2 simple "unresolved identitier" errors that I can't fix in Swift : <p>I am a Swift beginner currently following an Apple Intro to Developing iOS Apps in Swift tutorial. I have the follow error codes " Use of unresolved identifier 'UIImagePickerController' " and "Use of unresolved identifier 'imagePickController' " on lines 3 and 4 respectively. Thanks in advance! </p>

<pre><code>@IBAction func selectionImageFromPhotoLibrary(sender: UITapGestureRecognizer) {

    nameTextField.resignFirstResponder()

    let imagePickerController = UIIMagePickerController()

    imagePickController.sourceType = .PhotoLibrary

    imagePickerController.delegate=self

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


}
</code></pre>
