Great work Nick. I think it is great learning incidental things, like making custom ViewModifiers, as it shows us real examples of when it is useful in our own apps.

For somebody who is following your playlists you are not going too difficult, this whole context of informations gives me much better understanding! Love your videos even more than Paul Hudsons (biggest swift achievement)

[andresraigoza]

Awesome! I love how you take your time to organize and write the code as good as possible, please keep up the great work you deserve the best.

[AISecretss]

Your explanation of the lesson is perfect👍👍

Amazing bootcamp so far!!! Can't wait to use all these skills in my new projects 🔥

[omerfarukozturk]

You create incredible content. Thanks to you, I am learning SwiftUI and developing projects. I'd love to meet you.

Thanks again for this excellent content. Your videos are a great source of information for developers and enthusiasts like myself.
Are you a full-time developer? I wonder how you find the time to create these videos.

[kauekaj]

Awesome work Nick! Thanks for making such amazing videos for us.

[awu]

Love this video! Looking forward to the chat app!

At around minute 21:00 you modify the product id and the view doesn't update because the view is based on the id not product id. I don't understand that. Btw amazing series

[EmanNollase]

This is awesome!!! if you continue with a chat app sample that would be great!! thanks

Yo, nice video, helped up out a bunch!! Only question I have is how can I add pagination in with realtime updates? Been messing with it for a few hours with no joy at all. Any tips or pointers on this would be GREATLY appreciated. Keep up the good workman, hope it pays off for you.

❤ what’s coming after this firebase course?

[Designguidetv]

thank you, this was amazing, also my brain is exploding but it will pass

[caphis]

Awesome content Nick. Just curious - do you plan to cover Push Notifications using FCM later in the playlist?

[Alicode.]

Great work. I confused while add listener to other case, I trying to add listener to get all products but I don't succeed.

Do you have any videos outlining how to attach a listener/publisher to a record Detail View? This works well for record List Views where there is an array of records that get updated, but I am struggling to get the same setup to apply to my record Detail Views.

For example, a User clicks into one of the Favorite Record products and updates a status on it such as "Ordered". I would want the user to be able to see that the status got changed without having to leave the record Detail View and go back to the record List View (In my project, I have a PopUp on the record Detail View where the user can update the record status through an "updateStatus" function that calls out to Firebase and updates the specific record. However, I cant get the record Detail View to update in real time).

For my scenario, would you recommend just updating the variables locally on the record Detail View as when the User leaves the record Detail View and goes back to the record List View the values will be refreshed anyways? Wondering what the best practice is here.

Hello Nick,
thank you so much for this great bootcamp, I’ve learned a lot! But there is one thing I didn’t figured out yet.
How can I combine the listeners with the pagination function?
For example I have a FeedView like Instagram or Twitter where I want to download only 20 posts at once (pagination) but also want to listen to the changes which a post owner can apply to his post.
What’s the best way to manage these case?

[josejaimefelixgarciagarcia]

Is it possible to edit the data in google sheets? So that non-developers would be able to update the collection?

[ЙорданМансарлийски]

Is it possible to create a pagination with firestore listeners?
