Has anyone found the solution or cause of this?

Here is my code and I've tried switching the order of line 5 to before line 9

@IBAction func takePhoto(sender: UIButton) {
       
        let imagePicker: UIImagePickerController! = UIImagePickerController()
        imagePicker.delegate = self
       
        if (UIImagePickerController.isSourceTypeAvailable(.Camera)) {
            if UIImagePickerController.availableCaptureModesForCameraDevice(.Front) != nil {
                imagePicker.allowsEditing = false
                imagePicker.sourceType = .Camera
                imagePicker.cameraCaptureMode = .Photo
                imagePicker.cameraDevice = .Front
                presentViewController(imagePicker, animated: true, completion: {})
            } else {
                print("Camera not found")
            }
        } else {
            print("Application cannot access the camera.")
        }
    }
