Hello, I would like to inquire about the release date of Swift Assist’s beta version. Apple has stated that it will be released later this year, but they have not provided a specific date or time. Could you please provide information on the beta version’s release date? Additionally, is there a trial version available? If so, when was it released? Thank you for your assistance.

Can someone from Apple officially confirm either a delay or cancellation of this feature? 9 days before 2024 ends and Apple said “later this year” in June 2024. Apple mentioned Swift Assist even in the MacBook Pro announcement on the 30th of October 2024 as if it already exists.

In a SwiftUI lab, I was asking about setting the focus state down a view hierarchy. The answer I got was to pass the focus state down the views as a binding. Conceptually, that made sense, so I moved on to other questions. But now that I am trying to implement it, I am having problems. In the parent view, I have something like this: @FocusState private var focusElement: UUID? Then I am setting a property like this in the child view: @Binding var focusedId: UUID? When I try to create the detail view, I'm trying this: DetailView(focusedId: $focusElement) But this doesn't work. The error I get is: Cannot convert value of type 'FocusState<UUID?>.Binding' to expected argument type 'Binding<UUID?>' What is the right way to pass down the focus state to a child view so that it can update back up to the parent view? I am trying to update from one child view, and have a TextField in a sibling view get focus.

Prior to iOS18, the incoming/outgoing call history display in the Phone app matched the CallDirectory content, but starting with iOS18, changing the information tied to the same number results in the incoming/outgoing call history not matching the CallDirectory content, as it remains unchanged before the change. Is this a strongly intended change? If not, we would like to have it reverted back to the way it worked before iOS18. Befor iOS18 Register the target phone number and name1 to CallRirectory Incoming call using the target phone number The target phone number and name1 is recorded as an incoming call history Register the target phone number and name2 to CallRirectory Incoming call using the target phone number again The target phone number and name2 is recorded as an incoming call history Also 1st incoming call history’s name is changed to name2 After iOS18 Register the target phone number and name1 to CallRirectory Incoming call using the target phone number The target phone number and name1 is recorded as an incoming call history Register the target phone number and name2 to CallRirectory Incoming call using the target phone number again The target phone number and name2 is recorded as an incoming call history But 1st incoming call history’s name is still name1 Why does this difference occur?

As per the documentation link, the Tab initializer in SwiftUI should allow supplying a custom view to the Label. However, the colors used within the Label view are not being honored as expected. I attempted to set custom colors in the Label, but they either default to system-defined styles or are ignored entirely. This behavior does not align with my understanding of how custom views should work in SwiftUI's Label. Am I missing a step or configuration here, or is this a bug in the current implementation? struct ContentView: View { @State private var activeTab: TabItem = .homeTab var body: some View { TabView(selection: $activeTab) { ForEach(TabItem.allCases) { tabItem in Tab(value: tabItem) { getView(for: tabItem) } label: { VStack(spacing: 0) { MainTabButtonView( selected: activeTab == tabItem, tabItem: tabItem ) Text(tabItem.title) } } } } } } private extension ContentView { @ViewBuilder func getView(for tabItem: TabItem) -> some View { switch tabItem { case .homeTab: Text("Home") case .searchTab: Text("Search") case .profileTab: Text("Profile") case .moreTab: Text("More") } } } #Preview { ContentView() } enum TabItem: String, Identifiable, Hashable, CaseIterable { case homeTab case searchTab case profileTab case moreTab var tabImage: String { switch self { case .homeTab: "house" case .searchTab: "magnifying-glass" case .profileTab: "biographic" case .moreTab: "hamburger-menu" } } var title: String { switch self { case .homeTab: "Home" case .searchTab: "Search" case .profileTab: "Profile" case .moreTab: "More" } } var id: String { rawValue } } struct MainTabButtonView: View { private let selected: Bool private let tabItem: TabItem init( selected: Bool, tabItem: TabItem ) { self.selected = selected self.tabItem = tabItem } var body: some View { Image(tabItem.tabImage) .renderingMode(.template) .resizable() .aspectRatio(contentMode: .fill) .frame(width: 30, height: 30) .foregroundStyle( selected ? Color.green : Color.orange ) } } Expected Behavior: The custom colors applied within the Label should render as defined. Actual Behavior: The colors are overridden or ignored, defaulting to the system-defined styles. Environment: Xcode Version: Xcode 16.2 iOS: 18.2 Swift Version: Swift 6

Hello, Please guide me if there is a way to show a simple toast to a user that the action has been performed. When a user taps on a button, an api returns a status based on which I need to show appropriate message as a toast. Is this possible in CarPlay? If not, why? Please suggest any alternative for this. Awaiting your response Thanks a lot!!

Hello, I’m trying to change my business model within the app, and following Apple’s documentation guidelines HERE I created this task in the main view of the app. It seems to work perfectly in the simulator, on physical devices, and on TestFlight. However, after releasing it to production and uploading the new version to the App Store, it doesn’t work, and all users, whether new or existing, are asked to subscribe. In the console, it appears to retrieve the transactions correctly, but in production, I’m not sure how to view the console or see what it’s retrieving.

We have found a runtime crash using TipUIPopoverViewController because Xcode didn't warn about its usage when using a deployment target of iOS 16, without a proper #if available verification. In Xcode Version 16.2 (16C5032a), using swift code, TipUIPopoverViewController can be used without if #available(iOS 17, *) without even trigger a warning or compiler error. This is the snippet we're using in a UIViewController, and it compiles without a warning. @objc private func myMethod() { if presentedViewController is TipUIPopoverViewController { // do something } } Of course this triggers a runtime error, specifically, a EXC_BAD_ACCESS. I was expecting that the same way Xcode warns us when we're using Tips and Tips.Status with iOS 16, this would also trigger a compilation error.

Hi everyone, I'm currently working on my own Apple TV app. So far, things are going pretty well, but right now, I'm stuck on the design of the categories or selection menus. Here's a screenshot of how it looks right now: The green color and the border are intentionally added for now so I can see what is where. My actual goal is to remove the gray bar (or is this the "main bar"?). The pink bar and its border are just design elements that can be removed if needed. I want it to look more "original," like this: Here is the code: let title: String let isSelected: Bool var body: some View { HStack { Text(title) .foregroundColor(isSelected ? .black : .white) .font(.system(size: 22, weight: .regular)) .padding(.leading, 20) Spacer() Image(systemName: "chevron.right") .foregroundColor(isSelected ? .black : .gray) .padding(.trailing, 20) } .frame(height: 50) // Einheitliche Höhe für die Kategorien .background(Color.pink) // Innerer Hintergrund auf pink gesetzt .cornerRadius(10) // Abrundung direkt auf den Hintergrund anwenden .overlay( RoundedRectangle(cornerRadius: 10) .stroke(Color.green, lineWidth: 3) // Äußerer Rahmen auf grün gesetzt ) .padding(.horizontal, 0) // Entferne äußere Ränder .background(Color.clear) // Entferne alle anderen Hintergründe } } struct SettingsView_Previews: PreviewProvider { static var previews: some View { SettingsView() } } I’ve adjusted the code, but it’s still not quite right. When a category is not selected, it appears black instead of gray, like in the original design Here is the code: struct SettingsView: View { @State private var selectedCategory: String? var body: some View { NavigationStack { ZStack { Color.black .edgesIgnoringSafeArea(.all) VStack(spacing: 0) { // Überschrift oben in der Mitte Text("Einstellungen") .font(.system(size: 40, weight: .semibold)) .foregroundColor(.white) .padding(.top, 30) HStack { // Linke Seite mit Logo VStack { Spacer() Image(systemName: "applelogo") .resizable() .scaledToFit() .frame(width: 120, height: 120) .foregroundColor(.white) Spacer() } .frame(width: UIScreen.main.bounds.width * 0.4) // Rechte Seite mit Kategorien VStack(spacing: 15) { ForEach(categories, id: \.self) { category in NavigationLink( value: category, label: { SettingsCategoryView( title: category, isSelected: selectedCategory == category ) } ) .buttonStyle(PlainButtonStyle()) } } .frame(width: UIScreen.main.bounds.width * 0.5) } } } .navigationDestination(for: String.self) { value in Text("\(value)-Ansicht") .font(.title) .foregroundColor(.white) .navigationTitle(value) } } } private var categories: [String] { ["Allgemein", "Benutzer:innen und Accounts", "Video und Audio", "Bildschirmschoner", "AirPlay und HomeKit", "Fernbedienungen und Geräte", "Apps", "Netzwerk", "System", "Entwickler"] } } struct SettingsCategoryView: View { let title: String let isSelected: Bool var body: some View { HStack { Text(title) .foregroundColor(.white) .font(.system(size: 22, weight: .medium)) .padding(.leading, 20) Spacer() Image(systemName: "chevron.right") .foregroundColor(.gray) .padding(.trailing, 20) } .frame(height: 50) // Einheitliche Höhe für die Kategorien .background(isSelected ? Color.gray.opacity(0.3) : Color.clear) // Hervorhebung des ausgewählten Elements .cornerRadius(8) // Abgerundete Ecken .scaleEffect(isSelected ? 1.05 : 1.0) // Fokus-Animation .animation(.easeInOut, value: isSelected) } } struct SettingsView_Previews: PreviewProvider { static var previews: some View { SettingsView() } }

I'm encountering an issue displaying a large HTML string (over 11470 characters) in a UILabel. Specifically, the Arabic text within the string is rendering left-to-right instead of the correct right-to-left direction. I've provided a truncated version of the HTML string and the relevant code snippet below. I've tried setting the UILabel's text alignment to right, but this didn't resolve the issue. Could you please advise on how to resolve this bidirectional text rendering problem? The results of the correct and incorrect approaches are shown in the image below. Here's the relevant Swift code: let labelView: UILabel = { let label = UILabel() label.textAlignment = .right label.translatesAutoresizingMaskIntoConstraints = false label.numberOfLines = 0 label.semanticContentAttribute = .forceRightToLeft label.backgroundColor = .white label.lineBreakMode = .byWordWrapping return label }() //Important!! //It must exceed 11470 characters. let htmlString = """ &lt;p style=\"text-align: center;\"&gt;&lt;strong&gt;İSTİÂZE&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;Nahl sûresindeki:&lt;/p&gt; &lt;p dir="rtl" lang="ar"&gt; فَاِذَا قَرَاْتَ الْقُرْاٰنَ فَاسْتَعِذْ بِاللّٰهِ مِنَ الشَّيْطَانِ الرَّج۪يمِ &lt;/p&gt; &lt;p&gt;&lt;strong&gt;“&lt;/strong&gt;&lt;strong&gt;Kur’an okuyacağın zaman kovulmuş şeytandan hemen Allah’a sığın!&lt;/strong&gt;&lt;strong&gt;”&lt;/strong&gt; (Nahl 16/98) emri gereğince Kur’ân-ı Kerîm okumaya başlarken:&lt;/p&gt; &lt;p dir="rtl" lang="ar"&gt;اَعُوذُ بِاللّٰهِ مِنَ الشَّيْطَانِ الرَّج۪يمِ&lt;/p&gt; &lt;p&gt;&lt;em&gt;“Kovulmuş şeytandan Allah’a sığınırım” &lt;/em&gt;deriz. Bu sözü söylemeye “istiâze&lt;em&gt;” denilir. “Eûzü”&lt;/em&gt;, sığınırım, emân dilerim, yardım taleb ederim, gibi anlamlara gelir. It must exceed 11470 characters.&lt;/p&gt; “”” if let data = htmlString.data(using: .utf8) { let options: [NSAttributedString.DocumentReadingOptionKey: Any] = [ .documentType: NSAttributedString.DocumentType.html, .characterEncoding: String.Encoding.utf8.rawValue ] do { let attributedString = try NSAttributedString(data: data, options: options, documentAttributes: nil) labelView.attributedText = attributedString } catch { print("HTML string işlenirken hata oluştu: \(error)") } } I'm using iOS 18.2 and Swift 6. Any suggestions on how to correct the bidirectional text rendering?

I need to render a PDF and then make it downloadable to the mobile device. I can generate the PDF but I'm unsure how to configure the download aspect.

I’m working on a project in Xcode 16.2 and encountered an issue where getAPI() with a default implementation in a protocol extension doesn’t show up in autocomplete. Here’s a simplified version of the code: import Foundation public protocol Repository { func getAPI(from url: String?) } extension Repository { public func getAPI(from url: String? = "https://...") { getAPI(from: url) } } final class _Repository: Repository { func getAPI(from url: String?) { // Task... } } let repo: Repository = _Repository() repo.getAPI( // Autocomplete doesn't suggest getAPI() I’ve tried the following without success: • Clean build folder • Restart Xcode • Reindexing Is there something wrong with the code, or is this a known issue with Xcode 16.2? I’d appreciate any insights or suggestions.

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 ?
