How does it work?

[SubZane]

I just wondered I can get it to work? (Using Swift 5) Some more documentation would be helpful.

• The example cannot compile due to "No such module Snapkit" (I've run pod install and followed the instructions as best as I can)
• The documentation doesn't help much. The code from the example is different from the example in readme, cannot get either to work at all
• Using the example from the readme returns "Thread 1: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)" on line 57 in SmoothPickerView.swift
• Is SmoothPicker a subclass of UIView or UIViewPicker? What controller should I create in the storyboard?
