Use of unresolved identifier 'present' in Swift (Apple tutorial)

Question

I'm just following the official Apple introduction tutorial for Swift and Xcode by making a FoodTracker app. I've got this error (see title).

This is Xcode 7.2.1 I have imported UIKit

Here's the code I have where the issue appears. I have all class protocols and delegates and everything.

  @IBAction func selectImageFromPhotoLibrary(sender: UITapGestureRecognizer) {
    nameTextField.resignFirstResponder()
    // UIImagePickerController is a view controller that lets a user pick media from their 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
    present(imagePickerController, animated: true, completion: nil)
}

I would appreciate any help since I just started learning this language!

Answer 1

in your case (you are using xcode 7 -> swift 2) it has to be:

presentViewController(imagePickerController, animated: true, completion: nil)

right now you are using swift3 syntax.
