Swift 3:

@IBOutlet weak var cameraContainerView:UIView!

var imagePickers:UIImagePickerController?

On ViewDidLoad:

override func viewDidLoad() {

        super.viewDidLoad()
        addImagePickerToContainerView()

    }

Add Camera Preview to the container view:

func addImagePickerToContainerView(){

        imagePickers = UIImagePickerController()
        if UIImagePickerController.isCameraDeviceAvailable( UIImagePickerControllerCameraDevice.front) {
            imagePickers?.delegate = self
            imagePickers?.sourceType = UIImagePickerControllerSourceType.camera

            //add as a childviewcontroller
            addChildViewController(imagePickers!)

            // Add the child's View as a subview
            self.cameraContainerView.addSubview((imagePickers?.view)!)
            imagePickers?.view.frame = cameraContainerView.bounds
            imagePickers?.allowsEditing = false
            imagePickers?.showsCameraControls = false
            imagePickers?.view.autoresizingMask = [.flexibleWidth, .flexibleHeight]

        }
    }

On custom button action:

@IBAction func cameraButtonPressed(_ sender: Any) {

         if UIImagePickerController.isSourceTypeAvailable(.camera){
            imagePickers?.takePicture()

         } else{

          //Camera not available.
        }  
    }
