I got it.

Here's the solution:

It seems odd this code is needed at all. I would think that Apple would enable the desired behavior without having to write code for it. Perhaps there's a setting that does exactly what I need that I don't know about.

extension UIButton {
    open override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        super.touchesBegan(touches, with: event)
        next?.touchesBegan(touches, with: event)
        print("UIButton touchesBegan")
    open override func touchesMoved(_ touches: Set<UITouch>, with event: UIEvent?) {
        super.touchesMoved(touches, with: event)
        next?.touchesMoved(touches, with: event)
        print("UIButton touchesMoved")
    open override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
        super.touchesEnded(touches, with: event)
        next?.touchesEnded(touches, with: event)
        print("UIButton touchesEnded")
    open override func touchesCancelled(_ touches: Set<UITouch>, with event: UIEvent?) {
        super.touchesCancelled(touches, with: event)
        next?.touchesCancelled(touches, with: event)
        print("UIButton touchesCancelled")
    open override func touchesEstimatedPropertiesUpdated(_ touches: Set<UITouch>) {
        super.touchesEstimatedPropertiesUpdated(touches)
        next?.touchesEstimatedPropertiesUpdated(touches)
        print("UIButton touchesEstimatedPropertiesUpdated")
