Here is how:

```Swift

for object in objects {
    switch object {
    case let object as Subclass1:
        doSomethingWith(object)
    case let object as Subclass2:
        doSomethingWith(object)
    case let object as Subclass3:
        doSomethingWith(object)
    default:
        break
    }
}

```
