Hi, I was testing the lockdown mode in iOS 16 and would like to know whether we can detect the lockdown mode status using any public API that Apple provides. I really appreciate any help you can provide.

Facing issue of NSUserDefaults data got cleared on update new version from app store. so all data of user got cleared and user have to login again. I was having app in store with version 1.1.3 and then we have uploaded new version to store with version 1.1.4 but when user download app from store their data was cleared from UserDefaults.so this is big issue in update. need to help. is that apple updated any process on update. Question How Apple change version build in device when we update app from app store. is it uninstall old build and install new build ? Or it is install new version on old version ? Should UserDefaults.standard will delete on update ? Updating Provisioning profile from manual to automatically cause issue on UserDefaults.standard Like UserDefaults got cleared and uuid will change ? Do we have anythings that we can identify specific user as uniq user ? What is better solution to store login data into SQLite store or in UserDefaults as model ? Will appreciate for your help. this is very big issue and login again on update will make app user more effect

When I startAdvertising, my localName is long, more than 8 bytes. like @"123456789".    [_peripheralManager startAdvertising:@{             CBAdvertisementDataLocalNameKey: @"123456789",             CBAdvertisementDataServiceUUIDsKey: @[[CBUUID UUIDWithString:@"bbbb14c7-4697-aaaa-b436-d47e3d4ed187"]]             }]; When running on macOS 11.x though localName exceeds 8 bytes. But it can still be scanned. {   kCBAdvDataIsConnectable = 1;   kCBAdvDataLocalName = 123456789;   kCBAdvDataRxPrimaryPHY = 0;   kCBAdvDataRxSecondaryPHY = 0;   kCBAdvDataServiceUUIDs =   (     "BBBB14C7-4697-AAAA-B436-D47E3D4ED187"   );   kCBAdvDataTimestamp = "680712553.800874";   kCBAdvDataTxPowerLevel = 12; } But running after macOS 12.x, if localName exceeds 8 bytes, it will be completely ignored. In the scanned data, localName is empty. {   kCBAdvDataIsConnectable = 1;   kCBAdvDataRxPrimaryPHY = 0;   kCBAdvDataRxSecondaryPHY = 0;   kCBAdvDataServiceUUIDs =   (     "BBBB14C7-4697-AAAA-B436-D47E3D4ED187"   );   kCBAdvDataTimestamp = "680712744.108894";   kCBAdvDataTxPowerLevel = 12; } On macOS11.x, SCAN_RSP is utilized if localName exceeds 8 bytes, while on macOS12.x, SCAN_RSP is always empty. Why are there differences between macOS11.x and macos12.x, is there any documentation? What is the maximum limit for localName? (On macOS 11.x, I verified it was 29 bytes Are there other ways to broadcast longer data? Does anyone know why? This has bothered me for a long time...

Hi, In my apps, the recent iOS 16.0 beta 7 (20A5356a) broke the .timer DateStyle property of the Text view, in a SwiftUI widget. In previous OS and beta, Text(Date(), style: .timer) was correctly displaying an increasing counter. In iOS 6.0 beta 7, Text(Date(), style: .timer) does not update anymore, (and is offset to the left). The other DateStyle (like .offset, .relative, ...) seems to update correctly. Anyone noticed that (very specific) problem ?

I'm trying to implement Unwanted SMS and Calls reporting in an app I'm doing in my idle time. If I place a UITextField or UITextView inside a ILClassificationUIExtensionViewController, every time I select on such control the extension crashes without any logs. The closet idea I have on why it crashes it has something to do with iOS requesting the dictation feature. I'm using the latest (beta 8 at the time) iOS 16.0 beta on my iPhone 13 pro. Attaching my code here if you want to try for yourself: github

My team has been debugging problems with the SwiftUI List component this week. We have found that it's performance is sub-optimal on iOS 16. You can see a simple grid of images, the scroll indicator stutters when scrolling down: Now compare it to what happens when we use a ScrollView with a LazyVStack: (An error occurred while uploading my second image, but pretend you see a scroll indicator moving smoothly down the side of the screen). You can see the scroll indicator moves smoothly without issue. We also found that the ScrollView combined with a LazyVStack properly calls onDisappear, which enables us to call a cancel method on the async image loading code that we use for our individual cells in this example. Though in a previous question, it was asserted that onDisappear cannot be reliably expected to be called in a List, I do not feel that answer is correct or proper behavior. Is this a bug, or is this expected behavior on a List? This is the cell that is being rendered: struct UserGridCell: View {   let stackId: String   let user: ProfileGridCellUIModel   let userGridCellType: UserGridCellType   @State var labelFrame: CGRect = .zero       private var isOnlineAcessibilityValue: String {     return user.isOnline == true ? "" : ""   }       init(stackId: String,      user: ProfileGridCellUIModel,      userGridCellType: UserGridCellType   ) {           self.stackId = stackId     self.user = user     self.userGridCellType = userGridCellType   }   var body: some View {     GeometryReader { containerGeometry in       ZStack(alignment: .bottom) {         HStack(spacing: 4) {                       let statusAccentColor: Color = .red                                   Circle()             .frame(width: 8, height: 8)             .foregroundColor(statusAccentColor)                       Text(String(user.remoteId) ?? "")             .lineLimit(1)             .foregroundColor(.black)             .overlay(GeometryReader { textGeometry in               Text("").onAppear {                 self.labelFrame = textGeometry.frame(in: .global)               }             })         }         .frame(maxWidth: .infinity, alignment: .bottomLeading)         .padding(.leading, 8)         .padding(.trailing, 8)         .padding(.bottom, 8)       }       .frame(maxWidth: .infinity, maxHeight: .infinity, alignment: .bottom)       .contentShape(Rectangle())       .accessibilityLabel(Text(user.name ?? ""))       .accessibilityValue(isOnlineAcessibilityValue)     }     .background(       ZStack {         AsyncProfileImage(request: URLRequest(url: URL(string: "https://picsum.photos/id/\(100 + user.remoteId)/200/300")!))       }         .accessibilityHidden(true)     )     .overlay(       RoundedRectangle(cornerRadius: 4)         .stroke(.red, lineWidth: user.hasAnyUnreadMessages ? 4 : 0)     )     .cornerRadius(4)   } } This is the code that renders each cell: struct ProfileGrid: View {   public static var AspectRatio: CGFloat = 0.75   @Environment(\.horizontalSizeClass) var horizontalSizeClass   @Environment(\.redactionReasons) private var reasons   private let stacks: [ProfileGridStackUIModel]   public init(stacks: [ProfileGridStackUIModel]   ) {     self.stacks = stacks   }       var body: some View {     let columnCount: Int = 3           // If you use a list, you will get the stutter. If you use what you see below, // it will render properly.     ScrollView {       LazyVStack {         ForEach(stacks, id: \.self) { stack in           Grid(stack: stack, columns: columnCount)         }       }     }     .buttonStyle(PlainButtonStyle())     .listStyle(PlainListStyle())   }       @ViewBuilder private func Grid(stack: ProfileGridStackUIModel, columns: Int) -> some View {     let chunks = stride(from: 0, to: stack.profiles.count, by: columns).map {       Array(stack.profiles[$0..<min($0 + columns, stack.profiles.count)])     }                   ForEach(chunks, id: \.self) { chunk in       GridRow(chunk: chunk, stack: stack, columns: columns)         .listRowInsets(EdgeInsets(top: 0, leading: 0, bottom: 0, trailing: 0))     }   }       @ViewBuilder private func GridRow(chunk: [ProfileGridCellUIModel], stack: ProfileGridStackUIModel, columns: Int) -> some View {     let emptyElements = columns - chunk.count     HStack(spacing: 8) {       ForEach(chunk) { user in         UserGridCell(stackId: "id",                user: user,                userGridCellType: .grid)         .aspectRatio(ProfileGrid.AspectRatio, contentMode: .fill)       }               if emptyElements > 0 {         ForEach(0..<emptyElements, id: \.self) { _ in           Rectangle()             .foregroundColor(Color.clear)             .contentShape(Rectangle())             .frame(maxWidth: .infinity)             .aspectRatio(ProfileGrid.AspectRatio, contentMode: .fill)         }       }     }   } }

Hello, maybe anyone know anything about HCE (Host card emulation) feature on iOS? As far as I read, it's not possible to achieve this functionality on iOS, but maybe there are plans to implement that? Or maybe it's clear that it wont be allowed to be used at all? Thanks:)

Hi, we've observed a weird behavior for a small amount of our user that we keep receiving the same token from APNs despite it's shown as Unregistered. When we try to send push to the token, we got an Unregistered error so we remove that token from our server. However, later we would receive an add token request from the client with the same token we just removed, and when we try to send to the token it returns Unregistered again so we remove the token again. This happened 3 times for a user in an hour. The identifierForVendor remains the same for all the requests. We also owns the client and I've checked client code that it's sending the token it received from didRegisterForRemoteNotificationsWithDeviceToken to the server.

The documentation for CGColorRef (https://developer.apple.com/documentation/coregraphics/cgcolorref?language=objc) clearly shows that it is a struct. However, when I try to store a cell's border color using CGColorRef originalColor = self.bg.layer.borderColor and inspect what happens in the debugger, both that property and its copy have the same address. And later when I try to restore the border color the copy still has the same address but is no longer valid and causes a crash on assignment (originalColor is actually an instance variable...) This is all object behavior, not struct behavior. If CGColorRef really was a struct, the contents would have been copied, the instance variable would have had its own address that would never have changed, and the value would have remained valid indefinitely and let me copy it back without a problem. Why is this documented wrong? Was this a recent change? I actually had this code working at some point, and now it's broken.

We are integrating iOS 16 recurring payments in our app, everything works fine but we have a few questions Question 1 let recurringPaymentRequest = PKRecurringPaymentRequest(         paymentDescription: "Pro Membership",         regularBilling: regularBilling,         managementURL: url       ) we assume managementURL is supposed to come in the user's wallet where he/she can tap to change the recurring payment option to our backend, but in the wallet, the transaction appears without this URL and have no indication that it is a recurring payment, Can someone guide what we missed Question 2 For apps that only have apple pay on mobile, managementURL can open the app as a deep link from the Wallet app and the user can update or delete the payment method for the automatic reload payment from the app directly, Question 3 For cancellation, the recurring payment app should have some UI where the user can tap which hit our backend and remove the apple pay merchant token from our system and apply cancellation business logic, no apple API involves in the cancellation of recurring payment

My team recently released an app to the iOS app store. We are trying to add the Smart App Banner to our website to promote the app, but the banner is not shown. When the page loads, there is a flash of an empty Smart App Banner before it is automatically dismissed. This happens on every page load. If I put use an app ID of other apps the banner appears. I've triple checked that I'm using the correct app ID. So it seems like it is an issue with my app. I can see my app in the App Store, so I know it's available. I've tested on multiple phones.

In App Store Connect I've uploaded a new build about 11 hours ago and but I'm unable to distribute the App to my tester groups - including internal. The internal group is grayed out. I am able to Select an External group but they actually do not receive any email notification nor do they see any update within their TestFlight App. I've attempted to upload the build a few times, including old builds which had been distributed in the past to no avail. I'm not able to distribute to any tester group, please advise.

Generic parameter 'V' could not be inferred ERROR

The device UDID was registered to the developer account 40 hours ago, the STATUS column was "processing" in the first 24 hours, then turned to empty. But I still can't run my app (with distribution method "development"), when I try to run it after download it through my OTA URL, it prompts “the app cannot be installed because its integrity could not be verified” but everything runs good on a iPhone which was registered a month ago. What should I do now? keep waiting?

I have a project that need to get serial number and network SSID. I have looking anywhere to get those 2 value but no luck to find it. is there anyway i can get those information from the device?

Please excuse my lack of understanding of what are probably fundamental concepts in iOS/iPadOS development but I have searched far and wide for documentation and haven't had much luck so far. I am not sure that what I want to do is even possible with an iPad iPadOS app. Goals: Develop a Swift iPadOS app that can digitally sign a file using a PIV SmartCard/Token (Personal Identity Verification Card): Insert a PIV SmartCard/Token (such as a Yubikey 5Ci) into the lightning port of an iPadOS device iPad (NOT MacOS) Interface with the SmartCard/Token to access the user's PIV certificate/signature and "use it" to sign a file Question 1: How to get the PIV Certificate from SmartCard/Token/Yubikey into iPadOS keychain?   * Do we need to get the PIV certificate into the iOS keychain? Is there another way to interact with a SmartCard directly?   * This should prompt the user for their PIN? Question 2: How to get our Swift app to hook into the event that the SmartCard/Token is inserted into the device and then interface with the user's certificate?   * When is the user prompted to enter their PIN for SmartCard/Token/Yubikey?   * Do we need to use CyrptoTokenKit to interface with a smartcard inserted into the lightning port of an iOS device?

Hi Apple, Currently we want to have enhancement for SMS OTP that we want to implement OTP Autofill, But after do some research we're stuck with option that the OTP only show in keyboard suggestion, is there any way for making OTP is automatically filled without user have to click the keyboard suggestion when receiving the SMS. Thanks Best Regards, Admiral Sultano Harly.

I'd like to know the install state of my iOS safari extension in the associated swift app. Is there any way to get this? As we have seen it is available for macOS here, is there anyway to know iOS Safari extension is enabled or not? Thanks

On iPads after updating to iPadOS 16.4, Safari often "looses" the session cookie provided by PlayFramework: When the browser requests assets (js scripts) or when additional data is fetched by JavaScript, the session cookie is not included in the request. These secondary requests will redirect through our IAM because no session cookie is present. The IAM redirects back to the original domain with a payload so that the login session can be resumed. A new Set-Cookie header is sent in the response with the new session cookie. This causes the framework to issue a new CSRF token (that is part of the session cookie) which is different from the old one that was already rendered into a hidden form input. The browser stores this new token and includes it when it POSTs the form. The token in the body of the request is now different from the one in the cookies, causing the CSRF check to fail. We have tried different devices (Android, Windows, MacBook, and iPads) on different versions. The problem only occurs with Safari on iPad/MacBook running version 16.4, 16.4.1, or 16.5 beta. The problem cannot be reproduced using Chrome on iPad. Furthermore, the problem does not occur with private browsing in Safari. Some things we ruled out: Same behaviour on devices managed by MDM and on open devices. PlayFramework version is now updated to the latest 2.8 version. Using a separate cookie for the CSRF token (instead of the play session cookie) does not make a difference either. Modifying the Cache-Control header to cache responses more aggressively or not at all does not help. Has anyone also experienced this or similar problems?
