how to set data for multiple UIpickerviews in Swift?

I have uiviewcontroller with uitextfields, when users tap on the textfields uipickerview appears as shown in the attachment. How can I make multiple uipickerview? For example, when the user tap on the countries textfields a pickerview shows up with countries array data and when users tap on the gender textfields uipickerview shows the genders array data and so on. I tried but only able to do it for one array which is countries as shown in my code. would appreciate if you could show me how to do it for the rest of my uitextfields.

thanks.

var countries = ["USA","UK","Spain" ]

var gender = ["Male","Female","Both"]

var language = ["English","French","Spanish","Other"]


override func viewDidLoad() {
super.viewDidLoad()


    var pickerView = UIPickerView(frame: CGRectMake(0, 200, view.frame.width, 100))

    pickerView.backgroundColor = .whiteColor()

    pickerView.showsSelectionIndicator = true


    var toolBar = UIToolbar()
    toolBar.barStyle = UIBarStyle.Default
    toolBar.translucent = true
    toolBar.tintColor = UIColor(red: 76/255, green: 217/255, blue: 100/255, alpha: 1)
    toolBar.sizeToFit()

    pickerView.delegate = self
    pickerView.dataSource = self
