yo, it's me again ;) I wonder..in the real world app.. what would be responsible for cleaning old photos (assuming 3 photos per user)? Some bots / processes on the server automatically? Or app/client itself?

hi Brian, at the moment we r just using dummy emails for login or registering.How will we verify if the email is real or not.

Hi Brian, Here's something I discovered .. using the higher-order function compactMap (compacts out nil items) for CardViewModel - func toCardViewModel() -> CardViewModel { ... let imageUrls: [String] = [imageUrl1, imageUrl2, imageUrl3].compactMap { $0 } return CardViewModel(imageNames: imageUrls, attributedString: attributedText) }

hey there, could you go a bit in deep with what you mean at 21:12, a fix for the flashing?

That video was fire!

some flashing occurs is a big bug because it's showing the backside of a photo for a little bit milliseconds please solve this. when I run the app last image showing for milliseconds in the first position and then original image is showing.

Hey Bryan, I am getting a crash on the line let imageUrl = imageNames[imageIndex] in the CardViewModel / Fatal Error: Index out of range. I also am not getting the barView to show when I have a single image only in my project. I was not getting an issue before this video and have compared my code to your project. I don't see anything different. I understand the error but am not sure how to trouble shoot it. fileprivate var imageIndex = 0 { didSet { let imageUrl = imageNames[imageIndex] //let image = UIImage(named: imageName) immageIndexObserver?(imageIndex, imageUrl) } } // Reactive Programming var immageIndexObserver: ((Int, String?) -> ())? func advanceToNextPhoto() { imageIndex = min(imageIndex + 1, imageNames.count - 1) } func goToPreviousImage() { imageIndex = max(0, imageIndex - 1) }

In my one of the project, I have used UIViews for horizontal list.. Then understood what it's like when you don't use recycler component! (Loads of performance issues) Which is why I need to rewrite entire feature. :( But any way, there won't be any performance overhead in our case since we are removing entire UIView from superview on swipe and we have a pagination in place. But loading 200 cards in a batch will still be expensive? What do you think? I would really appreciate if you kinda add another video which uses CollectionViewCell instead of UIView for cards..

Hey Bryan, Any advice on the issue I posted a few days ago? Do you need more info to assist?

nvm Bryan, Figured it out. Set a bunch of breakpoints and realized I was never getting a user object returned. Made the necessary adjustments and am all good.

why does firebase only show "imageUrl3 = "";"?

Fire!

Has anyone implemented the change to upload the photos upon pressing save (14:10)? I am trying to do it but I think it requires a closure as it doesn't otherwise wait for the entire uploadPhotos function to finish before continuing handleSave. I can't seem to figure out how to do it.

Hey Brian, For some reason when I go back to the Settings controller the data that I have saved is not there. After I upload the images I get this for the user USER>>>> Optional(TinderFireStoreEB.User(name: Optional("Qu"), age: Optional(25), profession: Optional("Dev"), imageUrl1: Optional("https://firebasestorage.googleapis.com/v0/b/matchfirestoreeb.appspot.com/o/images%2F1E17BD03-4A69-4415-9D8A-7CBA7FD8BA1A?alt=media&token=e94974f3-a6bd-47aa-ada9-7e682c23d982"), imageUrl2: Optional("https://firebasestorage.googleapis.com/v0/b/matchfirestoreeb.appspot.com/o/images%2F2E8C6F1E-31AC-45AD-B635-F4032C6736FE?alt=media&token=0fcda562-5659-423b-9e6c-1b9fcff1a62a"), imageUrl3: Optional("https://firebasestorage.googleapis.com/v0/b/matchfirestoreeb.appspot.com/o/images%2F615D50A5-80D2-49D6-BFE3-9586D52DC36C?alt=media&token=d8bf5e84-21b0-4b03-8943-d03141100789"), uid: Optional("OvEk2miWTpY3QwVmg8mspPAEMfH2"))) . It is after I click save button. If I click cancel and go back to @objc fileprivate func handleCancel() { dismiss(animated: true) } My data is not there and I get imageUrl2: nil, imageUrl3: nil . Couldn't figure out why it is happening..... Any help would be appreciated.

Same with textfield, we can also set button.tag for more clean code.

I think currently the way we are storing images to Storage, its able to be duplicated. We are saving it under a uuid, so if someone selects the same image again and save, they are technically uploading the same image but just under a different name. Is there any way to avoid that?
