Again one of the best course videos. Love how you pack the content of your videos into really practical units. Keep doing it. I've been through this infinite scrolling on Android + FB and would love to have some tutorials like these. It took me forever to figure it all by myself. Thank you . .

Amazing bootcamp Nick, thank you so much. Just a quick fix on this video. At 48:45 you missed the ".limit(to: count)" in the new condensed return statement. Otherwise, we are not really paginating and all the products are loaded at once.

You are not going too deep, KZfaq gives use the ability to coffee you up when needed, the expresso buttons 1.25, 1.5, 1.75, 2.0 😂Seriously these topics have many parts and pieces, I for one, love the depth.

Hi! Is it possible to use Firebase and remote push notifications without subscribing to a change? Like if I wanted to send out daily notifications with changing content (hence can't do local notifications) - could I just set up daily notifications that get data from the database?

Shouldn't there be a .limit in the final getAllProducts query?

Very nice. How would you achieve pagination with listeners like in a social network app? Will you have a listener for every page of, let's say, 20 documents? and how will you keep track of every listener and real time updates? or you just fetch pages statically and then add 1 single sitter for the whole list? What is the best practice?

Hey nick, I had commented on the codable video from the playlist. I’m getting errors with the custom encoder and decoder😢

@SwiftfulThinking Жыл бұрын

I would check your code, it’s really easy to use the wrong “encoding” vs “decoding” keywords since the functions are so similar

@@SwiftfulThinking I quadruple checked. it still says the same thing. Is there an email address I can send a screenshot to of the code?

Hey, Nick. Did you mean the following code (25:36) where we don't have to import FirebaseFirestore in every view? Please correct me if I've got it wrong. Thanks mate. import FirebaseFirestore struct LastDocumentSnapshot { var lastDocument: DocumentSnapshot? init(_ lastDocument: DocumentSnapshot) { self.lastDocument = lastDocument } } private var lastDocument: LastDocumentSnapshot = .init(nil)

I'm sure you already figured it out , but Yes ...how you wrote it is perfect....this way you can use it if want to use pagination in a view with list of users, products, or chat conversations , etc...
