I use to have my Sections (with header) within a List View that was within a NavigationView. Since NavigationView is now deprecated, I've transitioned to using NavigationStack. No other changes to code, but now my section headers don't have a triangle to show/hide the section content...i.e. the section is now longer collapsible. Your code above doesn't show what your ForEach statements are wrapped in. Are they within a List?

I've recently started an app where the content view uses this type of hierarchical list view (with children). I'm able to successfully display the hierarchical list in the content view, and when I tap an item in the hierarchy, I'm successfully able to navigate to a detail view for that tapped item. I'm also able to edit one of the tapped item properties in the detail view using a TextEditor view. However, when I click save in the detail view, the changed property will only be saved if it was the parent list item row that I tapped in the content view. If it was a child list item in the content view, the save does not work. I think I may have a problem in my save code logic and I'm trying to investigate.
I talked with Apple about this during a lab session at WWDC21. They had me create a feedback ticket.

Apple has some excellent SwiftUI and UIKit tutorials on the developer website. The tutorials allow you to work through the specific app creation projects that teach you the various technologies for SwiftUI and UIKit.

I'm having a similar problem but with an independent watch app using Swift UI. The live preview in Xcode shows a back button on the detail screen and it allows me to return to the parent (content view) screen. However, when I run the same app on the watch simulator and on an actual Apple Watch Series 6, the back button doesn't appear and I can't navigate back to the parent view.

Thank you very much! If I’m already logged into my GitHub account through Xcode using a password, do I have to log out and delete that account entry in Xcode and then create a new GitHub account and login with the token or can I just log out of the current GitHub account in Xcode preferences and then log back in with the new access token?

So how can I create that authentication token and then how do I set up my login in Xcode to GitHub to use that token instead of a password which GitHub is deprecating?
I think after talking to Apple engineers in a 1-on-1 lab, and seeing the response from in this other forum question - https://developer.apple.com/forums/thread/650776?answerId=615249022#615249022, I feel my questions have been answered.

Well, I tried creating a new test project using Xcode 12 Beta and a Watch Only template for watchOS, and, except for the HostingController entry point being replaced by the App.swift entry point and the ExtensionDelegate.swift file being removed, it appears the new project is still a WatchKit app project. The project still has multiple targets including WatchKit App and WatchKit Extension targets. Therefore, I'm still not sure what additional benefit I'd gain starting with a Xcode 12 Beta 100% SwiftUI project template.
Any insights would be welcome.

The project still has multiple targets including WatchKit App and WatchKit Extension targets. Therefore, it appears dealing with updating watch complications uses most/all of the same APIs that are used for the non-100% SwiftUI project template project from Xcode 11.
Ok. Since this is a watch only app and I don’t need to sync data with other devices, it sounds like using CloudKit is not necessary and I can use Core Data for local on-watch data persistence.
What is the latest and greatest information I can reference for using Core Data for my situation (Xcode 12 beta, watch only watchOS 7 app, SwiftUI)? Is there a WWDC20 video session that covers my situation? Example code?
I also highly recommend the following resources:
App Development with Swift - https://books.apple.com/us/book/app-development-with-swift/id1465002990
Apple’s SwiftUi Tutorial - https://developer.apple.com/tutorials/swiftui/
Udemy iOS App Development, Swift, and SwiftUI courses. I like the courses by Mark Price of Devslopes, Nick Walter, and Dr. Angela Yu of the London App Brewery.

From what I understood from the session video, a window is a type of scene.

I do understand that jacket and pins have been provided to SSC winners, as of now. However, I’m hoping Apple will make them available to broader WWDC20 community at some point. Do you know for sure Apple will not do this?
Had a good 1-on-1 lab session with DTS this morning. They gave me a couple of different options to fix this. It’s gonna take some work so I have to decide which approach to use. One of the approaches is to use some of the new Xcode 12 Beta APIs for iOS 14 to replace my current approach to my detail view controller and instead use an advanced collection view that might make things much simpler and let the collection view API handle all the spacing.
