I've a many textfield and a pickerView with toolBar and it has a done button. My issue is I can't select the first row from the picker. While I have debugged in the didSelectRow but it won't run inside it. So please where would be my issue?

    var value = currentPickerArray[row]
    textFieldOutletArray[currentTag].text = value
}

@IBAction func doneBtn(sender: AnyObject) {

        var row = pickerView.selectedRowInComponent(0);
        NSLog("value L %d", row)
