title: Blank picker view in Swift
body: <p>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.</p>
  
  <p>My code is as follows:</p>
  
  <pre><code>import UIKit
  
  class LookingController: UIViewController, UIPickerViewDelegate {
  
      var iama=["dude","lady"]
  
      func numberOfComponentsInPickerView(pickerView: UIPickerView!) -&gt;Int{
          return 1
      }
  
      func pickerView(pickerView: UIPickerView!, numberOfRowsInComponent component: Int) -&gt;Int {
          return iama.count
      }
  
      func pickerView(pickerView: UIPickerView!, titleForRow row: Int, forComponent component: Int)-&gt;String!{
          return iama[row]
      }
  }
  </code></pre>
  
  <p>Any suggestions??</p>
