I understand Apple is enfin catching up with coding style and philosophy of our visionary teacher Brian which I am now somehow accustomed to after having finished Brian's several video tutorials. No wonder I feel very comfortable with SwiftUI. Merci beaucoup!
we'll need a tutorial on making a network request and displaying data and images, please! Thank you for this tutorial we're catching up very quickly on the new framework!
If you want to make a network request and display stuff, what I've been doing is using an loading all of the data in the SceneDelegate asynchronously with an @EnvironmentObject that I pass into the root view in the SceneDelegate. You can then do conditional checks and stuff in your views so that you can display something while the content loads. There's a good tutorial on EnvironmentObjects here: www.hackingwithswift.com/quick-start/swiftui/how-to-use-environmentobject-to-share-data-between-views Once you get the hang of it, SwiftUI is certainly WAY easier to do stuff like this in than UIKit.
If I didn’t go through your course, I would be totally lost. Now, looking at how you built this app, I can see that using your tools, swiftui is very simple. -Patrick
Nice work! I'm working on SwiftUI and was stuck with the image issue you mentioned at min 23:00! Thanks, keep doing this kind of videos, we appreciate!
I just followed this tutorial and my scrollview wouldn't scroll till i added ScrollView(.horizontal), like this. Just posting in case anyone encounters the same problem
ForEach syntax changed a little bit in newer versions of swift, its causing an error on tutorial code... New syntax: ForEach(posts, id: \.self) { post in Text(post) }
I found some codes are not working in my XCode. Here is my revision. 1. ForEach(Range, id: \.self) { } Or, insert let id = UUID() in struct Post: Identifiable 2. Text("blah blah").color(.primary) is not working. Instead, use Text("blah blah").foregroundColor(.primary)
resizable() gives you a similar effect to clipped. Well, it resizes it instead of clipping it. But either way, makes it smaller. UPDATE: Just got to the point in the video where you decide to use resizable.
Hey Brian! First of all , thanks for your afford doing all this amazing tutorials. I also studied the new SwiftUI tutorial, and maybe this modifier helps you to ignore the "Safe Areas" instead of using the padding. The modifier is ".edgesIgnoringSafeArea(.top)" in your case .leading. I couldn't try it yet. greets from Germany
Hey mate, commenting out just to let you know the `.padding(.leading, -20)` can be done by `.listRowInsets(EdgeInsets())` or just `insets(EdgeInsets())` which is a better approach
Hi Brian, for correct dynamic aspect ratio of the Post Image I set the frame of the image in PostView struct like that: .frame(minWidth: 0, maxWidth: .infinity, minHeight: 0, maxHeight: .infinity, alignment: .leading) and the padding of VStack like this: .padding(.init(top: 0, leading: -20, bottom: -8, trailing: -20))... This work perfect for me, is this the right way? THX
I just completed this, and had to make a couple changes to get it all to fit: The "post_puppy" image needed to have the addition of ".aspectRatio(contentMode: .fit)", and also had leading padding of zero and trailing padding of -20.
Super cool tutorial. Q: all the images are „somewhat hard coded“. How would this work if you had i.e. 3 users, they upload a picture and as you pull down the feed, it updates and shows the new posts. Surely one would also hook it up to firebase or so, but a tutorial on that in swiftUI would be super cool 🤙🤓📱🤩
Great tutorial! Is there a way to set the List as a horizontal style instead? Back in old days an UICollectionView would do the job, but how do we do that with SwiftUI?
@@LetsBuildThatApp Nice, can't wait. I can see that we will no longer need RxCocoa framework once SwiftUI + Combine dominates the developer community.....haha very exciting.
NavigationLink is not working for me, If i used top header. Could you please add NavigationLink in this video? Like to display detail screen. Thanks in advance!!
Hi Brian. If you were just starting to develop a new app, would you download the beta Xcode, wait for the final release, or develop with UIKit and refactor to SwiftUI further down the road? Also, I noticed you upgraded to the new OS X on your old machine but not the new one. How risky is installing the new OS at this point and who would you recommend could do that? Thanks, your tutorials are fantastic.
This is such a great video. With SwiftUI I know you can make cross platform apps, but could you use original Swift in addition to it for things like a normal for loop and still make the app cross platform? Or does it have to conform only to SwiftUI?
SwiftUI is amazingly powerful. Thanks Brian! But I'm wondering how you can specify the snappy horizontal collection view behavior like we did before by using SwiftUI? It looks to me like a separate layout file from the actual coding part of an app by far.
For the scrollview portion though, you lose all the cell recycling capabilities right? Or is SwiftUI smart enough to not render until it shows even in ScrollView()?
Great work so far with SwiftUI! The auto completion is sooo annoying !!! I’m struggling to get a Tabbar to work correctly (TabbedView) do you have any experience with it? I followed the WWDC video “SwiftUI essentials” and its not working for me 😬😬 they also use a View that is currently not available in the Beta “Form”? Greets from Stuttgart Germany! Love your content!
Hello, Thanks again for your video. Is "var body: some View " must to have when declaring new view? And How can we implement MVMM or MVC model when we use SwiftUI? Regards.
I got an error value of type '[String]' has no member 'identified' with ForEach (6:23). Just change to ForEach(posts, id: \.self) they changed it in Xcode 11 Beta 5 and above
Anyone know how to make the horizontal ScrollView maintain it's scrolled position. When you scroll down the ScrollView resets it's position. Any help would be awesome :)
In XCode 12.2 "NavigationButton" has been deprecated. Use "NavigationLink" instead, as follows : NavigationLink(destination: GroupDetailView) { GroupView() } Thanks for a great tutorial.
Could you make a tutorial on CollectionView kind of Grid which is inherit from UIViewRespresentable and When tap on that collectionviewcell need to navigate to some other swiftUI view.Thanks in advance.
Hey Brian I asked this question in a previous video but is there a difference in RAM usage between the live preview and simulator? Is it less with the live preview?
i notice navigationbutton has now changed to navigationlink which automatically adds an annoying arrow, this ruins the look of your sample app somewhat
This was something I struggled with.. how is it possible to have a collection view that displays users post, but above the collection view it displays a horizontal view with different user profiles to follow or something like that?
I’m on beta 4 and I‘m working on a similar layout as your „Trending“ view (horizontal scrollbar with clickable images that open a new view). NavigationButton is deprecated and replaced with NavigationLink. But my issue is that when I use NavigationLink for the individual images in a list element, the images are not clickable. But what happens is that the List item where the horizontal scrollbar is in, gets clickable. I think it‘s a bug because I‘m using the same code as in one of Apple‘s tutorials. Does the same happen to you? Is there a decent workaround so my app at least works for now?

Hey, we were planning to launch a app after ios13 launch. And some backend classes are ready. We are using firestore for login and our database. We have to start writing code in july after ui design, what would you recommend? Storyboard or swiftui. And if storyboard , how difficult it would be to use swiftui after that.

@@Aaron-dt3xz I have to pass .environmentObject Everytime I present a next screen if I don't do it my app crashes
Donat Hmm If you pass .environmentObject in the SceneDelegate then you shouldn’t have to do it for every view.
@@Aaron-dt3xz I have done it but still crashes. Maybe because of the beta
These complete App build-out's this early are fantastic!

TwoTwenty8 LLC your videos should use distinguishing thumbnails
Could you make a tutorial on using the TabbedView ?
Always the best! Thanks for this video.
In case the "identified by" is not working -
ForEach(posts, id: \.id) { post in
Text(post.propertyName)
}
I found that case. It changed "ForEach(posts, id: \.self) { Text($0) }" good luck :)
Apple has changed the syntax below is the correct syntax -->
ForEach(users , id: \.id ){
user in
UserRow(user: user)
}
Thanks Alot, It was really Helpful. I just did a small modification and moved Text("trending") before top vstack to have it while scrolling.
Nice work! I'm working on SwiftUI and was stuck with the image issue you mentioned at min 23:00! Thanks, keep doing this kind of videos, we appreciate!

Hi Brian. About padding make sense to use
Text("Some text").padding([.leading, .trailing], 12)
or
Text("Some text").padding(.horizontal, 12)
Man keep that work! You are the best at swift tutorials in the platform. Highly recommended 🙌🏻
Hi Brian, I believe you can you use .edgesIgnoringSafeArea() function on the VStack instead of -20 padding :)
Cleaner solution, thumbs up
Awesome no words ... NYC explanation ...
I just followed this tutorial and my scrollview wouldn't scroll till i added ScrollView(.horizontal), like this. Just posting in case anyone encounters the same problem
Thank you! How did you figure that out?
Even I did struggled on the same and then ended up discovering that
@@areola_ayatollah I just thought maybe because i was not specific with the kind of scroll direction i wanted so i implemented that
thanks for amazing tutorial.i can't see these replies
if you don't want scroll indicators set ScrollView like that: ScrollView(.horizontal, showsIndicators: false)
Great tutorial! SwiftUI is such a massive game changer for iOS dev! Thanks Brian! 😁

Here is my revision.
1.

Instead, use Text("blah blah").foregroundColor(.primary)

Quick question is this not Apple's Version of flutter
In order to be able to scroll the "ScrollView" you must ad a ".horizontal" so it looks like this
ScrollView(.horizontal){
}

Hey, we were planning to launch a app after ios13 launch. And some backend classes are ready. We are using firestore for login and our database. We have to start writing code in july after ui design, what would you recommend? Storyboard or swiftui. And if storyboard , how difficult it would be to use swiftui after that.
I personally haven’t used storyboards for 4 years. Swiftui is up and coming but I wouldn’t refactor entire codebases until maybe a year after release.
Lets Build That App so what should i do, start building app in old way and refactor code base next year when its out of its beta phase.?
Refactors easy and you have to do it anyways in a year.
Lets Build That App Thanks, i will do it in old way. It would be helpful if you upload a tutorial on this topic. “Change storyboard to swiftui”.😬
