Answer 1

It seems your issue is related to this: SE-0103

Try chaging the method header of your addButton(_:action:) to:

public func addButton(_ title:String, action:@escaping ()->Void)->SCLButton {

The diagnostic messages from new betas are so confusing and inadequate as usual, but making your property simply non-Optional var action:()->Void = {} will give you a little more useful info.
