How to get one class from two different classes in Swift based on API level?

Question

I want to use a library with the SwipeTableViewCell class (obtained from UITableViewCell), but it only supports iOS 9, so I want to extract from this class, if possible, but from the regular UITableViewCell class, if the application runs below 9.0.

This is the best I could come up with (doesn't work):

@available(iOS, obsoleted: 9.0)
class MyTableViewCell : UITableViewCell {
}

@available(iOS 9.0, *)
class MyTableViewCell : SwipeTableViewCell {
}

Then I try to extract from this class:

class SomeOtherTableViewCell : MyTableViewCell {
}

Xcode gives me the following error and links to the two class definitions above:

SomeOtherTableViewCell.swift:34:31: 'MyTableViewCell' is ambiguous for type lookup in this context

What a cool way in Swift to conditionally infer from two different classes depending on the API level?

    override func viewDidLoad() {
        super.viewDidLoad()

        if staticCell is SwipeTableViewCell {
            print("This class was converted magically, which means we're on iOS 9 or later")
        }
    }
}

class SwipeTableViewCell: UITableViewCell {
    // Standin for your library class
}

class MySwipeableCell: UITableViewCell {

    override func awakeAfter(using aDecoder: NSCoder) -> Any? {
        if #available(iOS 9, *) {
            // This will replace the MySwipeableCell with an instance of SwipeTableViewCell instead
            return SwipeTableViewCell.init(coder: aDecoder)
        }

        return self
    }
