Hey Brian, how does the Pagination of Tinder is working. They have for sure also pagination but how the handle the new added Users and the Users which have already been voted on. I can not really wrap my Head around this. Are they Filtering with a List (for each User) which Users are already been voted on or is there a more advanced technique. I really like to hear your approach on that :)

Hi Brian, I have read that it is a good practice to keep UI related elements on the main thread, and therefore would think that it is better to place the huds inside a dispatchQueue.main.async(). I noticed that you did not practice this widely in this tutorial, so would like to hear your opinion on this. Is it because it's not necessary? Or omitted for simplicity of the tutorial.

Hey Brian! Loving the videos so far! I was wondering how we can paginate without a refresh button, so that as the user is swiping through the cards more cards will get loaded as they near the end ?

Shouldn't we reuse Cards from a pool?

Although I added: "cardsDeckView.sendSubviewToBack(cardview)" I still experience flickering. Am I the only one experience that problem? Any solutions/suggestions?

That video was fire! Will definitely visit the pagination page on Firebase documentation.

I really could not understand the usage for "cardsDeckView.sendSubviewToBack(cardview)", please a brief bit more. + the sessions are becoming more of tool oriented intents to lose interest

Hi Brian, I'm running into a little problem. I am able to fetch all users from Firestore, but when I call the .order/.limit methods it only works for the first time when loading the app. When hitting refresh it fetches only 1 specific user is fetched, I deleted this user and now nothing is being fetched when hitting refresh. I appreciate having ur thoughts on what might be the problem provided that I copied and paste it your query code and still got the same result. Thanks.

Does anyone have any code snippet that will re paginate after the limit is reached? so if your limit is five cards, it will re-run the query automatically after you swipe the last card? I cant seem to find any videos or info on stackoverflow regarding how to do this in swift for firestore....

How do you paginate so that the next time you use the app it will show you people based on where you left off and not show you the people you already swiped?
