call function from another class swift

I have one viewController that has two segment view. as the below pic shows I want to press refresh button (top left) and effect inside the segment viewColler in swift. enter image description here

i couldn't add refresh button inside the segmentViewController, so is there a way to call function from fristViewController to segmentViewController by pressing refresh button ? or via prepareForSegue func ? P.S: viewDidLoad get some information online, by pressing refresh button this shown data will be refreshed.

I handle the segment change value like this

@IBOutlet weak var segment1: UISegmentedControl!
@IBAction func indexChanged(sender: AnyObject) {
    switch segment1.selectSegmentIndex
    {
    case 0:
        firstView.hidden = false
        secondView.hidden = true
    case 1:
        firstView.hidden = true
        secondView.hidden = false
    default:
    break;
    }
}

I appreciated.

Somewhere in firstViewController, there must be a function which handles a tap on the segmented control (perhaps it's called valueChanged). If you add a property to firstViewController:

var activeSegmentViewController: segmentViewController

and keep track of which segmentViewController is the active one in the valueChanged function, you can use that property to call the function:

activeSegmentViewController.refresh()
