Subview loads but none of buttons work ios swift - ios

Question

I have a custom keyboard project with a Storyboard containing a collectionView and a scrollView. I also have a textField for a search bar that pulls up a nib containing a keyboard layout that I can use to search within the keyboard. When the subview containing the keyboard becomes active, I cannot press any of the buttons. I have tried bringing the subView to front upon becoming active and have tried sending the main view to the back when hiding the collectionView. What can I do to use the buttons in the subview?
Before viewDidLoad

{
isCaps = false
updateKeyBoard()

Please make sure the added subviews are userinteration enabled and it is not send to back in superview.
