Problem We have successfully set up push notifications using Apple APN service, that is push notifications work when using a token generated using the JSON Web Token Generator in the Push Notification console. However, we get an "InvalidProviderToken" error when creating using our own token using the following code. The Key and TeamID is definitely correct (obviously, censored in the below code). When pasting our token in the JSON Web Token Validator in the Push Notification console we get the error „Invalid signing key“. We merely pasted our secret key in our setNewTokenIfNeeded code, separated on four lines using the “““ style. Does anyone know why this error happens? Given that it works when we upload our .p8 file to the JSON Web Token Generator and we simply paste the text of this file (excluding the lines with "-----BEGIN/END PRIVATE KEY-----") I guess our secret key is correct? Code to generate token fileprivate var currentToken: String? fileprivate var currentTokenCreateTime: Date? fileprivate func setNewTokenIfNeeded() { // Ensure, token is at least 20 minutes but at most 60 minutes old if let currentTokenCreateTime = currentTokenCreateTime { let ageOfTokenInSeconds = abs(Int(currentTokenCreateTime.timeIntervalSinceNow)) NSLog("Age of token: \(Int(ageOfTokenInSeconds / 60)) minutes.") if ageOfTokenInSeconds <= 20 * 60 { return } } // Generate new token NSLog("Renewing token.") let secret = """ ABCABCABCABCABCABCABCABCABCABCABCABC+ABCABC+ABCABCABC+ABCABCAB/+ ABCABCABCABCABCABCABCABCABCABCABCABC+ABCABC+ABCABCABC+ABCABCAB/+ ABCABCABCABCABCABCABCABCABCABCABCABC+ABCABC+ABCABCABC+ABCABCAB/+ ABCABCAB """ let privateKey = SymmetricKey(data: Data(secret.utf8)) let headerJSONData = try!

JSONSerialization.data(withJSONObject: payload, options: .prettyPrinted). Could this be the culprit, given our secret key contains „/„ and „+“? Many thanks!

Hi there We're using CloudKit in our app which, generally, syncs data perfectly between devices. However, recently the sync has stopped working (some changes will never sync and the sync is delayed for several days even with the app open on all devices). CloudKit's logs show the error „You can't save and delete the same record" and „Already have a mirrored relationship registered for this key", etc. We’ve a hunch that this issue is related to a mirrored relationship of one database entity. Our scenario: We've subclassed the database entities. The database model (which we can't share publicly) contains mirrored relationships. We store very long texts in the database (similar to a Word document that contains markup data – in case that’s relevant). Deleting all data and starting with a completely new container and bundle identifier didn’t help (we tried that multiple times). This issue occurs on macOS (15.2（24C101) as well on iOS (18.2). Any hints on how to get the sync working again? Should we simply avoid mirrored relationships? Many thanks

Hi there Issue I've implemented a custom DisclosureGroupStyle for a List, which shows hierarchical data. However, it seems that when applying this (or any other) custom DisclosureGroupStyle in macOS the context menu stops working, except on the lowest level. In iOS, on the other hand, the context menu keeps working on all levels. Is this excepted behaviour? Example     var body: some View {         List(categories, id: \.value, children: \.children) { tree in             Text(tree.value).font(.subheadline)                 .contextMenu{                     Button("Test") {}                 }         }         .disclosureGroupStyle(SideBarDisclosureGroupStyle())         .padding(50)     } } struct SideBarDisclosureGroupStyle: DisclosureGroupStyle {     func makeBody(configuration: Configuration) -> some View {         HStack(alignment: .firstTextBaseline) {             configuration.label             Spacer()             Image(systemName:"chevron.\(configuration.isExpanded ? "down" : "right").circle")                 .imageScale(.large)                 .foregroundStyle(.secondary)                 .onTapGesture() {                     configuration.isExpanded.toggle()                 }         }         .contentShape(Rectangle())                  if configuration.isExpanded {             configuration.content                 .disclosureGroupStyle(self)         }     } } // Example Data (Source: https://swiftwithmajid.com/2020/09/02/displaying-recursive-data-using-outlinegroup-in-swiftui/) struct Tree<Value: Hashable>: Hashable {     let value: Value     var children: [Tree]? = nil } let categories: [Tree<String>] = [     .init(         value: "Clothing",         children: [             .init(value: "Hoodies"),             .init(value: "Jackets"),             .init(value: "Joggers"),             .init(value: "Jumpers"),             .init(                 value: "Jeans",                 children: [                     .init(value: "Regular"),                     .init(value: "Slim")                 ]             ),         ]     ),     .init(         value: "Shoes",         children: [             .init(value: "Boots"),             .init(value: "Sliders"),             .init(value: "Sandals"),             .init(value: "Trainers"),         ]     ) ] System info macOS 13.0 Beta（22A5358e) Xcode 14.0 beta 6 (14A5294g) Many thanks Sebastian

Hello I am trying to display items in a ScrollView which contains several autosized NSViewRepresentables. However, it seems the items overlap each other after scrolling or when the size of its parent ScrollView is changed (for an example see my post on SO) - https://stackoverflow.com/questions/66175613/autosized-nsviewrepresentables-in-scrollview-overlap-each-other-swiftui If I've understood correctly, the ScrollView needs to know the height of its items to render it correctly. Therefore, I tried to pass the total height of the each item to its parent ScrollView, however, the items still overlap. I've made a simple example: struct dataItem: Identifiable { let id = UUID() let question: String let answer: String } let exampleData: [dataItem] = [dataItem(question: "Lorem Ipsum is simply....", answer: "Lorem Ips ange...ker including versions of Lorem Ipsum.") , dataItem(question:"The standard ..ranslation by H. Rackham.", answer:"The standard c.... Rackham."), dataItem(question:"The standard ch...Rackham.", answer:"The stand...kham."), dataItem(question:"The stand..Rackham.", answer:"The standa...kham."), dataItem(question:"The stand...ackham.", answer:"The standard ...ham."), dataItem(question:"The standa..H. Rackham.", answer:"The standard c...ackham."), dataItem(question:"The st... H. Rackham.", answer:"The standard ch...m.") ] struct ContentView: View { @State var totalHeight: CGFloat = 80 var body: some View { ScrollView{ ScrollViewReader{ scrollView in LazyVStack { ForEach(exampleData, id: \.id) { item in RowView(item: item, totalHeight: $totalHeight) // The following line makes the ScrollView jitter // .frame(height: totalHeight) } } } } .id(UUID().uuidString) } } struct RowView: View { let item: dataItem @Binding var totalHeight: CGFloat @State var optimalHeightQuestionValue: CGFloat = .zero @State var optimalHeightAnswerValue: CGFloat = .zero var body: some View{ let optimalHeightQuestion = BindingCGFloat( get: {self.optimalHeightQuestionValue}, set: { self.optimalHeightQuestionValue = $0 totalHeight = optimalHeightQuestionValue + optimalHeightAnswerValue }) let optimalHeightAnswer = BindingCGFloat( get: {self.optimalHeightAnswerValue}, set: { self.optimalHeightAnswerValue = $0 totalHeight = optimalHeightQuestionValue + optimalHeightAnswerValue }) VStack{ TextViewExt(attributedText: NSAttributedString(string: item.question), optimalHeight: optimalHeightQuestion) .frame(height: optimalHeightQuestionValue) TextViewExt(attributedText: NSAttributedString(string: item.answer), optimalHeight: optimalHeightAnswer) .frame(height: optimalHeightAnswerValue) } } } struct TextViewExt: NSViewRepresentable { typealias NSViewType = NSTextView var attributedText: NSAttributedString @Binding var optimalHeight: CGFloat func makeNSView(context: Context) - NSTextView { let textView = NSTextView() textView.backgroundColor = .clear return textView } func updateNSView(_ nsView: NSTextView, context: Context) { DispatchQueue.main.async { nsView.textStorage?.setAttributedString(attributedText) nsView.translatesAutoresizingMaskIntoConstraints = true nsView.sizeToFit() self.optimalHeight = nsView.frame.height } } } Does anybody know why that's happening? Or is there something wrong with the auto-sizing of the NSTextView? Thanks a lot for any advise!
