How to set delegate or selection changed method?

Here is how I had accomplished this task...

1. Add a protocol to the top of SWSegmentedControl.swift file:

public protocol SWSegmentedControlDelegate {
    func segmentControl(_segmentControl: SWSegmentedControl, didSelectSegmentAt index: Int)
}

2. Add a delegate property to the SWSegmentedControl:
   public var delegate: SWSegmentedControlDelegate!
3. Add this line of code to the bottom of didTapButton(_ button: UIButton):
   self.delegate?.segmentControl(_segmentControl: self, didSelectSegmentAt: self.selectedSegmentIndex)
4. Add this extension to the object that will delegate selections:

extension YourObject: SWSegmentedControlDelegate {
    func segmentControl(_segmentControl: SWSegmentedControl, didSelectSegmentAt index: Int) {
        // do things
    }
}

5. Finally set the delegate:

var segmentedControl: SWSegmentedControl {
   let sc = SWSegmentedControl(items: ["item1", "item2"])
   sc.delegate = self
   return sc
}
