Segmented Control returning wrong value?

Question

I have the following code:

@IBAction func didSelect(_ segmentIndex: Int) {
    switch segmentIndex
    {
    case 0:
        print ("1")

    case 1:
        // SHOWING THE PROFILE VIEW
        print ("2")

    default:
        print  ("break")
    }
}

I only have 2 tabs on the segment control, and whatever I click, it keeps printing "break". Why does that happen?

Answer 1

The parameter of an IBAction must be the type of the connected UI element.

So you have to pass UISegmentedControl and switch on its selectedSegmentIndex

@IBAction func didSelect(_ control: UISegmentedControl) {
    switch control.selectedSegmentIndex
    {
    case 0:
        print ("1")

    case 1:
        // SHOWING THE PROFILE VIEW
        print ("2")

    default:
        print  ("break")
    }
}
