FoodTracker Tutorial - Tap Gesture

So I'm having issues with the tap gesture for the "Work with View Controllers" section of the tutorial.  I'm not getting the image picker to show up when i sumlate or run the app on an iPhone.  I think the code is right, because its nearly identical to the sample.  I've also rebuilt the app from the beginning of that section 4 or 5 times.  I'm pretty sure the @IBOutlet and @IBAction are correctly connected because they have the filled grey circles next to them, but for some reason it won't work.  However, I can correctly run the sample.  Can anyone think of some issues that might be throwing me off?

import UIKit
class ViewController: UIViewController, UITextFieldDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

     // MARK: Properties


    @IBOutlet weak var nameTextField: UITextField!
    @IBOutlet weak var mealNameLabel: UILabel!
    @IBOutlet weak var photoImageView: UIImageView!

    override func viewDidLoad() {
        super.viewDidLoad()

        // Handle the text field’s user input through delegate callbacks.
          nameTextField.delegate = self
    }


// MARK: UITextFieldDelegate
    func textFieldShouldReturn(textField: UITextField) -> Bool {

          // Hide the keyboard.

        textField.resignFirstResponder()
        return true
    }

    func textFieldDidEndEditing(textField: UITextField) {
        mealNameLabel.text = textField.text
    }


    // MARK: UIImagePickerControllerDelegate
    func imagePickerControllerDidCancel(picker: UIImagePickerController) {
          // Dismiss the picker if the user canceled.
           dismissViewControllerAnimated(true, completion: nil)
    }

    func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {

          // The info dictionary contains multiple representations of the image, and this uses the original.
          let selectedImage = info[UIImagePickerControllerOriginalImage] as! UIImage
          // Set photoImageView to display the selected image.
           photoImageView.image = selectedImage
          // Dismiss the picker.
          dismissViewControllerAnimated(true, completion: nil)
    }


     // MARK: Actions
     @IBAction func selectImageFromPhotoLibrary(sender: UITapGestureRecognizer) {

          // Hide the keyboard.
          nameTextField.resignFirstResponder()
          // UIImagePickerController is a view controller that lets a user pick media from their photo library.
          let imagePickerController = UIImagePickerController()
          // Only allow photos to be picked, not taken.
          imagePickerController.sourceType = .PhotoLibrary
          // Make sure ViewController is notified when the user picks an image.
          imagePickerController.delegate = self
          presentViewController(imagePickerController, animated: true, completion: nil)
    }

    @IBAction func setDefaultLabelText(sender: UIButton) {
        mealNameLabel.text = "Default Text"
    }

}
