title: IBAction func on button not triggering
body: <p>I have 3 buttons in a VC, all hooked up to IBAction functions. Two of them work fine but the Submit button simply simply won't trigger. </p>
  
  <p>I have made sure User Interaction is enabled. I have also tried adding sender: AnyObject as a parameter and re-hooking up the function to the button but still no luck. I have also cleaned the project. I am very baffled as to what is going on.</p>
  
  <p>Here is how the VC looks:

  <p>Here is the code for each IBAction func:</p>
  
  <pre><code>@IBAction func captureImage(){
      self.saveVideoVar = false
      let imageFromSource = UIImagePickerController()
      imageFromSource.delegate = self
      imageFromSource.allowsEditing = false 
  
      //if there is a camera
      if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera){
          imageFromSource.sourceType = UIImagePickerControllerSourceType.Camera
          self.presentViewController(imageFromSource, animated: true){}
      }
      else{
          let title = "Error"
          let message = "Could not load camera"
  
          let alert = UIAlertController(title: title, message: message, preferredStyle: .Alert)
          alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.Cancel, handler: nil))
          presentViewController(alert, animated: true, completion: nil)
      }
  
  }
  
  @IBAction func openImageLibrary(){
      self.saveVideoVar = false
      let imageFromSource = UIImagePickerController()
      imageFromSource.delegate = self
      imageFromSource.allowsEditing = false
  
      imageFromSource.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
  
      //presents (loads) the library
      self.presentViewController(imageFromSource, animated: true){}
  }
  
  //code to submit image and video to amazon S3
  @IBAction func submitToS3(){
  
      print("x")
  
  
      if let img : UIImage = imageView.image! as UIImage{
          let path = (NSTemporaryDirectory() as NSString).stringByAppendingPathComponent("image.png")
          let imageData: NSData = UIImagePNGRepresentation(img)!
          imageData.writeToFile(path as String, atomically: true)
  
          // once the image is saved we can use the path to create a local fileurl
          let url:NSURL = NSURL(fileURLWithPath: path as String)
          nwyt.uploadS3(url)
  
      }
  
  }
  </code></pre>

  <p>OH MY GOD! I feel stupid. There was a duplicate screen I had forgotten to delete that looked exactly the same but wasn't the one that was being displayed. I'm going to delete this in an hour. Below was the problem:</p>
