All the things that I was looking for to create a wee map in my mind as to what is possible for apps come this September. Really enjoy your enthusiasm. The biggest thing for me for this update is the attention being paid to the Navigation of the iPad and how someone with a limited amount of coding ability can, through a bit of study, start manifesting ideas that can go across the different platforms, where the iPad or Mac is a central point for data input and key organisation and the iPhone is the smaller representation of ones carefully designed ideas, plans and information. Nice one !!!

You add a VStack { and then complete the end of the stack with a } brace and it reformats for you. Saves another step. Safe travels home!

Great overview, Paul! Thanks! I'm loving all the updates Apple has made to SwiftUI. There's not a single one I can think of that isn't well deserved or greatly appreciated. It's probably going to take me a month to go through and absorb all the session videos. I spent weeks last fall getting a NavigationView to behave just the way I needed it to, but it's clunky at best, and now I can easily replace it all with a simple NavigationStack. It's exactly what I need. Top of my wishlist would be to give Gestures some much needed love, like being able to pan and zoom a view at the same time without having to delve into UIKit and using gesture recognizers. Or having swipe gestures like UIKit has.

For me, they've pretty much addressed all of the pain points I've had as far as I can tell. I really wanted the Window scene and it's there, plus they added the MenuBarExtra scene, which is just a bonus for me. I hated the lack of customizability of forms on macOS and it's now resolved for me. I hated the lack for programmatic navigation and now that's resolved. The fact that they added in Swift Charts just blows my mind. Oh and the grid layouts and any layouts solves so many issues. I honestly can't see any reason why anyone would use UIKit / AppKit when building a new application now. I was extremely hyped for WWDC this year and Apple did not disappoint.

SwiftCharts doesn't give you much more fidelity in creating custom UI, it doesn't bridge the gap between custom controls rendered on Quartz/CoreGraphics.

The biggest problem for me is still the distance between what a designer creates in Abstract or Sketch, and the code needed to create a UI component that isn't easily created using SwiftUIs limited controls, whereas CoreGraphics gives us the fidelity to do as such.

Hi, I’ve found your tutorials and videos very useful. I’m a software engineer but I’ve only recently picked up Swift and SwiftUI for interest. One thing that I find isn’t properly explained is optimal server side solutions for applications. For example, if I were to create a social media application, is there a recommended service/infrastructure to store things like user data and anything sensitive? I’ve seen some people refer to Firebase and others using standard SQL variants but there isn’t much beyond that. Any advice or resources?

Good video. The problem with TextField (at least on iOS 15) is that it is buggy with custom bindings. What you see in the text field won't be in sync with the stored value when you modify it in the set block. For example, if you remove all the numbers in the string before assigning it to the state value in the custom bindings set block, what you see in the text field itself will only be updated to remove the numbers when entering a non number afterwards. TextEditor don't have this issue, it will immediately update the contents when modifying the value in set. I have also checked that set is indeed called for every number entered, it's the text field that just won't show the updated value, as well as the value it supplies as a parameter to the set block will be the unmodified one(the same shown in the text field). Another issue with TextField is that it will call the custom binding set block twice for every character you enter, TextEditor only calls it once. Hopefully these issues are fixed in iOS 16.

Because by default, there is no modifier that changes Lists background color, and before iOS 16 I use to use a « UITableView.appearance() » in the init() of the view to change that, but it seems like that this doesn’t work anymore on iOS 16 :/

Can you use this new NavigationStack for iOS 16, but still support for iOS 14.0 (SwiftUI 2)? I struggling trying to adapt my project in order to support all versions from 14.0. The reason I'm trying its because I have encountered some bugs using NavigationView in iOS 16.4 and 16.5. One of those bugs is that when keyboard is present If I press on some button that open some navigationLink programmatically, then the navigation won't open or will close it self. The funny thing is that when I focus any field... the navigation will fire. Can you help me Paul, please?

Maybe the issue has already been reported? When I run the first example of NavigationStack with path: in the simulator, I get the following runtime error: A NavigationLink is presenting a value of type “Int” but there is no matching navigation destination visible from the location of the link.

A question for you are other commenters: you said in your how to become an iOS developer video not to use beta software, but SwiftUI seems to have changed quite a bit, particularly with navigation. Should I start with SwiftUI 4.0 and change if something changes during the betas, or start with 3.0 and learn 4.0 in the fall. I am only new to Swift and SwiftUI, not development in general. Thanks!

The main lesson you should learn is that change is a constant and learning has no end. If you're getting into programming, you should be prepared to be a student for life. I've been doing this professionally for over 17 years and I'm still learning every day. My view is it's fine if you begin with the beta software as long as you're aware that the APIs could and possibly will change between now and ~September, when the final versions will be released.
