We have a feature requirement where we need to use LazyVGrid and DropDelegate. Our view hierarchy is as follows: Color.white.ignoresSafeArea() VStack(spacing: 0) { customNavigationView ScrollView(showsIndicators: true) { LazyVGrid(columns: columns, alignment: .center, spacing: 16) { ForEach(viewModel.selectedReferences, id: \.self) { item in ZStack { Rectangle() .fill(Color.yellow.opacity(0.5)) Text(item.title) } .frame (height: 120) .background(Color.white) .padding([.leading, .trailing], 4) .overlay((draggedItem?.uuid == item.uuid && changedView) ? Color.white.opacity(0.8) : Color.clear) .clipShape(RoundedRectangle(cornerRadius: 16, style: .continuous)) .onDrag { initialIndex = viewModel.selectedReferences.firstIndex { $0 == item } draggedItem = item changedView = false return NSItemProvider(object: String(item.uuid) as NSString) } .clipShape(RoundedRectangle(cornerRadius: 16, style: .continuous)) .onDrop(of: [UTType.text], delegate: DragRelocateDelegate(item: item, listData: $viewModel.selectedReferences, current: $draggedItem, changedView: $changedView) { endIndex in }) } } .animation(.default, value: viewModel.selectedReferences) } .frame(width:(UIScreen.main.bounds.width)) .onDrop(of: [UTType.text], delegate: DropOutsideDelegate(current: $draggedItem, changedView: $changedView)) bottomBarView } .frame(maxWidth: .infinity) } While performing a reshuffle, auto-scroll works within the bounds of the ScrollView content. However, according to the feature requirement, auto-scroll should also work when we place an uplifted view at the top or bottom of the view. STEPS TO REPRODUCE Launch the demo. Scroll to the bottom of the LazyVGrid. Pick any item using the DropDelegate. Try to place that uplifted view on the custom navigation view. Expected Result: The ScrollView should auto-scroll. Actual Result: Auto-scroll is not working.

White-label messaging is like a pre-made chat app that one company creates, but other companies can make it look like it’s their own by changing its appearance and name. Basically, it’s a chat tool that businesses can buy and use with their own branding.

Hello we have created a function that is expanding copy module to support html format. Everything inside that function works fine but on 17.4+ IOS version copying the html element strike-through tag is not working (other HTML elements are working fine) . Looking the logs seems like are getting stripped. Here is the code: void copyToClipboard(NSString *htmlContent) { UIPasteboard *pasteboard = [UIPasteboard generalPasteboard]; [pasteboard setValue:htmlContent forPasteboardType:@"public.html"]; } Does anyone know fix for this or when this will be fixed or will it be fixed in next update?

In my case, I open an immersiveSpace and windowGroupA together. When I successfully push a new windowGroupB from windowGroupA, dismissing windowGroupB should return me to windowGroupA. However, this fails, and windowGroupA remains in the background scenePhase. I tried closing immersiveSpace, and it worked successfully. Therefore, pushWindow cannot be used when immersiveSpace is open.

Hi, i am currently updating my app in SwiftUI from iOS 16.4 to 18.0, i am getting in xcode these new warning @State' used inline will not work unless tagged with '@Previewable' so i fix the problem with the suggestions and add the new tag @Previewable and put the variable in the first line of the preview #Preview { @Previewable @State var enabled: Bool = true return NotificationLabel(enabled: $enabled, type: "test", icon: "star", title: "test", description: "test") } the problem is that my app is available from iOS 16.4 to iOS 18.0 and the preview gives me this error 'Previewable()' is only available in iOS 18.0 or newer but if i put a versione if at the top i get another error if #available(iOS 18.0, *){ @Previewable @State var enabled: Bool = true @Previewable' items must be at root scope in the preview block is there a way to silence the warning making a two version preview, one for iOS 18 and one for the previous versions?

I have a punycode link of the following type: https://xn--d1aqf.xn--p1ai/.However, clicking on this link, or opening it through the simulator, opens the page in the browser, not in the application. The system does not see that this domain is present in one of the applications, however, any other domain (example.com , for example), is validated by the system. What could this be related to?

Hi Team, I am having use case where I need to validate/ compare a date received from server with local date. For example I received date from the server is 30th June 2024 And I need to compare the server date is greater than today's date or not. Based on this, I need to allow user to continue access of feature. But iphone user can change the date time of device from iphone's setting option. For example from today to previous month date. So when I tried to compare the server date which I have stored locally is always ahead of today. I can not fetch date from server again and again. How do I get exactly real date even though user has changed device date without fetching from any server?

Actually, I'm developing a new app based on screen time API, so I implemented my report device extension like this struct TotalActivityReport: DeviceActivityReportScene { // Define which context your scene will represent. let context: DeviceActivityReport.Context = .totalActivity // Define the custom configuration and the resulting view for this report. let content: (ActivityReport) -> TotalActivityView func makeConfiguration(representing data: DeviceActivityResults<DeviceActivityData>) async -> ActivityReport { // Reformat the data into a configuration that can be used to create // the report's view. var res = "" var list: [AppDeviceActivity] = [] let totalActivityDuration = await data.flatMap { $0.activitySegments }.reduce(0, { $0 + $1.totalActivityDuration }) for await d in data { res += d.user.appleID!.debugDescription res += d.lastUpdatedDate.description for await a in d.activitySegments{ res += a.totalActivityDuration.formatted() for await c in a.categories { for await ap in c.applications { let appName = (ap.application.localizedDisplayName ?? "nil") let bundle = (ap.application.bundleIdentifier ?? "nil") let duration = ap.totalActivityDuration let numberOfPickups = ap.numberOfPickups let token = ap.application.token let app = AppDeviceActivity( id: bundle, displayName: appName, duration: duration, numberOfPickups: numberOfPickups, token: token ) list.append(app) } } } } return ActivityReport(totalDuration: totalActivityDuration, apps: list) } } Then TotalActivityView to visualize returned data like this // // TotalActivityView.swift // DemoScreenTimeReporter // // Created by Achraf Trabelsi on 17/06/2024. // import SwiftUI import ManagedSettings struct TotalActivityView: View { var activityReport: ActivityReport var body: some View { VStack { Spacer(minLength: 50) Text("Total Screen Time") Spacer(minLength: 10) Text(activityReport.totalDuration.stringFromTimeInterval()) List(activityReport.apps) { app in ListRow(eachApp: app) } } } } struct ListRow: View { var eachApp: AppDeviceActivity var body: some View { HStack { Text(eachApp.displayName) Spacer() Text(eachApp.id) Spacer() Text("\(eachApp.numberOfPickups)") Spacer() Text(String(eachApp.duration.formatted())) if let appToken = eachApp.token { Label(appToken).labelStyle(.iconOnly) } } } } But I got this issue : Cannot convert value of type 'ApplicationToken' (aka 'Token') to expected argument type 'LabelStyleConfiguration' So if anyone have an idea, how can we get application icons please ?

FB13955415 Calls to openURL in iOS 18 beta 22A5282m fails to launch browser. Is this a bug?

Hello, We've a music app reading MPMediaItem. We got items using MPMediaQuery. But we realized that some downloaded tracks from Apple Music were fetched too. Not all downloaded track but only those who were played recently. Of course, since these tracks are protected with DRM we can't play them in our player. It's weird to get them in our query because we added predicate in order to dont fetch protected asset and iCloud item MPMediaPropertyPredicate(value: false, forProperty: MPMediaItemPropertyHasProtectedAsset) MPMediaPropertyPredicate(value: false, forProperty: MPMediaItemPropertyIsCloudItem) To be sure, we made a second check on each item we've fetched extension MPMediaItem { public func isValid() -> Bool { return self.assetURL != nil && !self.isCloudItem && !self.hasProtectedAsset } } But we still get these items. Their hasProtectedAsset attribute always return false. I dont know if it's a bug, but since we can't detect this items as Apple Music downloaded track, we can't either: filter them to not add them in our application library OR switch on a MPMusicPlayerController.applicationMusicPlayer to allow the user to play them

Hi everyone, I'm working on a Vision Pro application and encountering an issue while trying to load a USDZ file.

I have the following struct: Struct Category: Identifiable, Codeable, Hashable { var id: UUID var name: String var subCategory: [Category]? } var categories: [Category] There is no limit how many levels deep the subcategory can be. The user is essentially creating a hierarchical data filing system. Given that the number of subCategory levels is unlimited, I am recursing over the subcategories to find the correct level at which to insert the newCategory. The recursive function to add category is declared as: func recursiveAddCategory(newCategory: Category, subCategoryOf: inout [Category]?) you will note that I am trying to pass the subCategory as a reference (using inout), so that I can add to the original and the function is called as recursiveAddCategory(newCategory, &categories.subCategory!) the actual append statement within the recursiveAddCategory function is: categories.subCategory?.append(newCategory) I am encountering no errors but also find that the newCategory is not being added to the categories array. Any help or guidance appreciated. Thanks

I want to provide my own thumbnails for the file types which System already provides thumbnails for. I tried using QLThumbnailProvider however it works only when the file type is custom. For system supported file types it doesn't allow me to override my own thumbnails. Is there any alternative to this?

Hi everyone, I am developing an application for macOS and need to monitor the network usage (bytes sent and received) of specific processes. Previously, I used the nettop command to achieve this, but I found that it leads to high CPU usage, often reaching 95%. I'm looking for alternative methods to obtain the network usage information of processes. This could be through a different command or an available macOS API. Any suggestions or guidance on more efficient ways to gather this data would be greatly appreciated. Thank you!

I'm experiencing a new error in SwiftData since updating to Xcode 16/iOS 17 DB1. When passing in a model (Student) to a view and then displaying an array of Points using ForEach, I get the following fatal error: SwiftData/ModelCoders.swift:2438: Fatal error: Failed to locate relationship for StringCodingKey(stringValue: "group", intValue: nil) on Entity - name: Point superentity: subentities: storedProperties: CompositeAttribute - name: type, options: [], valueType: PointType, defaultValue: nil Properties: Attribute - name: type, options: [], valueType: String, defaultValue: nil, hashModifier: nil Relationship - name: outcome, options: [], valueType: Outcome, destination: Outcome, inverseName: nil, inverseKeypath: nil CompositeAttribute - name: proficiency, options: [], valueType: Proficiency, defaultValue: nil Properties: Attribute - name: proficiency, options: [], valueType: String, defaultValue: nil, hashModifier: nil Attribute - name: date, options: [], valueType: Date, defaultValue: nil, hashModifier: nil Attribute - name: note, options: [], valueType: String, defaultValue: nil, hashModifier: nil Relationship - name: student, options: [], valueType: Optional<Student>, destination: Student, inverseName: points, inverseKeypath: Optional(\Student.points) Attribute - name: group, options: [], valueType: Array<PersistentIdentifier>, defaultValue: [], hashModifier: nil inheritedProperties: uniquenessConstraints: indices: Xcode flags this line of the macro-generated getter of the outcome property on Point: @storageRestrictions(accesses: _$backingData, initializes: _outcome) init(initialValue) { _$backingData.setValue(forKey: \.outcome, to: initialValue) _outcome = _SwiftDataNoType() } get { _$observationRegistrar.access(self, keyPath: \.outcome) return self.getValue(forKey: \.outcome) // Fatal error: Failed to locate relationship for StringCodingKey... } set { _$observationRegistrar.withMutation(of: self, keyPath: \.outcome) { self.setValue(forKey: \.outcome, to: newValue) } } This worked just fine in iOS 17. Here's a snippet of the Student implementation: @Model class Student: Identifiable, Comparable { var name: String var number: Int @Relationship(deleteRule: .cascade, inverse: \Point.student) var points: [Point] @Relationship(deleteRule: .cascade, inverse: \Mark.student) var marks: [Mark] @Relationship(deleteRule: .nullify, inverse: \StudentGroup.students) var groups: [StudentGroup] = [] var archived: Bool } and the implementation of Point: @Model class Point: Identifiable, Comparable { var student: Student? var type: PointType var outcome: Outcome var proficiency: Proficiency var group: [Student.ID] = [] var date: Date var note: String } and finally the implementation for Outcome: @Model class Outcome: Identifiable, Comparable { var name: String var index: Int var rubric: Rubric? var proficiencies: [Proficiency] } I've tried adding a relationship in Outcome as an inverse of the outcomes property on Points (although this does not make sense in my implementation, which is why I initially did not set a relationship here) and the problem persisted. Any ideas what this error means and how I might go about fixing it?
