Hello, we have HLS Stream app on Apple TV. Our streams are DRM protected. We have problem with streams when source device is turned off. For example, user start to watch our HLS DRM Protected content. After some time, user turns off device (it can be Monitor or TV via connected HDMI). Our app does not understand HDMI Source device turned off. Is there any way to understand HDMI connected device is turned off on Swift?

I'm in the process of migrating to the Observation framework but it seems like it is not compatible with didSet. I cannot find information about if this is just not supported or a new approach needs to be implemented? import Observation @Observable class MySettings { var windowSize: CGSize = .zero var isInFullscreen = false var scalingMode: ScalingMode = .scaled { didSet { ... } } ... } This code triggers this error: Instance member 'scalingMode' cannot be used on type 'MySettings'; did you mean to use a value of this type instead? Anyone knows what needs to be done? Thanks!

Is there any way to detect if an entity is being looked at in a RealityView. I know it is possible to add a "HoverEffectComponent()" which will highlight the entity a little when you gaze on it, but there doesn't seem to be any way to call a function from this. There is also no GazeGesture or anything similar.

The speaker mentions there is "less risk of creating a retain cycle in when capturing self in a closure within a value type", such as a SwiftUI view struct. Can you elaborate on when this could actually occur? Thanks!

Hi! I've detected that in iOS18 launch screen colors differs from the defined ones, that is, if I create a launch screen with a color like #ff0000 (red) and the initial view controller is a view controller with the same color as background, I can see the transition between launch screen and the initial view controller because the launch screen color is different from the other one (dark in this case). I've tested it with several colors: left side is the launch screen and right side is the initial view controller. Both views created with IB using the same colors (it also happens with background images using colors) Is this an intentionall behavior? If so, theres a way to disable it? I need the transition between the launch screen and my initial view controller to be non perceptible... Thanks!

In this UIKit app, I have to display numbers (from 1 to 100), in a label., on several lines, with 8 numbers on each line. Order is computed by the app for a specific purpose. The numbers are separated by space. Label font is Helvetica Neue 15.0. I want to get them aligned vertically. So, I have a padding so that they are all the same length of 4. Problem: the space have smaller width (half in fact) than digits, so alignment is disrupted: Of course, I can use fixed width fonts (like Menlo), but I've not found one that fits (the zero is barred, which is not looking great in the app). I have tried using class func monospacedDigitSystemFont( ofSize fontSize: CGFloat, weight: UIFont.Weight ) -> UIFont and apply to label.text. To no avail as it modifies only digits, not space char. I have found a workaround, padding with 2 spaces instead of one, but is there another solution ? So I am looking for a space character that would have the same width as a digit. There existe thin space (https://en.wikipedia.org/wiki/Whitespace_character) but not larger space. Does it exist ?

We have a big iOS project and we are using .xcconfig files to define our compiler options and build settings. We have our SWIFT_TREAT_WARNINGS_AS_ERRORS set to YES so that all Swift related warnings will be reported as errors. Now, we are trying to migrate to Xcode 16.1 and set 'targeted' in the 'Strict Concurrency Checking' flag. This produces some errors that are related to Swift's concurrency checks. We are now planning to have an approach where we still want to keep SWIFT_TREAT_WARNINGS_AS_ERRORS as is but we want all concurrency related warnings to be still treated as warnings while the rest will get reported as errors. We found this new compiler option - https://forums.swift.org/t/warnings-as-errors-exceptions/72925. It looks like the one we want but I think it is still not out yet and we need to wait until Swift 6.1 (correct me if im wrong). Or is there any other way to do what we want to achieve?

On some production devices our application fails to find the keychain item associated with our application where we store our JWT tokens. We have been unable to reproduce this in house for many months. Today I restored a phone from a backup using the device to device transfer of data as I replaced my personal phone. On that device now when opened each time I am prompted to login again and it appears my token is never saved to the keychain. Upon every successive reopen of the application I see this error in the console. Error fetching keychain item - Error Domain=NSOSStatusErrorDomain Code=-25300 "no matching items found" UserInfo={numberOfErrorsDeep=0, NSDescription=no matching items found} I currently do not see any errors in the console related to the saving of said token. We access this token with the after first unlock security and we do not allow iCloud backup for these tokens. Any help here would be appreciated. I'm not sure what would cause an issue like this. Other applications on my device do not seem to have this issue, so Its likely something we're doing code wise that may be different. Any hints as to what to look for here may be of help. The previous device or any device i have not created from a backup works as intended, including about 95% of our production users.

I'm trying to fix some Swift6 warnings, this one seems too strict, I'm not sure how to fix it. The variable path is a String, which should be immutable, it's a local variable and never used again inside of the function, but still Swift6 complains about it being a race condition, passing it to the task What should I do here to fix the warning?

I'm just trying to display an image that is stored in the local filesystem, but the more I dig into this the more confused I get. So previously I used this code (it's simplified): func findImage(name: String) -> UIImage? { do { let url = try FileManager.default.url(for: .applicationSupportDirectory, in: .userDomainMask, appropriateFor: nil, create: false) .appendingPathComponent("MyFolder") .appendingPathComponent("\(name).png") guard let image = UIImage(contentsOfFile: url.path) else { return nil } return image } catch { print(error.localizedDescription) } return nil } Notice I create the URL with just .appendingPathComponent() and turning URL to path via url.path. It works! So what's the question? In Improving performance and stability when accessing the file system I've read that you better use the new appendingPathComponent(_:isDirectory:), that's good, will do. Also url.path is deprecated in iOS18. Should I use url.path(percentEncoded:) instead? What should be the value of percentEncoded when accessing the local filesystem? In this adjacent thread I've read: Don't use UIImage(contentsOfFile:) either, because it's a path-based API. There's no URL-based equivalent, which is an Apple clue that should be doing something else. Is this true? Then how should I store and load my images? Just FYI, I create images like this: private func generateThumbnail(name: String) { guard let drawingWidth = canvasGeo?.size.width, let drawingHeight = canvasGeo?.size.height else { return } let thumbnailRect = CGRect(x: 0, y: 0, width: drawingWidth, height: drawingHeight) Task { UITraitCollection(userInterfaceStyle: .light).performAsCurrent { let image = self.canvasView.drawing.image(from: thumbnailRect, scale: UIScreen.main.scale) guard let data = image.pngData() else { return } // -- HERE do { try FileManager.default.createDirectory(at: try FileManager.default.url(for: .applicationSupportDirectory, in: .userDomainMask, appropriateFor: nil, create: true) .appendingPathComponent("MyFolder"), withIntermediateDirectories: true, attributes: nil) let filename = "\(name).png" let url = try FileManager.default.url(for: .applicationSupportDirectory, in: .userDomainMask, appropriateFor: nil, create: true) .appendingPathComponent("MyFolder") .appendingPathComponent(filename) try data.write(to: url, options: .atomic) // -- and HERE } catch { print(error.localizedDescription) } } } } My usecase — just save the user's PencilKit Canvas as an image and display it back to him on a different View. I'm on SwiftUI and iOS 16+. Would be happy to learn the correct way, thanks!

I'm pretty new to Swift and SwiftUI. I'm making my first app for sorting a gallery with some extra features. I was using my own iPhone for testing and just started testing my app on other Apple products. Everything works fine on iPad Air M1, iPhone 15 Pro, iPhone 15 Pro Max, iPhone 13, iPhone XS (Simulator), and iPhone 11 Pro (Simulator). However, when I tried to show my app to a family member with an iPhone 11, I came across an issue. Issue Description: My app takes all photos from iPhone's native gallery, then you can sort it by some spesific filters and delete pictures. It just looks like the native gallery. (I can add photos later if needed) You can just scroll the gallery by swiping up and down. You can press the select button and start selecting pictures to delete. I recently added a drag-to-select-multiple-pictures feature. This makes it feel more like the native iOS experience, eliminating the need to tap each picture individually. However, on the iPhone 11, the moment you open the app, you can't scroll. Scrolling is completely locked. You can still select pictures by tapping or dragging, so it's not a touch area issue. The same issue persists on the iPhone 11 simulator. And I think I found the problematic part in my (sadly messy) ContentView.swift file; ScrollView { RefreshControl(coordinateSpace: .named("refresh")) { await viewModel.refreshMediaItems() } LazyVGrid(columns: gridColumns, spacing: UIDevice.current.userInterfaceIdiom == .pad ? 12 : 4) { let items = viewModel.filteredItems(typeFilter: mediaTypeFilter, specialFilter: specialFilter) ForEach(Array(zip(items.indices, items)), id: \.1.id) { index, item in MediaThumbnailView( item: item, isSelected: selectedItems.contains(item.id), viewModel: viewModel, onLongPress: { if !isSelectionMode { toggleSelectionMode() selectedItems.insert(item.id) } }, onTap: { if isSelectionMode { toggleSelection(item: item) } else { viewModel.selectItem(item) } } ) .aspectRatio(1, contentMode: .fit) .background( GeometryReader { geometry in let frame = geometry.frame(in: .named("grid")) Color.clear.preference( key: ItemBoundsPreferenceKey.self, value: [ItemBounds(id: item.id, bounds: frame, index: index)] ) } ) } } .padding(.horizontal, 2) .coordinateSpace(name: "grid") .onPreferenceChange(ItemBoundsPreferenceKey.self) { bounds in itemBounds = Dictionary(uniqueKeysWithValues: bounds.map { ($0.id, $0) }) itemIndices = Dictionary(uniqueKeysWithValues: bounds.map { ($0.id, $0.index) }) } .gesture( DragGesture(minimumDistance: 0) .onChanged { gesture in if isSelectionMode { let location = gesture.location if !isDragging { startDragging(at: location, in: itemBounds) } updateSelection(at: location, in: itemBounds) } } .onEnded { _ in endDragging() } ) } .coordinateSpace(name: "refresh") } you can see the .gesture(.... part. I realised that this DragGesture and ScrollView blocks each other (somehow only on iPhone 11) highPriorityGesture also won't work. When I change it with simultaneousGesture, scroll starts to work again. BUT - since it's simultaneous, when multiple selection mode is activated, when I'm dragging my finger gallery also starts to scroll and it becomes a very unpleasant experience. After this issue I realised on native gallery iOS locks scroll when you are dragging for multiple selection and just when you release your finger you can scroll again even if the multiple selection mode is active. I tried a million things, asked claude, chatgpt etc. etc. Found some similar issues on stackoverflow but they were all related to iOS 18, not spesific to an iPhone. My app works fine on iOS 18 (15 Pro Max) iOS 18 drag gesture blocks scrollview Here are the some of the things I've tried: using highPriorityGesture and simultenousgesture together, tried to lock the scroll briefly while dragging, implement much complicated versions of these things with the help of claude, try to check if isSelectionMode is true or not All of them broke other things/won't work. Probably there's something pretty simple that I'm just missing; but iPhone 11 being the single problematic device confuses me. I don't want to mess too much with my already fragile logic.

I have spent a long time refactoring lots of older Swift code to compile without error in Swift 6. The app is a v3 audio unit host and audio unit. Having installed Sonoma and XCode 16 I compile the code using Swift 6 and it compiles and runs without any warnings or errors. My host will load my AU no problem. LOGIC PRO is still the ONLY audio unit host that will load native Mac V3 audio units and so I like to test my code using Logic. In Sonoma with XCode 16... My AU passes the most stringent AUVAL tests both in terminal and Logic pro. If I compile the AU source in Swift 5 Logic will see the AU, load it and run it without problems. But when I compile the AU in Swift 6 Logic sees the AU, will scan it and verify it passes the tests but will not load the AU. In XCode I see a log message that a "helper application failed to run" but the debugger never connects to the AU and I don't think Logic even gets as far as instantiating the AU. So... what is causing this? I'm stumped.. Developing AUv3 is a brain-aching maze of undocumented hurdles and I'm hoping someone might have found a solution for this one. Meanwhile I guess my only option is to continue using the Swift 5 compiler. (appending a little note just to mention that all the DSP code is written in C/C++, Swift is used mainly for the user interface and also does some offline thready work )

The app I'm making uses the CallDirectory extension to identify callers. Where is the contact data added by "func addIdentificationEntry" in "CallDirectory Extension" stored? The app calls "CXCallDirectoryManager.sharedInstance.reloadExtension" and adds contact data by processing "CXCallDirectoryExtensionContext.addIdentificationEntry" written in "func beginRequest" of "CallDirectory Extension". I thought that if I uninstalled the app, I would lose the contact data that added by App. However, when I uninstalled the app and reinstalled it, it seemed to retain contact data that added by App before I uninstalled the app, even though the app hasn't added any contact data yet. Will the contact data added to the "CallDirectory Extension" be retained on iPhone even after uninstalling the app? ---Note--- I found a similar post on the forum about contact data added by addIdentificationEntry. ・CallKit - addIdentificationEntry is it secure? [https://developer.apple.com/forums/thread/662182] Answer of this post that "the added data is cached in a SQLite database", but I couldn't find any official Apple documentation on this, so I'm not sure if this is correct. If contact data is cached in SQLite, will that data remain on the iPhone when uninstalled and not deleted? ●Development environment Mac OS Sonoma 14.7.1 Xcode 16.0 Swift ●Test Device iPhoneSE3 iOS:17.6.1
