Blank picker view in Swift

I am pretty new to programming and I am trying to insert a picker view. I think my code is right, but when I build the app it is blank. I have no idea what I am doing wrong.

My code is as follows:

import UIKit

class LookingController: UIViewController, UIPickerViewDelegate {

    var iama=["dude","lady"]

    func numberOfComponentsInPickerView(pickerView: UIPickerView!) ->Int{
        return 1
    }

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

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

Any suggestions??

I think you forgot to add pickerView into your view so follow this step.

Go to the Storyboard, drag a Picker View from the Object Library to the top of the View Controller inside the Storyboard.

The Storyboard should look like this.

enter image description here

The Picker View must conform to the UIPickerViewDataSource and UIPickerViewDelegate protocol. Ctrl-click the Picker View and drag from the dataSource Outlet to the View Controller in the Document Outline. Repeat this step for the delegate Outlet.

enter image description here

May be this will help you.
