Answer 1

I had a similar problem when i had a subViewController with buttons and tapHandlers to match, and I wanted to place this to a stack in a separate superViewController..

This cause none of the tapHandlers to to trigger, and the solution was to instead of only using addArrangedSubview(subViewController.view), I also used addChildViewController(subViewController) in the superview to allow the childViewController to continue to operate as a viewController and not just a view.
