Using a navigation controller in a tab bar controller the large title glitches when switching tabs.SceneDelegate.swiftif let windowScene = scene as? UIWindowScene { let window = UIWindow(windowScene: windowScene) let tabBarController = UITabBarController() tabBarController.viewControllers = [UINavigationController(rootViewController: ViewController()), UIViewController()] window.rootViewController = tabBarController self.window = window window.makeKeyAndVisible() }ViewController.swiftself.view.backgroundColor = .systemBackground self.title = "Main" self.navigationController?.navigationBar.prefersLargeTitles = true self.navigationItem.largeTitleDisplayMode = .always scrollView = UIScrollView(frame: self.view.bounds) self.view.addSubview(scrollView) let contentView = UIView(frame: CGRect(x: 0, y: 0, width: self.view.frame.size.width, height: 1400)) contentView.backgroundColor = .gray self.scrollView.addSubview(contentView) scrollView.contentSize.height = 1700Steps to reproduce:Scroll down until the large title collapses into the small titleSwitch to the second tabSwitch back to the first tabResult: The scroll view is still scrolled down but the large title now overlaps the content. When scrolling a little bit, it snaps back to the small title.This does not happen when it’s a table or collection view instead of the scroll view.This started happening in iOS 13. Did I miss some change in the behavior or is this a bug? Does someone know a workaround?

FB7732283I am currently having an issue with table and collections views and their insets in conjunction with large title navigation bars. When you scroll up until the title transitions to the small variant, there is no margin between the content and the navigation bar in the case of an inset grouped table view or a collection view. To mitigate that I tried to use contentInsets.top on that table view. While there is now a top margin, when I scroll there's this weird behavior where the scroll view snaps halfway through and when scrolling until the title transitions to the small variant again, there's no margin any more. Am I missing something very obvious or how can I achieve this in the correct way?A video of that problem can be seen in this tweet of mine https://twitter.com/ps3zocker/status/1270641775192018944

I have a layout similar to Music or Podcasts, where I have a sidebar and a grid content area. When clicking on one of the items in the grid I want to open a full screen detail view just like Music does. My question is: How can I display a back button in the toolbar? I only figured out how to add buttons to the trailing side of the toolbar. Is this even possible in pure SwiftUI?  .toolbar {             Button(action: showSearch) {                 Label("Add Game", systemImage: "plus")             }         }

How can I use the same translucent selection style in the sidebar that apps like Finder, Music, and Podcasts use? By default Mac Catalyst apps seem to use the tint color for the selection, which looks out of place with the system apps. I use UICollectionLayoutListConfiguration by the way.

Is it possible to use the new search button/bar style in macOS Big Sur with Mac Catalyst? The new NSSearchToolbarItem is marked as unavailable in Catalyst. If not, what is the recommended way to add a search field to the window toolbar?

How would I use the new subtitle property that has been introduced on NSWindow in macOS 11 with Mac Catalyst?

When I'm using this code to display a toolbar item in Mac Catalyst to show the new UIMenu context menu behavior, the toolbar item is disabled because there's no primary action. Is this a bug or does this need special care on Mac Catalyst to work?     func toolbar(_ toolbar: NSToolbar, itemForItemIdentifier itemIdentifier: NSToolbarItem.Identifier, willBeInsertedIntoToolbar flag: Bool) -> NSToolbarItem? {         if (itemIdentifier == addLinkButtonIdentifier) {             let barButtonItem = UIBarButtonItem(title: "Test", image: nil, primaryAction: nil, menu: addLinkContextMenu)             barButtonItem.accessibilityLabel = "Add Link"                          let button = NSToolbarItem(itemIdentifier: itemIdentifier, barButtonItem: barButtonItem)                          return button         }                  return nil     } }

Am I right in assuming that it's still not possible to have a native Preferences window in Mac Catalyst using the .preferences toolbar in macOS 11 except when using a Settings bundle?

What's the recommended way to add a search bar in Mac Catalyst? The new NSSearchToolbarItem that was introduced in macOS 11 is not available in Catalyst. What's the alternative? FB7828248

Hi! I've set up a sample project to test out the usage of Core Data and Diffable Data Sources and I was wondering what the correct setup is. When fetching 15.000 items with the NSFetchedResultsController and the old data source method, the app takes up about 5.8 MB. When doing the same with a manual fetch, it takes about 13.9 MB. And when using NSFetchedResultsController in conjunction with diffable data source, it uses around 13.3 MB. Am I right in assuming that using diffable data source with NSFetchedResultsController is removing the memory optimization (not loading all objects at once)? And therefore the biggest difference between a manual fetch and a NSFetchedResultsController fetch is the automatic updating? What's the recommended way to use Core Data today? The way I see it, using NSFetchedResultsController with the classic data source model is the most efficient? And using manual fetching or using NSFetchedResultsController with diffable data source yields around same memory usage?

Is there a way to use SwiftData without automatic iCloud sync? I’d like to do that manually using my own CloudKit solution or CKSyncEngine. SwiftData automatically picks up any CloudKit containers though and I have not seen an option to disable this behavior. Setting cloudKitContainerIdentifier to nil does still pick the first available CloudKit container. Just in case this is a bug: FB12276416 Sample: let configuration = ModelConfiguration(cloudKitContainerIdentifier: nil) let modelContainer = try! ModelContainer(for: [GamesCollection.self], configuration) print(modelContainer.configurations) // [SwiftData.ModelConfiguration(url: …, name: …, sharedAppContainerIdentifier: …, cloudKitContainerIdentifier: Optional("iCloud.CloudKit.com.+++")

[Detailed feedback FB15232205] Since I restored my new iPhone 16 Pro from a previous iPhone 15 Pro backup, I can't use stickers any more. The stickers gallery is filled with clear stickers that I can't interact with. Deleting does nothing. I also can't add new stickers. They appear for a second and then disappear again. iCloud sync is also not working. Other devices are fine. When restoring the phone without backup, everything works fine. Is it possible this is caused by the iOS 18.0 version that's shipping with the new iPhones? I was only offered another iOS 18.0 update in Settings later on. Updating to 18.1 beta 5 today did not fix it either. From what I gather from the logs, there's a database corruption happening. I've seen various posts across the internet who have this issue specifically after setting up their new iPhone. fehler 22:08:24.677501+0200 stickersd error: (11) Fatal error.
