How do i get rid of xib after presenting it? - swift

Question

I am creating my own UIImagePicker Overlay and am using a Xib in order to display the overlay. Whenever I present the imagepicker, it seems to present twice, once when I call the main bundle to load the nib and the other when I explicitly present the imagepickercontroller. The main problem i'm having is when I dismiss the imagepickercontroller, the first one goes, which is great, but the underlying view of the xib still remains and doesn't go regardless of what i do.
I tried to convert the Objective-C example project for how to create a custom uiimagepickercontroller Apple has on their website into Swift. I'm not sure what I"m doing wrong, here is my code:
func showImagePickerForSourceType(sourceType: UIImagePickerControllerSourceType) {
let picker = UIImagePickerController()
picker.modalPresentationStyle = UIModalPresentationStyle.CurrentContext
picker.sourceType = sourceType
picker.delegate = self
if sourceType == UIImagePickerControllerSourceType.Camera {
//gets rid of the out of the box imagepicker
picker.showsCameraControls = false
//loads the overlay xib for the camera
NSBundle.mainBundle().loadNibNamed("OverlayView", owner: self, options: nil)
self.overlayView.frame = (picker.cameraOverlayView?.frame)!
picker.cameraOverlayView = self.overlayView
self.overlayView = nil
//makes the image capture screen the full screen size
let screenSize: CGSize = UIScreen.mainScreen().bounds.size
let cameraAspectRatio: Float = 4.0 / 3.0
let imageWidth:Float = floorf(Float(screenSize.width) * cameraAspectRatio)
let scale: Float = ceilf((Float(screenSize.height + 120) / imageWidth) * 10.0) / 10.0
picker.cameraViewTransform = CGAffineTransformMakeScale(CGFloat(scale), CGFloat(scale))
}
self.imagePickerController = picker
self.presentViewController(self.imagePickerController, animated: true, completion: nil)
}
Here is the code for a button on the xib dismissing the view. How can i fix this? Because i'm printing out the array of view controllers on the navigation stack, and it only shows one.
#IBAction func goBack(sender: AnyObject) {
self.imagePickerController.dismissViewControllerAnimated(true, completion: nil)
}

It sounds like you have your view controller's view outlet connected to the view in your .xib file in addition to the overlayView outlet. This would probably cause what you're describing.
