It has been asked several times in the forum, but apple has always maintained that screenshot capture prevention is not supported, how is it that whatsapp and several financial apps are doing it, if screenshot capturing is not possible, its not DRM, is it the adding of a secured text as a layer on to the uiview layer? how have they designed a custom screen if that is the case? Also how is it getting approved by apple! If detection of airplay is possible and can be suppressed, why not screenshot?

We have noticed that in iOS 16 or greater , the Smart App Banner which shows based on meta tag added is not showing the app ratings inside the popup. Can we override this new behavior to show ratings and custom text.

Hello! We're currently testing Live Caller ID implementation and noticed an issue with userIdentifier values in our database. Initially, we expected to have approximately 100 records (one per user), but the database grew to about 10,000 evaluationKey entries. Upon investigation, we discovered that the userIdentifier (extracted from "User-Identifier" header) for the same device remains constant throughout a day but changes after a few days. We store these evaluation keys using a composite key pattern "userIdentifier/configHash". All these entries have the same configHash but different userIdentifier values. This behavior leads to unnecessary database growth as new entries are created for the same users with different userIdentifier values. Could you please clarify: Is this the expected behavior for userIdentifier to change over time? If yes, is there a specific TTL (time-to-live) for userIdentifier? If this is not intended, could this be a potential iOS bug? This information would help us optimize our database storage and implement proper cleanup procedures. Thank you for your assistance!

Dear Apple & Community, I am encountering an issue while running my Unit tests on Xcode 16. I'm receiving the following error in the debugger area.

Hey everyone, First time posting on here. I updated my iPhone 15Pro to 18.4 this morning march 5th, and almost immediately my phone started bugging. Safari won’t load, neither will some of my apps that are heavily data based like Mail. I tried WiFi and data, no difference, I tried different WiFi connections and even a hotspot. Siri and chatGPT also won’t load BUT instagram, Snapchat, TikTok, X, and threads are working perfectly fine. Most games won’t load either. I tried to use a VPN and it has allowed me to access everything that is down Including Siri. This is a temporary solution, hopefully there is a more permanent fix. Thank you all in advance.

How can we advertise custom data through our iOS app using Bluetooth Low Energy advertisement?

Hey everyone, i just updated my IPhone to ios 18.4 a just after i updated my mobile internet stopped working. With no internet i cant do anything, and i dont know how to fix it, i hope someone can help me

Buenos dias: tengo el ultimo iphone 16 plus y desde que hice la ultima actualizacion no me deja desviar las llamadas. Me queda todo el tiempo en procesando.

I already have an opinion ( I should never release to a platform without testing on a physical platform device ) on this but wanted to learn from experience and expertise and see if there were any viable options. My hybrid casual puzzle game is released on the App Store for iOS. (Whew!) Apparently it is compatible to both Mac OS and VisionOS I would love to make it available everywhere however, I am not sure it is best to do so without testing on these physical devices. Which could also mean making the design adjustments for those devices, having test devices ready etc. and I would have to update my Laptop to silicon. Has anyone tried this without testing on physical devices? What are your thoughts/best suggestions? Thanks in advance!

Hello everyone, I've run into a peculiar behavior with UINavigationController's setViewControllers on iOS 18.2 (I guess it might be reproducible on older versions) when reordering view controllers, and I wonder if anyone can shed some light on this issue. Initial State: The navigation stack is [A - B - C]. Without Animation: Setting [A - C - B] updates the stack to: A - C - B as expected. With Animation: Using the same command with animation changes the stack to [A - B], oddly omitting C. Has anyone else noticed similar behavior or knows why animations might disrupt the stack's update this way? I'd appreciate any insights or suggestions. Thanks, Dmytro

I have a Safari extension which allows the user to load their own homepage upon opening a new tab. The extension works by retrieving the homepage URL from UserDefaults and then redirecting to it using window.location.replace. In iOS 18, if the homepage is unable to be loaded due to, for example the user having no internet connection, Safari will go into an rapid loading loop, which eventually stops after a while. This is unlike iOS 17, where trying to reproduce the same scenario will end up with a Safari error page, which should be the expected behaviour. In short, instead of Safari going into an infinite loading loop, it should display a Safari error page like iOS 17 does. As this issue is only happening on iOS 18, I am almost certain it's an iOS bug and would appreciate if this can be fixed as soon as possible. I have created a Feedback Assistant report with ID FB15853821, which contains a sysdiagnose file from my iPhone 16 Pro, as well as two videos, one from my iPhone 16 Pro with iOS 18.2 beta 3 and the other video showing a comparison between iOS 18 and 17. Both videos first show the extension functioning correctly with an active internet connection, but when I disable my internet, the iOS 18 Safari goes into an infinite loop. Here are the steps to reproduce the issue: Download the Homepage for Safari app from the App Store: https://apps.apple.com/gb/app/homepage-for-safari/id6481118559 Enter any valid homepage URL, such as https://apple.com and tap Save Go to Settings -> Apps -> Safari -> Extensions -> Homepage and enable the extension Make sure Open New Tabs is set to “Homepage” Turn off both WiFi and cellular data and attempt to open a new tab in Safari Please note that this also happens with iOS 18.2 beta 4.

De officiële Syrische vlag met twee sterren is vervangen door de huidige Syrische vlag met drie sterren, wetende dat geen enkel land ter wereld de vlag van het land vervangt zonder deze in de grondwet van het land op te nemen. Daarom is het beter om de Syrische vlag met twee sterren te behouden in de volgende iOS 18.4-release, of beide vlaggen samen te voegen, omdat de meeste Syriërs niet de voorkeur geven aan de vlag met drie sterren.

I am developing a flutter app that connects the app to the boat VCU through Wi-Fi. In the iOS version of the mobile app, when the device connects to a Wi-Fi network, iOS assumes that all network traffic should route through Wi-Fi. As the connected Wi-Fi network has no internet access, iOS prompts the user with the options: "Use Mobile Data" or "Keep Trying Wi-Fi." If the user selects "Keep Trying Wi-Fi," mobile data will not be used by other apps on the phone. If the user selects "Use Mobile Data," the app switches to mobile data while remaining connected to the Wi-Fi network (VCU) without any issues. The issue is we need to find a way to prevent showing that prompt and instead handle this through code. After connecting to VCU, the mobile network is available for a few second but then it switches to wifi and no internet! I checked all the online documentation but there is not any solution for it. So, I need to stay connect to vcc and other apps use mobile data. I tried WiFiForIoTPlugin.forceWifiUsage(false); but didn't work. I tried adding delay that also didn't work. This is the function in my code that handles connecting to Wi-fI: Future connectToWifi() async { try { if (Platform.isAndroid) { isConnected = await WiFiForIoTPlugin.connect( _vesselData['ssid'], password: _vesselData['passphrase'], security: NetworkSecurity.WPA, // Enable Internet access withInternet: false, isHidden: true, timeoutInSeconds: 10, joinOnce: true, ); // Force Android to treat Wi-Fi as the primary network using await WiFiForIoTPlugin.forceWifiUsage(true); } else if (Platform.isIOS){ isConnected = await WiFiForIoTPlugin.connect( _vesselData['ssid'], password: _vesselData['passphrase'], security: NetworkSecurity.WPA, isHidden: true, timeoutInSeconds: 10, // Ensures the connection remains persistent, preventing the system from disconnecting the device. joinOnce: false, ); } if (isConnected) { log("Connected to ${_vesselData['ssid']}"); streamData(); } else { log("Failed to connect to ${_vesselData['ssid']}"); } } catch (e) { log("Error: $e"); } } I use :Device Model: iPhone 12 Pro Max iOS Version: iOS 18.3.1 Xcode Version: Xcode 16.2 Mac Version: macOS Sonoma 14.3

I have an application named "XY" that has been launched in several countries. Now, I intend to launch it in Turkey, but we are facing legal issues preventing us from using "XY" as the app's display name. Following the documentation, I localized the app's display name to "ZX" for both Turkish and English (Turkey). However, when users change their device settings, they do not see an option for English (Turkey) language selection. I assumed that for Turkish users, English (Turkey) would be the default language, but this is not the case. Could someone please assist me in resolving this issue? I've investigated options for localizing the display name based on region, but it seems that this functionality isn't feasible on iOS. In contrast, it's relatively straightforward to achieve on Android platforms.

I'm working on the control widget which should display the SF image on the UI, but I have found that it cannot be displayed stably. I have three ExampleControlWidget which is about the type egA egB and egC, it should all be showed but now they only show the text and placeholder. I'm aware of the images should be SF image and I can see them to show perfectly sometimes, but in other time it is just failed. This's really confused me, can anyone help me out? public enum ControlWidgetType: Sendable { case egA case egB case egC public var imageName: String { switch self { case .egA: return "egA" case .egB: return "egB" case .egC: return "egC" } } } struct ExampleControlWidget: ControlWidget { var body: some ControlWidgetConfiguration { AppIntentControlConfiguration( kind: kind, provider: Provider() ) { example in ControlWidgetToggle( example.name, isOn: example.state.isOn, action: ExampleControlWidgetIntent(id: example.id), valueLabel: { isOn in ExampleControlWidgetView( statusText: isOn ?

HI, I am currently prototyping an app that compares transport protocol performances using a peer to peer connection. I have already setup TCP and UDP connections and am sending data between the clients, it works like I want it to. Next I was trying to setup a connection using QUIC, but the NWConnection.State stays in the preparing state and I couldn't find a way to get more information from the framework or the instances about why it was not fully connecting. After searching the internet and stumbling across the forum I noticed that the missing encryption might be the issue, so I created a local root certificate*. Then I used the SecPKCS12Import function to read/extract the SecIdentity instance of the p12 file (cert + private key) stored in my bundle** and set it as a local identity with the sec_protocol_options_set_local_identity function***. //function that creates/returns different NWParameteres //... let quicOptions = NWProtocolQUIC.Options() quicOptions.alpn = ["test"] if let identityPath = Bundle.main.path(forResource: "QUICConnect", ofType: "p12"), let identityData = try? Data(contentsOf: URL(fileURLWithPath: identityPath)) { if let identity = loadIdentityFromPKCS12(p12Path: identityPath, password: "insecure") { //**** sec_protocol_options_set_local_identity(quicOptions.securityProtocolOptions, sec_identity_create(identity)!) } } let parameters = NWParameters(quic: quicOptions) parameters.includePeerToPeer = true return parameter The documentation comments had me thinking that setting a local identity could be enough, since it consists of the private key for the "server" and the cert for the "client". Set the local identity to be used for this protocol instance. Unfortunately at this stage the QUIC Connection is still stuck in preparing state and since I don't know how to extract more information from the networking connection instances/framework, I am stuck. I have seen the following other functions in Quinns answer and am confident that I could somehow figure it out with some more time put into it, but not really understanding why or how I could do it better in the future. So I am also wondering how I could have found info about this more efficiently and tackled this more strategically without needing to browse through so many forums. sec_protocol_options_set_verify_block sec_protocol_options_set_challenge_block I would really appreciate any help, many thanks. BR Matthias! TLDR: I want to establish a peer to peer QUIC Connection but the state is stuck in preparing. Secondary question is how I could approach a similar topic more efficiently next time, instead of browsing many forums. * I had to create it with the openssl CLI since the keychain app created a cert, that when using the openssl CLI to get the info would throw an error unless used with the -legacy flag. The root cert, created form the keychain app also wasn't able to be imported by the SecPKCS12Import function. No clue why but it worked with a cert created from the openssl CLI. There's a chance that I messed up something else here, but these were my experiences. Info: Since QUIC is limited to TLS v1.3 I can't use PSK, afaik. Therefore the TicTacToe doesn't help me anymore. ** I know this is highly insecure, I am just using it for prototyping. *** Forum users Info: One needs to use the sec_identity_create function to convert the SecIdentity instance to the expected parameter type. **** func loadIdentityFromPKCS12(p12Path: String, password: String) -> SecIdentity? { guard let p12Data = try? Data(contentsOf: URL(fileURLWithPath: p12Path)) else { print("didnt find p12 file at path") return nil } let options: NSDictionary = [kSecImportExportPassphrase as String: password, kSecImportToMemoryOnly as String: kCFBooleanTrue!] var items: CFArray? let status = SecPKCS12Import(p12Data as CFData, options, &items) if status == 0, let dict = (items as? [[String: Any]])?.first { if let identity = dict[kSecImportItemIdentity as String] { return identity as! SecIdentity } else { return nil } } else { return nil } } PS: For TCP and UDP I am using bonjour to discover the peer and connect to the advertised ports. AFAIK I can't just use _testproto._quic to advertise a QUIC service like with tcp and udp. Therefore I am using the local domain name (it's just for prototyping and always the same device) and a hard coded port number to create the peer connection. When using a wrong name the DNS threw an error telling it could not find a peer, so the lookup itself is working I guess. The lookup should come from the cache since I already looked up when connecting to the same peer via Bonjour. //Server //.... listener = try NWListener( using: transportProtocol.parameters, on: Config.quicPort ) //... listener.newConnectionHandler = { [weak self] connection in self?.connection?.cancel() self?.connection = nil self?.connection = C(connection) //here C is a generic that conforms to a custom connection interface, nothing to worry about :) self?.connectionStatus.value = "Connection established" } listener.stateUpdateHandler = { [weak self] state in self?.connectionStatus.value = "\(state)" } listener.start(queue: .global()) //Client //... nwConnection = NWConnection(host: "iPad.local.", port: Config.quicPort, using: transportProtocol.parameters) //...

Hi Apple Developers, I am currently working on a message filtering application and facing issues specifically with filtering RCS (Rich Communication Services) messages. To debug this, I created a sample app that consistently categorizes all incoming messages as "junk." However, the filtering behaviour is inconsistent and not functioning as expected. Here are the key issues observed during testing on iOS versions 18.2.1 and 18.3: Inconsistent Filtering Behavior: When a message is received from an unknown number, it sometimes gets moved to the Junk folder momentarily but is then immediately moved back to the main Messages inbox. In some cases, the message does not get moved to the Junk folder at all, despite the app returning the verdict as "junk." Duplicate Contact Tiles: The Messages app displays two separate conversation tiles for the same mobile number, which is unexpected behavior. I have attached both a sample app and a screen recording that clearly demonstrates the issue. The recording shows that the app categorizes messages as junk, yet they still end up in the main Messages inbox. For reference, my carrier partner is T-Mobile. Please let me know if you need any additional information to investigate this issue further. Looking forward to your insights and guidance. Best regards, Rijul Singhal

With the Live Caller ID example server, the caller lookup dataset is defined in an input.txtpd and processed by running a ConstructDatabase command which creates a block.binpb and an identity.binpb file. In other words, a static input file is being processed into static block and identity files. However, in the real world, the data content for identified and blocked numbers is something which is in a constant state of flux and evolution, as new numbers becoming available, old ones become stale, numbers which were initially considered safe change into being considered malicious etc. etc. Is the example server just that, merely an example using fixed datasets, and an actual production server is able to use live every changing data to formulate its response back to the iPhone OS query? Here's a concrete use case - suppose it's a requirement to permit US nanp numbers but to block anything else. The total number of non US nanp numbers is so large and ever changing that it would be unfeasible to attempt to capture them in an input.txtpd file and then process that, and then to re-capture and re-process it endlessly. Instead what would be required is the ability for the Live Caller ID server to evaluate at query time, using a regular expressions for example, if a number is nanp or not. Is this possible?
