Make an imagepickercontroller swipable?

It's only the previewImage (the freshly taken image) that can be swiped through each viewcontroller, but when the UIImagepickercontroller is present i cannot swipe and navigate between the different viewcontollers.
Please help :)

@danieldelouya I am not quite sure I follow what you are trying to do. Do you mean to have multiple UIImagePickerControllers that are adjoined that you can swipe between?

No only the one in the middle. Like snapchat.

I know it's within these lines of code:

    // 2) Add in each view to the container view hierarchy
    //    Add them in opposite order since the view hieracrhy is a stack
    self.addChildViewController(CVc);
    self.scrollView!.addSubview(CVc.view);
    CVc.didMoveToParentViewController(self);

    self.addChildViewController(BVc);
    self.scrollView!.addSubview(BVc);
    BVc.didMoveToParentViewController(self);

    self.addChildViewController(AVc);
    self.scrollView!.addSubview(AVc.view);
    AVc.didMoveToParentViewController(self);

Let's say BVc is a uimagepickercontroller with a camera interface. How do i make that one swipable? It only becomes swappable after I've taken a picture and see the picture on a UIImageView

I've tried this, but it didn't work:
self.addChildViewController(BVc);
self.scrollView!.addSubview(BVc.picker.view); // .picker
BVc.didMoveToParentViewController(self);
