Hi, How to customize tables in SwiftUI its color background for example, the background modifier doesn't work ? how to change separator lines ? rows background colors ? give header row different colors to its text and background color ? Kind Regards

I have a CALayer and I'd like to animate a property on it. But, the property that triggers the animation change is different to the one that is being changed. A basic example of what I'm trying to do is below. I'm trying to create an animation on count by changing triggerProperty. This example is simplified (in my project, the triggerProperty is not an Int, but a more complex non-animatable type. So, I'm trying to animate it by creating animations for some of it's properties that can be matched to CABasicAnimation - and rendering a version of that class based on the interpolated values). @objc class AnimatableLayer: CALayer { @NSManaged var triggerProperty: Int @NSManaged var count: Int override init() { super.init() triggerProperty = 1 setNeedsDisplay() } override init(layer: Any) { super.init(layer: layer) } required init?(coder: NSCoder) { fatalError("init(coder:) has not been implemented") } override class func needsDisplay(forKey key: String) -> Bool { return key == String(keypath: \AnimatableLayer.triggerProperty) || super.needsDisplay(forKey: key) } override func action(forKey event: String) -> (any CAAction)? { if event == String(keypath: \AnimatableLayer.triggerProperty) { if let presentation = self.presentation() { let keyPath = String(keypath: \AnimatableLayer.count) let animation = CABasicAnimation(keyPath: keyPath) animation.duration = 2.0 animation.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.linear) animation.fromValue = presentation.count animation.toValue = 10 return animation } } return super.action(forKey: event) } override func draw(in ctx: CGContext) { print("draw") NSGraphicsContext.saveGraphicsState() let nsctx = NSGraphicsContext(cgContext: ctx, flipped: true) // create NSGraphicsContext NSGraphicsContext.current = nsctx // set current context let renderText = NSAttributedString(string: "\(self.presentation()?.count ?? self.count)", attributes: [.font: NSFont.systemFont(ofSize: 30)]) renderText.draw(in: bounds) NSGraphicsContext.restoreGraphicsState() } func animate() { print("animate") self.triggerProperty = 10 } } With this code, the animation isn't triggered. It seems to get triggered only if the animation's keypath matches the one on the event (in the action func). Is it possible to do something like this?

I have a SwiftUI based program that has compiled and run consistently on previous macos versions. After upgrading to 15.2 beta 4 to address a known issue with TabView in 15.1.1, my app is now entering a severe hang and crashing with: "The window has been marked as needing another Update Contraints in Window pass, but it has already had more Update Constraints in Window passes than there are views in the window. .<SwiftUI.AppKitWindow: 0x11d82a800> 0x87 (2071) {{44,0},{1468,883}} en" Is there a known bug that could be causing this crash or known change in the underlying layout model?

Hi, would anyone be so kind and try to guide me, which technologies, Kits, APIs, approaches etc. are useful for creating a horizontal window with map (preferrably MapKit) on visionOS using SwiftUI? I was hoping to achieve scenario: User can walk around and interact with horizontal map window and also interact with (3D) pins on the map. Similar thing was done by SAP in their "SAP Analytics Cloud" app (second image from top). Since I am complete beginner in this area, I was looking for a clean, simple solution. I need to know, if AR/RealityKit is necessary or is this achievable only using native SwiftUI? I tried using just Map() with .rotation3DEffect() which actually makes the map horizontal, but gestures on the map are out of sync and I really dont know, if this approach is valid or complete rubbish. Any feedback appreciated.

I can't shake the "I don't think I did this correctly" feeling about a change I'm making for Image Playground support. When you create an image via an Image Playground sheet it returns a URL pointing to where the image is temporarily stored. Just like the Image Playground app I want the user to be able to decide to edit that image more. The Image Playground sheet lets you pass in a source URL for an image to start with, which is perfect because I could pass in the URL of that temp image. But the URL is NOT optional. So what do I populate it with when the user is starting from scratch? A friendly AI told me to use URL(string: "")! but that crashes when it gets forced unwrapped. URL(string: "about:blank")! seems to work in that it is ignored (and doesn't crash) when I have the user create the initial image (that shouldn't have a source image). This feels super clunky to me. Am I overlooking something?

If I have a Catalyst app with a WKWebView and I select text, I can drag forward to extend the selection, but I can't reduce the length of the selected range by dragging backwards. I've reproduced this in a trivial sample app. Is there some property I need to set somewhere? I've filed this as FB15645411.

Our tvOS app makes use of top shelf Carousel style slides to promote our content. We would like to detect when tvOS transitions between individual top shelf slides, regardless of whether the slide transition is made by a user (via the Siri remote), or by the system idle auto-transition. Has anyone achieved this, maybe there are undocumented system hooks or events we can listen to?

I'm trying to configure the share sheet. My project uses techniques from the Apple Sample project called CoreDataCloudKitShare which is found here: https://developer.apple.com/documentation/coredata/sharing_core_data_objects_between_icloud_users# In this sample code there's a "PersistenceController" which is an NSPersistentCloudKitContainer. In the "PersistenceController+SharingUtilities" file there are some extensions, and one of them is this: func configure(share: CKShare, with photo: Photo? = nil) { share[CKShare.SystemFieldKey.title] = "A cool photo" } This text "A cool photo" seems to be the only bespoke configuration of the share sheet within this project. I want to have more options to control the share sheet, does anyone know how this might be achieved? Thank you!

Hi, This issue started with iOS 18, in iOS 17 it worked correctly. I think there was a change in SectionedFetchRequest so maybe I missed it but it did work in iOS 17. I have a List that uses SectionedFetchRequest to show entries from CoreData. The setup is like this: struct ManageBooksView: View { @SectionedFetchRequest<Int16, MyBooks>( sectionIdentifier: \.groupType, sortDescriptors: [SortDescriptor(\.groupType), SortDescriptor(\.name)] ) private var books: SectionedFetchResults<Int16, MyBooks> var body: some View { NavigationStack { List { ForEach(books) { section in Section(header: Text(section.id)) { ForEach(section) { book in NavigationLink { EditView(book: book) } label: { Text(book.name) } } } } } .listStyle(.insetGrouped) } } } struct EditView: View { private var book: MyBooks init(book: MyBooks) { print("Init hit") self.book = book } } Test 1: So now when I change name of the Book entity inside the EditView and do save on the view context and go back, the custom EditView is correctly hit again. Test 2: If I do the same changes on a different attribute of the Book entity the custom init of EditView is not hit and it is stuck with the initial result from SectionedFetchResults. I also noticed that if I remove SortDescriptor(\.name) from the sortDescriptors and do Test 1, it not longer works even for name, so it looks like the only "observed" change is on the attributes inside sortDescriptors. Any suggestions will be helpful, thank you.

In my iOS App I present a QLPreviewController where I want to display a locally stored Video from the iPhone's document directory. let previewController = QLPreviewController() previewController.dataSource = self self.present(previewController, animated: true, completion: nil) func previewController(_ controller: QLPreviewController, previewItemAt index: Int) -> QLPreviewItem { let url = urlForPreview return url! as QLPreviewItem } This seems to work fine for all but one of my testflight users. He is using an iPhone 12 with iOS18.0.1. The screen becomes unresponsive. He cannot pause the video, share it or close the QLPreviewController. In his logfile I see the following error... [AVAssetTrack loadValuesAsynchronouslyForKeys:completionHandler:] invoked with unrecognized keys ( "currentVideoTrack.preferredTransform") Any ideas?.

The Problem When transitioning between view controllers that each have their own MTKView but share a Metal renderer backend, we run into delegate ownership conflicts. Only one MTKView can successfully render at a time, since setting the delegate on one view requires removing it from the other, leading to paused views during transitions. For my app, I need to display the same visuals across multiple views and have them all render correctly. Current Implementation Approach I've created a container object that manages the MTKView and its relationship with the shared renderer: class RenderContainer { let metalView: MTKView private let renderer: MetalRenderer func startRendering() { metalView.delegate = renderer metalView.isPaused = false } func stopRendering() { metalView.isPaused = true metalView.delegate = nil } } View controllers manage the rendering lifecycle in their view appearance methods: override func viewWillAppear(_ animated: Bool) { super.viewWillAppear(animated) renderContainer.startRendering() } override func viewWillDisappear(_ animated: Bool) { super.viewWillDisappear(animated) renderContainer.stopRendering() } Observations & Issues During view controller transitions, one MTKView must stop rendering before the other can start. Also there is no guarantee that the old view will stop rendering before the new one starts, with the current API design. This creates a visual "pop" during animated transitions Setting isPaused = true helps prevent unnecessary render calls but doesn't solve the core delegate ownership problem The shared renderer maintains its state but can only output to one view at a time Questions What's the recommended approach for handling MTKView delegate ownership during animated transitions? Are there ways to maintain visual continuity without complex view hierarchies? Should I consider alternative architectures for sharing the Metal content between views? Any insights for this scenario would be appreciated.

Problem I am developing a WebDriver agent for automation and using dictionaryRepresentation to retrieve the coordinates of the iOS app hierarchy. However, I am encountering an issue with the accuracy of the x and y coordinates. Approach Tried I tested the setup on: iPhone 12 Pro Max (iOS 16.2): Accuracy issues with the coordinates were observed. iPhone SE (3rd Generation) (iOS 16.2): Coordinates were accurate for tap actions, with no issues identified. Observation It appears that devices with fingerprint biometric authentication provide accurate coordinates. Can anyone help here to understand is there anything wrong in the code. Are do we have to adjust frame of the element for different devices?

I want to support Genmoji input in my SwiftUI TextField or TextEditor, but looking around, it seems there's no SwiftUI only way to do it? If none, it's kind of disappointing that they're saying SwiftUI is the path forward, but not updating it with support for new technologies. Going back, does this mean we can only support Genmoji through UITextField and UIViewRepresentable? or there more direct options? Btw, I'm also using SwiftData for storage.

Developing on Monterey 12.7.5 I'm having trouble with updating subitems on NSToolbarItemGroup when selecting the item directly from the NSToolbar items array. I select the group item off the items array on the toolbar, and then call setSubitems: on the item, with a new array of NSToolbarItems. The group item disappears from the toolbar. It seems to leave a blank invisible item in the toolbar taking up space. I can't manually reinsert the item into the toolbar until I drag out the blank item, then drag back in the real item. Once dragged back in from the palette it displays correctly. The workaround I've come up with is to remove the item with NSToolbar removeItemAtIndex: and reinsert it with NSToollbar insertItemWithItemIdentifier:atIndex:. This works to update the subitems. Every other toolbar item property that I've tried has been able to update the item directly in the toolbar. It's only the group item's subitems that don't want to update correctly. Is there a correct way to do this that I'm missing? Calling [toolbar validateVisibleItems] didn't seem to help.
