog.legs.count or lightSwitch.status.turnedOn

How do I declare count or turnedOn as properties of legs/status?

And as a matter of fact, of what types do I declare legs and status considering that count and turnedOn are Int, respectively Bool?

It's not a great example of sensible composition, but:

class Legs {
    var count = 0
}

class Dog {
    var legs = Legs()
}

var dog = Dog()
dog.legs.count = 4

It is completely up to you:

Just create a class Legs or Status and add a property count resp. turnedOn to it. Assign an instance of those classes to the owning class.

Of course, accessing it means to include Legs and Status in the owning class.
