Hello, I want to use universal links in my application, for which I need to get the TeamID and BundleId, for apple-app-site-association file. Can you please tell me, do I have to buy an Apple Developer Account at the time of development to do this, or can I get it all for free at the time of development?

Hi, We are facing a major issue with our application. We are using FolioReaderkit to read epub files. Currently, it's working on the iOS 18.1 device and simulator, but it's not working on the iOS 18.2 and later version devices. we are facing this error in Folioreaderkit

Hello, I uploaded a new iOS build (1.0.1 - Build 180) to App Store Connect for my app "Benimle Konus". The build has been processed successfully and is marked as "Ready to Test". However, when I try to assign this build to any internal TestFlight group, the group checkboxes are greyed out and cannot be selected. I’ve made sure that: All required metadata is filled out. What’s New and compliance information is complete. Previous builds worked with the same TestFlight groups. To fix this, I have uploaded 3 separate builds, but the issue still persists with all of them. There are no error messages, but I can't continue testing because I can't assign the build to testers. App ID: 6742759002 Bundle ID: com.benimlekonus.app Build Version: 1.0.1 (180) Is this a known issue or something I'm missing? Any help would be appreciated.

Hello, aspiring programmer here. I am developing a StepCounter APP, which keeps track of how many steps I have taken and sends to an MQTT server. I am trying to make this happen even while the app is not in focus, but so far I have not been able to get this working. First tried with silent background music, which seemed pretty inconsistent and inpractical, since I usually play youtube videoes while walking, making the app stop with its silent audio. Then tried GPS, which didnt really do anything (could be implementation problem). Has anyone made background processing work for their apps?

I am trying to open items saved to my files and keep receiving this notification every time I do so, “The operation couldn't be completed. (NSFileProvider- ErrorDomain error -2005.)” What does this mean and how do I fix it? I have a 256 gb phone so I know storage is not an issue. Please help as I have files saved to my phone and not anywhere else.

I ran into a problem. When using Storekit1 to purchase an SKU, the user payment was successful, but StoreKit1 did return paymentCancelled to my App. I would like to know under what circumstances this problem may occur? How do I fix it? Thank you

Hello, I have to create an app in Swift that it scan NFC Identity card. It extract data and convert it to human readable data. I do it with below code import CoreNFC class NFCIdentityCardReader: NSObject , NFCTagReaderSessionDelegate { func tagReaderSessionDidBecomeActive(_ session: NFCTagReaderSession) { print("\(session.description)") } func tagReaderSession(_ session: NFCTagReaderSession, didInvalidateWithError error: any Error) { print("NFC Error: \(error.localizedDescription)") } var session: NFCTagReaderSession? func beginScanning() { guard NFCTagReaderSession.readingAvailable else { print("NFC is not supported on this device") return } session = NFCTagReaderSession(pollingOption: .iso14443, delegate: self, queue: nil) session?.alertMessage = "Hold your NFC identity card near the device." session?.begin() } func tagReaderSession(_ session: NFCTagReaderSession, didDetect tags: [NFCTag]) { guard let tag = tags.first else { session.invalidate(errorMessage: "No tag detected") return } session.connect(to: tag) { (error) in if let error = error { session.invalidate(errorMessage: "Connection error: \(error.localizedDescription)") return } switch tag { case .miFare(let miFareTag): self.readMiFareTag(miFareTag, session: session) case .iso7816(let iso7816Tag): self.readISO7816Tag(iso7816Tag, session: session) case .iso15693, .feliCa: session.invalidate(errorMessage: "Unsupported tag type") @unknown default: session.invalidate(errorMessage: "Unknown tag type") } } } private func readMiFareTag(_ tag: NFCMiFareTag, session: NFCTagReaderSession) { // Read from MiFare card, assuming it's formatted as an identity card let command: [UInt8] = [0x30, 0x04] // Example: Read command for block 4 let requestData = Data(command) tag.sendMiFareCommand(commandPacket: requestData) { (response, error) in if let error = error { session.invalidate(errorMessage: "Error reading MiFare: \(error.localizedDescription)") return } let readableData = String(data: response, encoding: .utf8) ?? response.map { String(format: "%02X", $0) }.joined() session.alertMessage = "ID Card Data: \(readableData)" session.invalidate() } } private func readISO7816Tag(_ tag: NFCISO7816Tag, session: NFCTagReaderSession) { let selectAppCommand = NFCISO7816APDU(instructionClass: 0x00, instructionCode: 0xA4, p1Parameter: 0x04, p2Parameter: 0x00, data: Data([0xA0, 0x00, 0x00, 0x02, 0x47, 0x10, 0x01]), expectedResponseLength: -1) tag.sendCommand(apdu: selectAppCommand) { (response, sw1, sw2, error) in if let error = error { session.invalidate(errorMessage: "Error reading ISO7816: \(error.localizedDescription)") return } let readableData = response.map { String(format: "%02X", $0) }.joined() session.alertMessage = "ID Card Data: \(readableData)" session.invalidate() } } } But I got null. I think that these data are encrypted. How can I convert them to readable data without MRZ, is it possible ? I need to get personal informations from Identity card via Core NFC. Thanks in advance. Best regards

Hi everyone, I’m trying to detect if Developer Mode is enabled on iOS 16+ devices using Swift but haven’t found any official APIs or documentation for this. Are there Apple-recommended ways to achieve this, or is it restricted for privacy/security reasons? Thanks!

since updating from 18.3 to 18.4, both on cellular and WiFi Networks I can’t connect to the internet. Since the phone wont connect to the internet I’m not able to turn off “find my iPhone“ to restore my iPhone to iOS 18.3 this way my iPhone is useless any ideas / thoughts about this?

I just started working with Flutter. I use a Macbook m2 and my phone is an iPhone XR. I made a very simple application but no matter what I did, I couldn't start my application on my iPhone XR. I got help from all the AIs but we couldn't do it. I deleted everything including Xcode, Android Studio and Flutter and reinstalled them and I followed the SDK installation step by step on the Flutter page but I can't run my project on Xcode. I entered my Apple account including all the signings and certificates via the .workspace file extension but it didn't work. The error I get from Xcode keeps changing. We installed podfiles with the support I got from the AIs and after some fiddling, I got the only error right now: Command PhaseScriptExecution failed with a nonzero exit code

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.

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.

My iPhone 11 has iOS 18.4 Beta and my new iPhone 16e isn’t supported for iOS 18.4 Beta (for now) and is on iOS 18.3.1 Beta. If anyone knows when it’ll be supported please let me know.

I have an iPhone app which relies heavily on TCP/IP communication in the local network. Therefore, the application starts a server socket and accepts incoming connections. This worked flawlessly for a long time and we had no problems with this. Problem In the last days however, we observed that for some iPhones with the server role other devices cannot connect to the server of our app. The server does not accept incoming connections on the devices IP address and the client times out. Environment Both iPhones (the server and the client) are in the same network with 192.168.1.0 address range and 255.255.255.0 subnet mask. The server has the IP 192.168.1.11 and the client has 192.168.1.22. This is a normal home WiFi network with no special firewall rules. Both devices have mobile data disabled and the "access local network" permission is granted. The server socket is bound to all interfaces (0.0.0.0). More technical symptoms When the server iPhone is in this faulty state, it seems like it somehow has two ip addresses: 192.168.2.123 and 192.168.1.11 The WiFi preferences show the (correct) .1.11 ip address. The Apps however see the (wrong) .2.123 ip address. I cannot explain where the other ip address comes from and why the device thinks it has this ip address. I've collected interface diagnosis information on a faulty iPhone and it listed the following interfaces and IPs: en0 -> 192.168.2.123 lo0 -> 127.0.0.1 pdp_ip0 (cellular) -> 192.0.0.2 pdp_ip1 to pdp_ip6 (cellular) -> -/- ipsec0 to ipsec6 (vpn) -> -/- llw0 (vpn) -> -/- awdl0 -> -/- anpi0 -> -/- ap1 -> -/- XHC0 -> -/- en1 and en2 (wired) -> -/- utun0 to utun2 (vpn) -> -/- The correct ip of the device is not listed anywhere in this list. A reboot helped to temporarily fix this problem. One user reported the same issue again a few hours later after a reboot. Switching off WiFi and reconnecting does not solve the problem. This issue occurred on several iPhones with the following specs: iOS Version 18.1.1, 18.3.1 iPhone 13 Pro, iPhone 13 Pro Max, iPhone 15 Pro The problem must be on the server side as the client can successfully connect to any other device in the same network. Question(s) Where does this second IP come from and why does the server not accept connections to either ip even though it is bound to 0.0.0.0? Are there any iOS system settings which could lead to this problem? (privacy setting, vpn, ...) What could be done to permanently fix this issue?

Hi, Currently I am developing a 3D reconstruction project. Which requires images to be distortion-free (rectilinear) and with known intrinsics. The session I am developing on is a builtInDualWideCamera, with isGeometricDistortionCorrectionEnabled set to false to be able to get the intrinsic matrix of the images, isVirtualDeviceConstituentPhotoDeliveryEnabled set to true and isAutoVirtualDeviceFusionEnabled set to false to get both images and isCameraCalibrationDataDeliveryEnabled set to true to actually get the calibration data. The distortion correction parameters such as lensDistortionLookupTable are used. The 42 coefficients mapping array is used as described in the AVCameraCalibrationData header file. A simple piecewise linear interpolation. There are two questions I would like to get support on: A way to set the calibration parameters in each image. I have an approach that sets the parameters in the kCGImagePropertyExifDictionary -> "UserComment". Is there a better approach to write calibration parameter data into the images? I feel like this is a bit dirty and there might be a better and neat approach. For the ultra-wide angle camera's images, the lensDistortionLookupTable contains several zeros at the end of the array. For example (last 10 elements are zero): "LensDistortionLookupTable":"0.000000000000000,0.000349554029526,0.001385628827848,0.003071037586778,... ,0.000000000000000,0.000000000000000,0.000000000000000,0.000000000000000,0.000000000000000,0.000000000000000,0.000000000000000,0.000000000000000,0.000000000000000,0.000000000000000" The problem comes when the complete array is used to correct the image (including zeros), the end result is a wrapped-like-circle image close to the edges of it which is completely wrong. In contrast, if the LensDistortionLookupTable is used without the last zeros and the new size accommodated the image looks better (although not as rectilinear as if you take the image from the iPhone's camera app), but definitely less distorted. Including zeros (full array): Excluding zeros (array size changed): Am I missing an important point in the usage of the lensDistortionLookupTable where this case is addressed (zeros at the end)? What is the criteria to shrink/exclude elements of the array? Any advice is very much welcome.

I've been running into an issue using .fileImporter in SwiftUI already for a year. On iPhone simulator, Mac Catalyst and real iPad it works as expected, but when it comes to the test on a real iPhone, the picker just won't let you select files. It's not the permission issue, the sheet won't close at all and the callback isn't called. At the same time, if you use UIKits DocumentPickerViewController, everything starts working as expected, on Mac Catalyst/Simulator/iPad as well as on a real iPhone. Steps to reproduce: Create a new Xcode project using SwiftUI. Paste following code: import SwiftUI struct ContentView: View { @State var sShowing = false @State var uShowing = false @State var showAlert = false @State var alertText = "" var body: some View { VStack { VStack { Button("Test SWIFTUI") { sShowing = true } } .fileImporter(isPresented: $sShowing, allowedContentTypes: [.item]) {result in alertText = String(describing: result) showAlert = true } VStack { Button("Test UIKIT") { uShowing = true } } .sheet(isPresented: $uShowing) { DocumentPicker(contentTypes: [.item]) {url in alertText = String(describing: url) showAlert = true } } .padding(.top, 50) } .padding() .alert(isPresented: $showAlert) { Alert(title: Text("Result"), message: Text(alertText)) } } } DocumentPicker.swift: import SwiftUI import UniformTypeIdentifiers struct DocumentPicker: UIViewControllerRepresentable { let contentTypes: [UTType] let onPicked: (URL) -> Void func makeCoordinator() -> Coordinator { Coordinator(self) } func makeUIViewController(context: Context) -> UIDocumentPickerViewController { let documentPicker = UIDocumentPickerViewController(forOpeningContentTypes: contentTypes, asCopy: true) documentPicker.delegate = context.coordinator documentPicker.modalPresentationStyle = .formSheet return documentPicker } func updateUIViewController(_ uiViewController: UIDocumentPickerViewController, context: Context) {} class Coordinator: NSObject, UIDocumentPickerDelegate { var parent: DocumentPicker init(_ parent: DocumentPicker) { self.parent = parent } func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentsAt urls: [URL]) { print("Success!", urls) guard let url = urls.first else { return } parent.onPicked(url) } func documentPickerWasCancelled(_ controller: UIDocumentPickerViewController) { print("Picker was cancelled") } } } Run the project on Mac Catalyst to confirm it working. Try it out on a real iPhone. For some reason, I can't attach a video, so I can only show a screenshot

The charging port of my iPhone may be damaged due to water, and it cannot be charged and transmitted data. It can only be charged wirelessly that does not support data transmission. However, since Xcode supports wireless debugging, I can continue to test my App. However, I recently changed to a new Mac, but there is no connection record with the iPhone in the new Mac, which makes it impossible to debug wirelessly. So I want to know how to realize wireless debugging on such a device without debugging records?

Hello, After deploying our app, we encountered an issue where the app fails to launch properly on certain devices. To rule out potential code issues, we created a new clean project and tested it with the basic setup (certificate, bundle ID, and team). The app installs and runs fine on most devices, but it fails to open immediately on specific models. (The affected model is listed below.) Version: iOS 18.3.1 Model: iPhone 14 Pro After reviewing the console logs, we found an issue related to the app launching process. Could this issue be related to the app's configuration or the provisioning profile? We would appreciate any insight into why this issue occurs only on certain devices. Thank you for your help!
