The Sample Mail App Extension project no longer builds under Xcode 13.1 due to conflicting swift and obj-c protocol method signatures

In the Earthquakes, example project & also mine I have noticed that view state is lost during device rotation. In portrait mode, the Table View / List is shown by default and in landscape mode, the pushed or detail view is shown instead. One how do you prevent the lost item selection in the landscape orientation when the detailed view is being loaded first without the primary List View to provide it with the incoming data? This is the current behaviour in the Earthquakes if anyone needs a code reference.

Is creating a custom ListStyle a public affair or private one between Apple and their developers?

Any documentation or examples on the use of @TableColumnBuilder is appreciated.

macOS - NSApplicationDelegateAdaptor iOS - UIApplicationDelegateAdaptor watchOS ?? WKApplicationDelegateAdaptor or WKExtensionsDelegateAdaptor Any help will be appreciated

WatchOS App only runs via Xcode 13.2.1 & Series 6 sim and when launched directly, crashes on launch due to a "FBSceneErrorDomain", "No scene client exist" error.

macOS app using a TabView, each tab's root view is using a @FetchRequest to populate a List view. while switching between tabs results in 1 ... (n * n) duplicate items on each tab switch. The behaviour is as if the internal update call in response to the SwiftUI view updating is not clearing the previous List view items but is appending to it. How do you clear or empty the List view on/or before every UI update call to the @FetchRequest property wrapper?

When all platforms are selected for download via Safari, it is a game of roulette where either a platform is not downloaded, Xcode is included in the download, or Xcode is not downloaded, but all four platforms are downloaded. This then creates a download mess with the manifest file because now you have a uncheck a few platforms and start all over again. How do you raise the Safari concurrent file download limit?

Without having to use @FetchRequest at the View level has any been able to successfully implement a CoreData Stack with observability in a model with the model being used at the View level. The view model sits between the View & Coredata Stack CoreData Stack ViewModel (ObservableObject) SwiftUI View

@Apple How do you set an iPad swiftUI app to Landscape only seeing that the Xcode supportedInterfaceOrientations flag is ignored by swiftUI. The following doesn't work via the UIApplicationDelegateAdapter when the 2 methods are implemented. func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {             .landscape         }       func supportedInterfaceOrientations(for window: UIWindow?) -> UIInterfaceOrientationMask {             .landscape         }

Does anyone know where to find the sample project?

Updating to macOS 13.3 - Previously Compatible WiFi network is now not compatible due to iCloud Relay. These changes were not mentioned in the release notes and if this is intended behaviour is iCloud Private Relay be deprecated? Then the magSafe light is now burning red on a full charged battery after the reboot.

Upgrade phone, then watch was paired to the new phone with developer mode enabled, but developer mode on watch is no longer visible on watchOS 10.4

Two days ago, the build number was 24B83, and now it's 24B2083, yet software updates don't see 24B2083 as the latest download.
