iOS 18 breaks IMAP Mail retrieval for some users
Posting here for wider visibility... All over the internet, apple discussions, etc. Seems that this is affecting thousands of people but apparently not millions...othewise we'd have a fix by now. This started showing up in iOS 18 beta and then continued into 18.0, 18.1, and now 18.2 Symptoms are unable to retrieve emails from IMAP mail server. Some have mentioned Dovecot IMAP server. This author happens to have Dovecot IMAP and yes, once iOS 18.0, 18.x was installed, email sync no longer works.

iOS sdcard plug-in/unplug event and read problems
Currently, we use UIDocumentPickerViewController to read the user's connected sdcard. However, this requires the user to select manually, and the event cannot be monitored. But recently I found that ImageCaptureCore's ICDeviceBrowserDelegate can monitor the plug-in and unplug events in the didAddDevice callback, but cannot obtain the path of the storage card. I wonder if there is a way to combine the advantages of both, so that with the user's consent, the card reader events can be monitored and the content can be read directly without the user manually selecting the folder

Join Wi-Fi Network from QR Code
I was wondering if anybody knows if it's possible for an app to use a QR code to join a Wi-Fi network - the same functionality as the iOS 11 Camera app?I have some code reading a QR Code that looks something like - "WIFI:S:name-of-network;T:WPA;P:password;;"This QR code works perfectly in the native camera app - asking the user if they'd like to join the Wi-Fi network and successfully joining if they do.When I scan the QR code in my own code, I get the following error: canOpenURL: failed for URL: "WIFI:S:name-of-network;T:WPA;P:password;;" - error: "The operation couldn’t be completed. (OSStatus error -10814.)"In my app, I've got URL Schemes for "prefs" and have added "wifi" in LSApplicationQueriesSchemes.Am I doing something wrong, or is this simply not possible?If it's not possible, is there anyway to use the iOS native camera functionality within an app?

How to reset Local Network Privacy settings?
On macOS 15, if a program installed in /Applications is allowed to connect to a PostgreSQL server on another machine on the local network, a program launched in debug mode from Xcode is not allowed to connect to the local network, and no prompt appears. Although it is possible to turn off registered programs in Local Network Privacy in Beta 2, permissions for programs launched from Xcode cannot be obtained at all. Does anyone know how to solve this problem?

First update to NWBrowser is always ready, irrespective of Local Networking privacy status
I'm trying to detect the state of Local Network privacy on macOS Sequoia via NWBrowser, as recommended in https://developer.apple.com/documentation/technotes/tn3179-understanding-local-network-privacy Regardless of the state of Local Network privacy - undetermined, allowed or denied, NWBrowser receives an update indicating that its in the ready state. Scanning does not seem to trigger the Local Network privacy alert for me - I have to use the other recommended method to trigger the prompt. Enabling or disabling Local Network privacy does not seem to send any updates for NWBrowser. https://developer.apple.com/forums/thread/666431 seems related, and implies that they did receive further updates to NWBrowser.

System Network Extension and Sleep
I've implemented a custom VPN for macOS (system extension, Packet Tunnel Provider, Developer ID). My tunneling logic uses BSD sockets. My VPN is configured with on-demand and should always connect when there's traffic: targetManager?.isOnDemandEnabled = true targetManager?.onDemandRules = [NEOnDemandRuleConnect()] I have encountered some issues when the device enters sleep (or waking up from sleep). I've tried two scenarios. Scenario 1: protocolConfiguration?.disconnectOnSleep = true With this flag set, the OS will disconnect the VPN just before entering to sleep. However, there were cases when the OS disconnected the VPN but immediately restarted it - probably because of how I defined the on-demand rules. This resulted in the VPN disconnection, then trying to reconnect, and then the Mac entered sleep. When the Mac woke up, the VPN didn't work well. Is there a way to avoid waking up, just before the Mac enters sleep? Scenario 2: protocolConfiguration?.disconnectOnSleep = false Disconnect on sleep is unset, and I've implemented the sleep/wake functions at the provider. With this configuration, the OS won't disconnect the VPN, so even in sleep, the extension should stay 'alive,' so it won't have the problem from (1). But in this case, I had other problems: On sleep, I'm disconnecting the tunnel. But sometimes, on wake(), all my network calls fail. Are the interfaces still down? How can I detect this case from the system extension? Is it possible that the OS would call sleep and then quickly call wake? Is it possible that after sleep, the OS would call the startTunnelWithOptions() function? Is it possible to restart the extension from a clean state right from the wake() function?

How to Archive iMessages via API with User Authorization Workflow?
I’m working on a solution to archive iMessages by using an API or similar mechanism. Here’s the desired workflow: The user provides their phone number to initiate the archiving process. They receive a text message with a URL link. Clicking on the link authorizes the archiving of their iMessages. Once authorized, their text messages are archived. So far, I’ve researched third-party services and APIs but haven’t found any that offer this capability directly for iMessages. Questions: Are there any APIs or frameworks (Apple or third-party) that support accessing and archiving iMessages programmatically?

Not able to log proc ID in controlFilter
I was trying to log the flow description using control filter and data filter. But when I am trying to log the proc ID in control filter, it is always 0, but in data filter, it logs some value. Same goes with the eproc ID. I want to use the flow description data in some other target so I will be sending the data using sockets and I cannot share data from data filter due to its restrictions and control filter isn't providing the proc ID. What should I do?

NESMVPNSession disconnected
Hi, I have a problem with my OpenVPN connection on my app with iOS 14.4.

WatchConnectivity Swift 6 - Incorrect actor executor assumption
I am trying to migrate a WatchConnectivity App to Swift6 and I found an Issue with my replyHandler callback for sendMessageData. I am wrapping sendMessageData in withCheckedThrowingContinuation, so that I can await the response of the reply. I then update a Main Actor ObservableObject that keeps track of the count of connections that have not replied yet, before returning the data using continuation.resume. ... @preconcurrency import WatchConnectivity actor ConnectivityManager: NSObject, WCSessionDelegate { private var session: WCSession = .default private let connectivityMetaInfoManager: ConnectivityMetaInfoManager ... private func sendMessageData(_ data: Data) async throws -> Data? { Logger.shared.debug("called on Thread \(Thread.current)") await connectivityMetaInfoManager.increaseOpenSendConnectionsCount() return try await withCheckedThrowingContinuation({ continuation in self.session.sendMessageData( data, replyHandler: { data in Task { await self.connectivityMetaInfoManager .decreaseOpenSendConnectionsCount() } continuation.resume(returning: data) }, errorHandler: { (error) in Task { await self.connectivityMetaInfoManager .decreaseOpenSendConnectionsCount() } continuation.resume(throwing: error) } ) }) } Calling sendMessageData somehow causing the app to crash and display the debug message: Incorrect actor executor assumption. The code runs on swift 5 with SWIFT_STRICT_CONCURRENCY = complete. However when I switch to swift 6 the code crashes. I rebuilt a simple version of the App. Adding bit by bit until I was able to cause the crash. See Broken App Awaiting sendMessageData and wrapping it in a task and adding the @Sendable attribute to continuation, solve the crash. See Fixed App But I do not understand why yet. Is this intended behaviour? Should the compiler warn you about this? Is it a WatchConnectivity issue? I initially posted on forums.swift.org, but was told to repost here.

New apple pay in PC chrome dosn't work with iOS 18
I've encountered an issue with Apple Pay in PC Chrome with iOS 18. Below is the scenario and code for reference: Issue Scenario: A button is clicked to initiate the Apple Pay process. A QR code window pops up, which I scan with my phone. As soon as the session is established, the window closes immediately, not allowing the user to select a payment card. No errors appear in the console. Here's the code snippet for handling the Apple Pay button click: const onApplePayButtonClicked = () => { if (!window.ApplePaySession) { return; } log('Apple Pay button clicked'); const request = { countryCode: 'UA', currencyCode: 'UAH', merchantCapabilities: ['supports3DS'], supportedNetworks: ['visa', 'masterCard'], total: { label: 'PoC Merchant Apple Pay', type: 'final', amount: amount.toString(), }, }; const session = new window.ApplePaySession(3, request); session.onvalidatemerchant = async (event) => { try { log('Creating ApplePaySession'); const response = await fetchAppleSessionAPI(event.validationURL, applePayMercantId, { deviceId, refreshToken }); log('validateMerchantResponse', response); session.completeMerchantValidation(response.applePaySessionData); } catch (error) { log('validateMerchantError', error); } }; session.onshippingmethodselected = () => { const newTotal = { label: 'PoC Merchant Apple Pay', type: 'final', amount: amount.toString(), }; session.completeShippingMethodSelection(window.ApplePaySession.STATUS_SUCCESS, {}, newTotal); }; session.onpaymentauthorized = async (event) => { log('onpaymentauthorized', event); const result = { status: window.ApplePaySession.STATUS_SUCCESS, }; session.completePayment(result); log('TOKEN', event.payment.token); }; session.begin(); }; Troubleshooting Steps Taken: Verified that window.ApplePaySession is available. Checked for any console errors—none found. Confirmed that the QR code scanning and session initiation work as expected. Expected Behavior: After scanning the QR code and establishing the session, the user should be able to select a payment card and proceed with the payment flow. Current Behavior: The window closes immediately after the session is established, preventing card selection. Has anyone else faced this issue or has insights on how to resolve it? Thanks in advance!

Unable to detect changes to language from Settings post a initial manual override
We have a requirement in the App in which for certain countries/regions we have to support only certain languages. If the User's current language is not supported, We would have a custom fallback/default language for specific regions. like it could be Arabic for middle east countries, English for Europe etc. Since iOS localization allows fallback to only one Base localizations, we had to take a custom approach to implement the same. To achieve the same, we checked the User's current language and Country and if required we overrode the "kLanguageBundleKey" property within the Bundle class, and set the following user defaults, (here for example say english) Foundation.UserDefaults.standard.set(["en"], forKey: "AppleLanguages") Foundation.UserDefaults.standard.synchronize(). And it works! The problem is that in iOS, post this override, when the user changes language from the Phone's settings app. Launches our app, Bundle.main.preferredLocalizations.first always gives what we overwrote and not the one present in the Phone's settings. Given this, Is there way to get the user's current language even after such overrides? or should we do the language overrides some other way?

Detecting Driving State with Core Motion Framework - Automotive Accuracy Issues
I am working on an iOS app where I need to detect when a user starts and stops driving using the Apple Core Motion framework. I've implemented the following MotionActivityManager class to handle activity updates and display the detected states in a SwiftUI view. While I can accurately detect "Stationary" and "Walking" states, detecting the "Driving" (Automotive) state has been unreliable. The accuracy often fails, and the framework frequently misclassifies driving as other states like "Unknown" or "Walking." Here's the implementation: @Published var motionStates: [MotionState] = [] @Published var startDate: String = "" @Published var confidence: String = "" init() { setupDefaultStates() startActivityUpdates() } private func setupDefaultStates() { motionStates = [ MotionState(label: "Stationary", value: false), MotionState(label: "Walking", value: false), MotionState(label: "Running", value: false), MotionState(label: "Automotive", value: false), MotionState(label: "Cycling", value: false), MotionState(label: "Unknown", value: false) ] } func startActivityUpdates() { guard CMMotionActivityManager.isActivityAvailable() else { print("Motion activity is not available.") return } motionActivityManager.startActivityUpdates(to: .main) { [weak self] motion in guard let self = self, let motion = motion else { return } DispatchQueue.main.async { self.updateProperties(with: motion) } } } private func updateProperties(with motion: CMMotionActivity) { motionStates = [ MotionState(label: "Stationary", value: motion.stationary), MotionState(label: "Walking", value: motion.walking), MotionState(label: "Running", value: motion.running), MotionState(label: "Automotive", value: motion.automotive), MotionState(label: "Cycling", value: motion.cycling), MotionState(label: "Unknown", value: motion.unknown) ] startDate = dateFormatter.string(from: motion.startDate) switch motion.confidence { case .low: confidence = "Low" case .medium: confidence = "Medium" case .high: confidence = "High" @unknown default: confidence = "Unknown" } } } struct MotionState: Identifiable { let id = UUID() let label: String let value: Bool } struct ContentView: View { @StateObject private var motionManager = MotionActivityManager() var body: some View { ScrollView { VStack(spacing: 16) { ForEach(motionManager.motionStates) { state in LabelView(label: state.label, value: state.value ? "True" : "False") } LabelView(label: "Confidence", value: motionManager.confidence) } .padding() } .onAppear { UIApplication.shared.isIdleTimerDisabled = true motionManager.startActivityUpdates() } .navigationTitle("Motion Activity") } } Issues: The motion.automotive state is often not detected accurately. The confidence level remains low for the automotive state, even when the device is clearly in a car. How can I improve the detection accuracy of the "Driving" state using the Core Motion framework?

Disable SwiftData CloudKit sync when iCloud account is unavailable
I have a widely-used app that lets users keep track of personal data. This data is persisted with SwiftData, and synced with CloudKit. I understand that if the user's iCloud account changes on a device (for example, user logs out or toggles off an app's access to iCloud), then NSPersistentCloudKitContainer will erase the local data records on app launch. This is intentional behavior, intended as a privacy feature. However, we are receiving regular reports from users for whom the system has incorrectly indicated that the app's access to iCloud is unavailable, even when the user hasn't logged out or toggled off permission to access iCloud. This triggers the behavior to clear the local records, and even though the data is still available in iCloud, to the user, it looks like their data has disappeared for no reason. Helping the user find and troubleshoot their iCloud app data settings can be very difficult, since in many cases the user has no idea what iCloud is, and we can't link them directly to the correct settings screen. We seem to get these reports most frequently from users whose iCloud storage is full (which feels like punishment for not paying for additional storage), but we've also received reports from users who have enough storage space available (and are logged in and have the app's iCloud data permissions toggled on). It appears to happen randomly, as far as we can tell. I found a blog post from two years ago from another app developer who encountered the same issue: https://crunchybagel.com/nspersistentcloudkitcontainer/#:~:text=The%20problem%20we%20were%20experiencing To work around this and improve the user experience, we want to use CKContainer.accountStatus to check if the user has an available iCloud account, and if not, disable the CloudKit sync before it erases the local data. I've found steps to accomplish this workaround using CoreData, but I'm not sure how to best modify the ModelContainer's configuration after receiving the CKAccountStatus when using SwiftData. I've put together this approach so far; is this the right way to handle disabling/enabling sync based on account status? import SwiftUI import SwiftData import CloudKit @main struct AccountStatusTestApp: App { @State private var modelContainer: ModelContainer? var body: some Scene { WindowGroup { if let modelContainer { ContentView() .modelContainer(modelContainer) } else { ProgressView("Loading...") .task { await initializeModelContainer() } } } } func initializeModelContainer() async { let schema = Schema([ Item.self, ]) do { let accountStatus = try await CKContainer.default().accountStatus() let modelConfiguration = ModelConfiguration( schema: schema, cloudKitDatabase: accountStatus == .available ? .private("iCloud.com.AccountStatusTestApp") : .none ) do { let container = try ModelContainer(for: schema, configurations: [modelConfiguration]) modelContainer = container } catch { print("Could not create ModelContainer: \(error)") } } catch { print("Could not determine iCloud account status: \(error)") } } } I understand that bypassing the clearing of local data when the iCloud account is "unavailable" introduces possible issues with data being mingled on shared devices, but I plan to mitigate that with warning messages when users are in this state. This would be a far more preferable user experience than what's happening now.
