very nice :) i'm feeling that we commented out all the sdWebImage placeholder calls anyway :) a few issues thou: 1. when saving user profile with less than 3 photos, we are saving imgUrl2 and 3 with empty String "", which is generating extra bars and "empty swipes" 2. please bring back the pagination. 3. at the beginning of this entire course, we created advertiser cards. How to use them now? 4. in userDetailView, when you rotate the device there is no way back (other than un-rotate) :) maybe we could disable rotation i certain screens?

Sharing my version of Brian's solution for changing the indicator bars after a tap: ``` if let index = controllers.firstIndex(of: currentController) { let tapLocation = gesture.location(in: view) let delta = tapLocation.x > view.frame.width / 2 ? 1 : -1 let nextIndex = max(0, min(controllers.count - 1, index + delta)) if index == nextIndex { return } let nextController = controllers[nextIndex] let direction: NavigationDirection = delta == 1 ? .forward : .reverse delegate?.pageViewController?(self, willTransitionTo: [nextController]) setViewControllers([nextController], direction: direction, animated: true) { (done) in if not(done) { return } self.delegate?.pageViewController?(self, didFinishAnimating: true, previousViewControllers: self.controllers, transitionCompleted: done) } } ``` The big difference is that my version calls two methods on the `UIPageViewControllerDelegate` which just so happens to be `self` (`delegate = self`) , thus avoiding the copy/paste.

For those who got white screen on user because you got empty String, you can use this for create your array of imageUrls: let imageUrls = [model.imageUrl1, model.imageUrl2, model.imageUrl3].compactMap { $0 }.filter { $0.isEmpty == false }

Hi Brian how could we go about adding the "Like" and "Dislike" icon to the top corners of the cards as a user is swiping?

I think you should warn your millennial students when their safe space is going to be violated with a trigger word like "mode". ;-)

That video was fire!

I just started to laugh because of the flashing of cards in the background.....Could be a great subliminal advertising technique to get users to buy whatever the owner wants to sell them!
