list of countries into uipickerview swift 3

Question

I googled how to find the list of the countries and trying to implement into PickerView, but I am stuck at this point where I try to do countries.count

Answer 1

You need to return array count in method numberOfRowsInComponent and in the titleForRow you need to return array object, show that it will show in picker.

func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
    return countries.count
}

func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
    return countries[row]
}
