Wrong pin entry, snap a photo without presenting the camera on screen

Question

I am trying to have my application take a photo of an "intruder" when the wrong pin is entered into my application.

I have set up the UIImagePickerController(Below) and can make the application display the camera and take photos with no problem what so ever.

picker = UIImagePickerController() //make a clean controller
picker.delegate = self
picker.allowsEditing = false
picker.sourceType = UIImagePickerControllerSourceType.Camera
picker.cameraCaptureMode = .Photo
presentViewController(picker,animated: true,completion: nil)

Then i proceed to attempt this as to make the new set up for the picker

picker.showsCameraControls = false

I know that has to be set to false to call picker.takePicture()

Now I dont want to present the picker viewController and be able to call takePicture() but this is not hitting the delegate method of didFinishPickingMediaWithInfo.

I have tried using a custom overlay as well, but to no avail of 100% hiding the camera.

How do I go about not showing or displaying the camera on screen and being able to grab this picture of the front camera?

I have permission for access as well.

The other question posted on here of a similar topic does not solve this issue for help in swift.

Is the only way possible using AVFoundation? If so, any help would be appreciated

updated it so it is easier to see. The set up for picker happens. Then I want to be able to have an action or function call that will `takePicture()` but for now it has to present the viewController — A. Petrizza, Sep 10 '16 at 21:18
Check this out: http://stackoverflow.com/questions/28756363/how-to-capture-picture-with-avcapturesession-in-swift You can just hide the preview layer. — Bhavuk Jain, Sep 10 '16 at 21:24
Do you mean to not present the view controller? Or something else? — A. Petrizza, Sep 10 '16 at 21:27
Is this the only way to not show the camera and have the image be taken? — A. Petrizza, Sep 10 '16 at 21:31
Can you show me what to exclude entirely? Is it just the preview layer? Any help on this would be great, I am not too familiar with AVFoundation — A. Petrizza, Sep 10 '16 at 21:39
