Good day, this is a concept maybe newbie question… what would be the best approach to develop the real time app… what I want is to be able to connect one device to other one within the app, and for example, if the app has a draggable object, then if one user drags the object, the other user see the object moving in real time I his own device, maybe using a ghost mode when interacting… this way both users using the app can interact with the objects in real-time. It’s not a game, so there’s no score… could I use gamecenter? or multipeer connectivity over BT? Is there a native framework? wich would be the easiest and less battery and system consuming approach someone could suggest? thank you in advance….

I have installed the following configuration profile: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>PayloadContent</key> <array> <dict> <key>PayloadDisplayName</key> <string>Enable Private Data Logging for Unified Logging</string> <key>PayloadEnabled</key> <true/> <key>PayloadIdentifier</key> <string>com.apple.system.logging.2BFB8109-8829-4020-AEB7-BA21761AE50C</string> <key>PayloadType</key> <string>com.apple.system.logging</string> <key>PayloadUUID</key> <string>2BFB8109-8829-4020-AEB7-BA21761AE50C</string> <key>PayloadVersion</key> <integer>1</integer> <key>System</key> <dict> <key>Enable-Private-Data</key> <true/> </dict> </dict> </array> <key>PayloadDisplayName</key> <string>Enable Private Logging Data</string> <key>PayloadIdentifier</key> <string>Kentzo-Macbook.D000DF5D-AE7A-4D22-B1DC-8F9CD71A2DD2</string> <key>PayloadRemovalDisallowed</key> <false/> <key>PayloadType</key> <string>Configuration</string> <key>PayloadUUID</key> <string>1CF75441-D3C2-4E5B-B36A-394C397E8529</string> <key>PayloadVersion</key> <integer>1</integer> <key>ConsentText</key> <dict> <key>default</key> <string>Warning: Installing this profile will enable private data logging for all of unified logging.</string> </dict> </dict> </plist> But both Console.app and log show values like <mask.hash: 'Z9xIxlLTn0KlWPUjmpOSkg=='> for the com.apple.mDNSResponder subsystem.

I'm using NWBrowser to search for a server that I hosted. The browser does find my service but when it tries to connect to it, it gets stuck in the preparing phase in NWConnection.stateUpdateHandler. When I hardcode the local IP address of my computer (where the server is hosted) into NWConnection it works perfectly fine and is able to connect. When it gets stuck in the preparing phase, it gives me the warnings and error messages in the image below. You can also see that the service name is correct and it is found. I have tried _http._tcp and _ssh._tcp types and neither work. This is what my code looks like: func findServerAndConnect(port: UInt16) { print("Searching for server...") let browser = NWBrowser(for: .bonjour(type: "_ssh._tcp", domain: "local."), using: .tcp) browser.browseResultsChangedHandler = { results, _ in print("Found results: \(results)") for result in results { if case let NWEndpoint.service(name, type_, domain, interface) = result.endpoint { if name == "PocketPadServer" { print("Found service: \(name) of type \(type_) in domain \(domain) on interface \(interface)") // Construct the full service name, including type and domain let fullServiceName = "\(name).\(type_).\(domain)" print("Full service name: \(fullServiceName), \(result.endpoint)") self.connect(to: result.endpoint, port: port) browser.cancel() break } } } } browser.start(queue: .main) } func connect(to endpoint: NWEndpoint, port: UInt16) { print("Connecting to \(endpoint) on port \(port)...") // endpoint = NWEndpoint( let tcpParams = NWProtocolTCP.Options() tcpParams.enableFastOpen = true tcpParams.keepaliveIdle = 2 let params = NWParameters(tls: nil, tcp: tcpParams) params.includePeerToPeer = true // connection = NWConnection(host: NWEndpoint.Host("xx.xxx.xxx.xxx"), port: NWEndpoint.Port(3000), using: params) connection = NWConnection(to: endpoint, using: params) connection?.pathUpdateHandler = { path in print("Connection path update: \(path)") if path.status == .satisfied { print("Connection path is satisfied") } else { print("Connection path is not satisfied: \(path.status)") } } connection?.stateUpdateHandler = { newState in DispatchQueue.main.async { switch newState { case .ready: print("Connected to server") self.pairing = true self.receiveMessage() case .failed(let error): print("Connection failed: \(error)") self.isConnected = false case .waiting(let error): print("Waiting for connection... \(error)") self.isConnected = false case .cancelled: print("Connection cancelled") self.isConnected = false case .preparing: print("Preparing connection...") self.isConnected = false default: print("Connection state changed: \(newState)") break } } } connection?.start(queue: .main) }

I have my both app and fskit sandboxed &lt;key&gt;com.apple.security.app-sandbox&lt;/key&gt; &lt;true/&gt; Which means that I can read files only in app container. First, is sandboxing required for fskit modules? Second, there are docs which implies that it's possible to explicitly allow fskit module to access external files, by passing their paths to mount params. https://developer.apple.com/documentation/fskit/fstaskoptions/url(foroption:) and also options: Options to apply to the activation. These can include security-scoped file paths. There are no defined options currently. I've tried this, but haven't success. My Info.plist is &lt;key&gt;FSActivateOptionSyntax&lt;/key&gt; &lt;dict&gt; &lt;key&gt;shortOptions&lt;/key&gt; &lt;string&gt;g:m:&lt;/string&gt; &lt;key&gt;pathOptions&lt;/key&gt; &lt;dict&gt; &lt;key&gt;m&lt;/key&gt; &lt;string&gt;file&lt;/string&gt; &lt;key&gt;g&lt;/key&gt; &lt;string&gt;directory&lt;/string&gt; &lt;/dict&gt; &lt;/dict&gt; I'm mounting with mount -F -t MyFS -o -m=./build.sh,-g=./ /dev/disk5 /tmp/TestVol Getting them via options.url(forOption: "m"), options.url(forOption: "g") Both nulls. I also see that options are presented in options.taskOptions But they are not expanded to absolute pathes or urls, which makes me think that pathOptions declaration is incorrect. Docs says This dictionary uses the command option name as a key, and each entry has a value indicating what kind of entry to create. What entry kind means in this context? Can you send example of correct pathOptions?

I would like to know whether and how people are getting the sandbox account > manage > clear purchase history feature to work. I clear purchase history (either on my device or at app store connect), and I delete my app from my device. I then run my app from Xcode on my device, and it detects at launch the existence of the purchase, and so I cannot test my purchase user interface. Does this thing actually work as advertised?

Dear community, Context My company operates in the European Union, where not so long ago there appeared the possibility to accept an ["Alternative Terms Addendum for Apps in the EU"] (https://developer.apple.com/contact/request/download/alternate_eu_terms_addendum.pdf), which, among others, gives us the possibility to use an alternative payment provider, other than Apple's In App Purchase PSP system (ref: Apple docs). My company did accept it and was granted the StoreKit External Purchase Entitlement (com.apple.developer.storekit.external-purchase) entitlement, with which we integrated a different PSP, so now we want to incorporate the reporting to Apple's External Purchase Server API. We are currently integrating with the External Purchase Server API and have encountered a couple of issues I would appreciate clarification on: Question 1 Is there a way to retrieve an overview or summary of the current subscription states on Apple’s servers as a result of the submitted reports to External Purchase Server API? Specifically, I would like to verify the expected outcomes before the monthly invoice is issued by Apple and to understand the subscription states for the test users I used during this process and for future reference as well. Question 2 In one scenario, I initiated a one-year subscription, and in the middle of its period, I submitted a RENEWAL for one month with a higher price. I expected the request to fail due to overlapping periods and/or pricing conflicts, but both submissions were accepted without error. Do you have an idea about: What happens at the end of the renewed month? Will the subscription continue with the renewed (higher) amount, revert to the original (lower) annual rate, or be canceled? Where can I view the final state and billing plan for that subscription? Thank you for your assistance, we are looking forward for any kind of help or information regarding this topic.

I did watch WWDC 2019 Session 716 and understand that an active audio session is key to unlocking low‑level networking on watchOS. I’m configuring my audio session and engine as follows: private func configureAudioSession(completion: @escaping (Bool) -> Void) { let audioSession = AVAudioSession.sharedInstance() do { try audioSession.setCategory(.playAndRecord, mode: .voiceChat, options: []) try audioSession.setActive(true, options: .notifyOthersOnDeactivation) // Retrieve sample rate and configure the audio format. let sampleRate = audioSession.sampleRate print("Active hardware sample rate: \(sampleRate)") audioFormat = AVAudioFormat(standardFormatWithSampleRate: sampleRate, channels: 1) // Configure the audio engine. audioInputNode = audioEngine.inputNode audioEngine.attach(audioPlayerNode) audioEngine.connect(audioPlayerNode, to: audioEngine.mainMixerNode, format: audioFormat) try audioEngine.start() completion(true) } catch { print("Error configuring audio session: \(error.localizedDescription)") completion(false) } } private func setupUDPConnection() { let parameters = NWParameters.udp parameters.includePeerToPeer = true connection = NWConnection(host: "***.***.xxxxx.***", port: 0000, using: parameters) setupNWConnectionHandlers() } private func setupTCPConnection() { let parameters = NWParameters.tcp connection = NWConnection(host: "***.***.xxxxx.***", port: 0000, using: parameters) setupNWConnectionHandlers() } private func setupWebSocketConnection() { guard let url = URL(string: "ws://***.***.xxxxx.***:0000") else { print("Invalid WebSocket URL") return } let session = URLSession(configuration: .default) webSocketTask = session.webSocketTask(with: url) webSocketTask?.resume() print("WebSocket connection initiated") sendAudioToServer() receiveDataFromServer() sendWebSocketPing(after: 0.6) } private func setupNWConnectionHandlers() { connection?.stateUpdateHandler = { [weak self] state in DispatchQueue.main.async { switch state { case .ready: print("Connected (NWConnection)") self?.isConnected = true self?.failToConnect = false self?.receiveDataFromServer() self?.sendAudioToServer() case .waiting(let error), .failed(let error): print("Connection error: \(error.localizedDescription)") DispatchQueue.main.asyncAfter(deadline: .now() + 2) { self?.setupNetwork() } case .cancelled: print("NWConnection cancelled") self?.isConnected = false default: break } } } connection?.start(queue: .main) } I am reaching out to seek further assistance regarding the challenges I've been experiencing with establishing a UDP, TCP & web socket connection on watchOS using NWConnection for duplex audio streaming. Despite implementing the recommendations provided earlier, I am still encountering difficulties. Or duplex audio streaming not possible on apple watch?

We’re building a new subway/bus app at the MTA. Our system includes roughly 300 underground stations, around 150 elevated stations (i.e., above street level), and about 5 at-grade stations (i.e., at street level). We serve roughly 5 million riders a day. We’re diving deep into Core Location on iOS and have found that the altitude values returned from two fields we’re testing aren’t accurate enough for our use case: CLLocation.altitude CMAbsoluteAltitudeData.altitude We need to reliably distinguish whether a user is: At street level On an elevated platform (see attached picture) On any platform in an underground station — most have a single platform level, but some, like 59 St (see attached), have multiple platforms at different elevations. These levels typically differ by at least 15 feet, which should in theory be well within the precision range of a properly calibrated barometric pressure sensor. However, the absolute altitude values we’re seeing from these APIs are often inaccurate and inconsistent — not only compared to ground truth, but also across devices. For example, holding two phones side-by-side frequently yields altitude readings that differ by more than 15 feet. That level of variation makes the data unreliable for our needs.

I have multiple app ids that are registered with Push Notification, however they do not hsow up in the Push Notification Console for testing.

My laptop (M1 Pro, macOS 15.3.2) is connected to a dual stack network via Wi-Fi. The home.arpa. domain is supplied as a search domain via both DHCPv4 (options 15 and 119) and DHCPv6 (option 24). "Details…" for the network connection in System Settings show this domain under the DNS tab. The laptop uses a Forwarding DNS Resolver of my router, which in turn forwards requests for home.arpa. (including subdomains) to a local DNS server (CoreDNS) which is authoritative for this zone.

Hi, i'm unable to select a icc profile on the new macbook Pro M4. How can i calibrate the internal screen by adding an icc profil made with my X-Rite color calibrator. icc files cannot be selected (grey) from the import menu of the monitor preferences.

I'm working on implementing file moving with NSFileCoordinator. I'm using the slightly newer asynchronous API with the NSFileAccessIntents. My question is, how do I go about notifying the coordinator about the item move? Should I simply create a new instance in the asynchronous block? Or does it need to be the same coordinator instance? let writeQueue = OperationQueue() public func saveAndMove(data: String, to newURL: URL) { let oldURL = presentedItemURL! let sourceIntent = NSFileAccessIntent.writingIntent(with: oldURL, options: .forMoving) let destinationIntent = NSFileAccessIntent.writingIntent(with: newURL, options: .forReplacing) let coordinator = NSFileCoordinator() coordinator.coordinate(with: [sourceIntent, destinationIntent], queue: writeQueue) { error in if let error { return } do { // ERROR: Can't access NSFileCoordinator because it is not Sendable (Swift 6) coordinator.item(at: oldURL, willMoveTo: newURL) try FileManager.default.moveItem(at: oldURL, to: newURL) coordinator.item(at: oldURL, didMoveTo: newURL) } catch { print("Failed to move to \(newURL)") } } }

This question has been asked several times by other users before. But there is no solution provided it seems. So I am asking the same here. I have a screen where I add mapview as a subview. In that it is showing instead of "Legal".

I'm a first time developer for Swift, (getting on a bit!) but after programming in VB back in the late 90s I wanted to write an app for iPhone. I think I might have gone about it the wrong way, but I've got an app that works great on my iPhone or works great on my iPad. It saves the data persistently on device, but, no matter how much I try, what I read and even resorting to AI (ChatGPT & Gemini) I still can't get it to save the data on iCloud to synchronise between the two and work across the devices. I think it must be something pretty fundamental I'm doing (or more likely not doing) that is causing the issue. I'm setting up my signing and capabilities as per the available instructions but I always get a fatal error. I think it might be something to do with making fields optional, but at this point I'm second guessing myself and feeling a complete failure. Any advice or pointers would be really gratefully appreciated. I like my app and would like eventually to get it on the App Store but at this point in time I feel it should be on the failed projects heap! I've even tried a new Xcode project for iOS and asking it to use SwiftData and CloudKit - the default project should work - right? But it absolutely doesn't for me. Please send help!!

Is there any way to find the reason for a CRASHING_DUE_TO_PRIVACY_VIOLATION from a crash report? It does not happen on my old iPad Air 2 and it does not happen on the simulators with the latest iOS. But it crashes always on newer real devices to which I have no access. The last app review for the AppStore also did not find it. I added some privacy strings by guessing and sent it via TestFlight but it doesn't change anything.

I'm trying to invoke a 3rd party command line tool from a launch agent to connect to a server on my LAN. It seems impossible. I have a little shell script that does what I need, and it works fine invoked in Terminal.app. The first time I run it that way I get permission prompts and I agree to them all. Subsequent invocations work. Now I put a launch agent in ~/Library/Launch Agents. It does nothing more than invoke my shell script at some specific time daily. launchd launches it, but it fails to access the LAN, with a 'no route to host' error message. The command line tool I'm trying to use is not a macOS-provided one, but one from MacPorts/HomeBrew (I tried both). It doesn't even matter which tool I'm using, I tried a very simple case of just using nc/netcat. If I use the macOS-provided nc, then I can access my LAN. If I install nc from MacPorts /HomeBrew, that nc cannot access my LAN. This I've reproed on a literally brand new Mac, then updated to newest Sequoia (15.3.2), then done all I've described above. I've ruled out DNS by working with raw IP addresses. I've disabled gatekeeper with sudo spctl --master-disable. I've tried using cron instead of launch agents, same results. I've tried codesigning with codesign -dvvv /opt/homebrew/bin/nc, no help. I've read TN3179 Understanding local network privacy. In summary: Terminal.app -> script -> macOS/brew nc -> internet/LAN = works launchagent -> script -> macOS nc -> internet = works launchagent -> script -> macOS nc -> LAN = works launchagent -> script -> brew nc -> internet = works launchagent -> script -> brew nc -> LAN = fails How can I make that last case work?

Does someone know how to debug ios app on mac designed for iPad? i can debug on real iOS device but cant attach Tunnel to work for mac.

Hello, I hope to find out more about how AppTransaction works on macOS, specifically about its internet connection requirements: if I use this to validate that the app is a legit purchase from the Mac App Store, I would not want it to have an always-on requirement just to validate. Does AppTransaction require the user to always be online for AppTransaction.shared ? When an app is downloaded from the Mac App Store, is the data needed for AppTransaction automatically embedded during that download, or is that data downloaded upon first launch of the app, therefore requiring an internet connection at launch time? Once the data/receipt has been downloaded by AppTransaction, is it cached until the app's next update, or is it cleared at some time during the version's life and needs to be re-downloaded, therefore requiring an internet connection at launch? Where is that receipt/data stored? Also, if you don't mind me sneaking in this non-related but sort of related question, in terms of receipt validation: Does macOS Sequoia's MAC address rotation feature affect receipt validation in any way when using IOKit? Thank you kindly, – Matthias

I'm using Swift to verify receipts in myObjective C Mac Application using the following code: @objc class MyAppTransaction: NSObject{ @objc class func checkReceipt() async -> String { do { let verificationResult = try await AppTransaction.shared switch verificationResult { case .verified(_): return "VERIFIED" case .unverified(_, _): return "NO RECEIPT" } } catch { return "ERROR" //(StoreKit.StoreKitError) unknown } } } Starting today with my upgrade to Sequoia 15.4 and XCode 16.3 receipt validation is broken. The function is going to the catch and returning "ERROR" I can't set a break point in the do {} but if I set one at the return "ERROR", in the debugger error = (StoreKit.StoreKitError) unknown. the Compiler logs an error:Failed to parse AppTransaction: missingValue(for: [StoreKit.AppTransaction.Key.appTransactionID], expected: StoreKit.BackingValue). Reading the developer documentation I can't find anything about these struct members. I tried to use refresh() to get a receipt like I used to with exit(173) but the compiler says refresh () not found. This is extremely troubling because I can't debug my receipt validation code and I don't know if this will happen to my users. Do I just have to trust Apple that my users will have an application with a receipt attached? What can I do?
