I have implemented reusable button component using combination of .xib and cocoa class following this guide

It works, but there is an issue. In order to use it in one of my main View Storyboards I have to first drag in a normal view (referenced as superview in question title) and then apply my Button class, to make it a button.

This works, but initial view height and width alongside its white background persist, so I have to always manually rewrite those when I use my component, which in itself results in poor reusability.

Ideally, I'd like to drag in a view, set it to Button class and thats it, that view should instantly take buttons height and width and have transparent background. Is something like this achievable?

To light more context on this issue here are few useful bits of my implementation

1. Reusable component made as a .xib view and its own cocoa class

2. Contents of Button.swift
