Hi everyone, I'm building a task management app that layers on top of EventKit/Reminders. I'm also moderating /r/AppleReminders. I see a confusion around the semantics of dates on both the developer side and on the user side. I'm trying to map the standard productivity mental model to the EKReminder implementation and hitting some walls. In productivity contexts, a task tends to have three distinct dates: Start Date: When the task becomes actionable — Don’t alert the user before this date. Notification: When the device should buzz/ping the user — Meaning that they can get started on the task. Due Date: Hard deadline — If the system works well, tasks are meant to rarely be past-deadline; productivity systems are about meeting deadlines rather than about missing them. The EventKit Reality Here is what I’m seeing in practice, and I’m hoping someone can correct me if I’m wrong: Field Description In Practice (Reminders App) startDateComponents Docs say "start date of the task" Seemingly unused? I can set it via API, but the Reminders app UI ignores it. It doesn't seem to trigger visibility in "Today" or Smart Lists. dueDateComponents Docs say "date by which reminder should be completed" Conflated. Acts as the "Date" you see in the list. It functions as the Start Date (shows in Today), Due Date (turns red tomorrow), AND Notification time (unless early alerts are set). alarms Inherited from EKCalendarItem seems to be used for the actual notifications, including "Early Reminders," but tightly coupled to the due date in the UI. My Questions: Is startDateComponents effectively a dead field? Is there any native behavior (Smart List filtering, sorting, visibility) that respects this field, or is it purely for metadata storage for third-party apps? Smart List Logic: I was hoping to create a Smart List that shows "Actionable" items (i.e., Start Date <= Today). However, the Smart List filters only offer a generic "Date" field, which maps to dueDateComponents. Has anyone successfully filtered by startDateComponents in a native Smart List? Conflation: Is there any "blessed" way to set a Due Date that is distinct from the Notification time without fighting the system? (e.g. Due Friday, but remind me Wednesday). Any insight into the intended semantics here would be huge. I'm trying to avoid fighting the framework, but the "One Date to Rule Them All" approach in the Reminders app is making it tricky to support separate Start/Due dates. Thanks!

Hi there, I have a plan of creating another app in the same niche, but I would like the actual subscribers to have access to the new app. So the subscribers of App 1 don't need to subscribe to App 2. Is that possible? Thanks Pedro M.R. Gregorio

Our company sells insurance and we'd like to offer annual renewals via Apple Pay on the Web. Most of the docs seem to point towards using recurringpaymentrequest but this method required an amount value which would only be calculated at renewal time. It appears that Shopify is doing something akin to what we want where they do auto payments so my question is can we do annual payments with unknown renewal prices with Apple Pay for Web ? What we cannot do is show the renewal price like this as it being insurance is almost certain to change. This is our current code which works but won't get past the regulator. const applePayPaymentRequestAnnual = { countryCode: 'GB', currencyCode: 'GBP', supportedNetworks: ['visa', 'masterCard'], merchantCapabilities: ['supports3DS'], requiredBillingContactFields: ['postalAddress', 'email'], requiredShippingContactFields: ['phone'], recurringPaymentRequest: { paymentDescription: 'Annual Insurance Renewal', regularBilling: { label: 'Annual Renewal Premium', amount: price, paymentTiming: "recurring", recurringPaymentIntervalUnit: "year", recurringPaymentStartDate: year + "-" + month + "-" + day + "T00:00:00.000Z", type: 'final' }, managementURL: window.location.protocol + '//' + window.location.host + '/manage-policy', tokenNotificationURL: window.location.protocol + '//' + window.location.host + '/apple-pay-notifications' }, lineItems: [{ label: alabel, amount: price, }], total: { label: alabel, amount: price, type: "final" }, }

We are seeing a strange lifecycle issue on multiple MDM-managed iPads where application(_:didFinishLaunchingWithOptions:) is not called after the device is idle overnight. Even if we terminate the app manually via the app switcher, the next morning the system does not perform a cold launch. Instead, the app resumes directly in: applicationDidBecomeActive(_:) This causes all initialization logic that depends on didFinishLaunching to be completely skipped. This behavior is consistent across four different supervised MDM devices. Environment Devices: iPads enrolled in MDM (supervised) iOS version: 18.3 Xcode: 16.4 macOS: Sequoia 15.7.2 App type: Standard UIKit iOS app App: Salux Audiometer (App Store app) Expected Behavior If the app was terminated manually using the app switcher, the next launch should: Start a new process Trigger application(_:didFinishLaunchingWithOptions:) Follow the normal cold-start lifecycle Actual Behavior After leaving the iPad idle overnight (8–12 hours): The next launch skips didFinishLaunching The app resumes directly in applicationDidBecomeActive No new process is started App behaves as if it had been suspended, even though it was manually terminated Logs (Relevant Extracts) Day 1 — Normal cold launch [12:06:44.152 PM] PROCESS_STARTED [12:06:44.214 PM] DID_FINISH_LAUNCHING_START launchOptions=[] [12:06:44.448 PM] DID_FINISH_LAUNCHING_END We then used the app and terminated it via app switcher. Day 2 — Unexpected resume without cold start [12:57:49.328 PM] APP_DID_BECOME_ACTIVE No PROCESS_STARTED No didFinishLaunching No cold-start logs This means the OS resumed the app from a previous state that should not exist. Reproducible Steps Use an MDM-enrolled iPad. Launch the app normally. Terminate it manually via the multitasking app switcher. Leave the device idle overnight (8–12 hours). Launch the app the next morning. Observe that: didFinishLaunching does not fire applicationDidBecomeActive fires directly Questions for Apple Engineers / Community Is this expected behavior on MDM-supervised devices in iOS 18? Are there any known OS-level changes where terminated apps may be revived from disk/memory? Could MDM restrictions or background restoration policies override app termination? How can we ensure that our app always performs a clean initialization when launched after a long idle period? Additional Information We have full logs from four separate MDM iPads showing identical behavior. Happy to share a minimal reproducible sample if required.

We are facing a DNS resolution issue with a specific ISP, where our domain name does not resolve correctly using the system DNS. However, the same domain works as expected when a custom DNS resolver is used. On Android, this is straightforward to handle by configuring a custom DNS implementation using OkHttp / Retrofit. I am trying to implement a functionally equivalent solution in native iOS (Swift / SwiftUI). Android Reference (Working Behavior) : val dns = DnsOverHttps.Builder() .client(OkHttpClient()) .url("https://cloudflare-dns.com/dns-query".toHttpUrl()) .bootstrapDnsHosts(InetAddress.getByName("1.1.1.1")) .build() OkHttpClient.Builder() .dns(dns) .build() Attempted iOS Approach I attempted the following approach : Resolve the domain to an IP address programmatically (using DNS over HTTPS) Connect directly to the resolved IP address Set the original domain in the Host HTTP header DNS Resolution via DoH : func resolveDomain(domain: String) async throws -> String {     guard let url = URL(         string: "https://cloudflare-dns.com/dns-query?name=\(domain)&type=A"     ) else {         throw URLError(.badURL)     }     var request = URLRequest(url: url)     request.setValue("application/dns-json", forHTTPHeaderField: "accept")     let (data, _) = try await URLSession.shared.data(for: request)     let response = try JSONDecoder().decode(DNSResponse.self, from: data)     guard let ip = response.Answer?.first?.data else {         throw URLError(.cannotFindHost)     }     return ip } API Call Using Resolved IP :  func callAPIUsingCustomDNS() async throws {     let ip = try await resolveDomain(domain: "example.com")     guard let url = URL(string: "https://(ip)") else {         throw URLError(.badURL)     }     let configuration = URLSessionConfiguration.ephemeral     let session = URLSession(         configuration: configuration,         delegate: CustomURLSessionDelegate(originalHost: "example.com"),         delegateQueue: .main     )     var request = URLRequest(url: url)     request.setValue("example.com", forHTTPHeaderField: "Host")     let (_, response) = try await session.data(for: request)     print("Success: (response)") } Problem Encountered When connecting via the IP address, the TLS handshake fails with the following error: Error Domain=NSURLErrorDomain Code=-1200 "A TLS error caused the secure connection to fail." This appears to happen because iOS sends the IP address as the Server Name Indication (SNI) during the TLS handshake, while the server’s certificate is issued for the domain name. Custom URLSessionDelegate Attempt :  class CustomURLSessionDelegate: NSObject, URLSessionDelegate {     let originalHost: String     init(originalHost: String) {         self.originalHost = originalHost     }     func urlSession(         _ session: URLSession,         didReceive challenge: URLAuthenticationChallenge,         completionHandler: @escaping (URLSession.AuthChallengeDisposition, URLCredential?) -> Void     ) {         guard challenge.protectionSpace.authenticationMethod == NSURLAuthenticationMethodServerTrust,               let serverTrust = challenge.protectionSpace.serverTrust else {             completionHandler(.performDefaultHandling, nil)             return         }         let sslPolicy = SecPolicyCreateSSL(true, originalHost as CFString)         let basicPolicy = SecPolicyCreateBasicX509()         SecTrustSetPolicies(serverTrust, [sslPolicy, basicPolicy] as CFArray)         var error: CFError?         if SecTrustEvaluateWithError(serverTrust, &error) {             completionHandler(.useCredential, URLCredential(trust: serverTrust))         } else {             completionHandler(.cancelAuthenticationChallenge, nil)         }     } } However, TLS validation still fails because the SNI remains the IP address, not the domain. I would appreciate guidance on the supported and App Store–compliant way to handle ISP-specific DNS resolution issues on iOS. If custom DNS or SNI configuration is not supported, what alternative architectural approaches are recommended by Apple?

I have a standalone Apple Watch app that uses Bluetooth with the bluetooth-central background mode. It seems that in watchOS 26.2, once the system terminates the BLE connection after background allowance is exceeded, the app never regains background BLE capability, even after the user returns to the foreground and interacts with it. This contradicts the documentation and the WWDC22 “Get timely alerts from Bluetooth devices on watchOS” session, which state that background BLE connectivity should be restored when the user brings the app back to the foreground. Does anyone have any insight into this behavior?

Recent our APP performance online has revealed significant degradation in cellular network SRTT (Smoothed Round-Trip Time) on the latest iPhone models (iPhone 18.1, 18.2, and 18.3) relative to previous generation devices. IDC network transmission SRTT P50 increased by 10.64%, P95 increased by 103.41%; CDN network transmission SRTT P50 increased by 12.66%, P95 increased by 81.08%. Detailed Performance Metrics: 1. Network Transmission SRTT Degradation Following optimization of our APP's network library, iOS network transmission SRTT showed improvement from mid-August through mid-September. However, starting September 16, cellular network SRTT metrics began to degrade (SRTT increased). This degradation affects both IDC and CDN routes. WiFi network performance remains unaffected. 2. Excluding iOS 26.x Version Data After data filtering, we discovered that the increase in iOS cellular network transmission SRTT was caused by data samples from iOS 26.x versions. When excluding iOS 26.x version data, network transmission SRTT shows no growth. 3. Comparative Analysis: iOS 26.x vs. iOS < 26.0 network transmission SRTT shows： IDC (Internet Data Center) Links: P50 latency: 10.64% increase / P95 latency: 103.41% increase CDN (Content Delivery Network) Links: P50 latency: 12.66% increase / P95 latency: 81.08% increase 4. Device-Model Analysis: iOS 26.x SRTT Degradation Scope Granular analysis of iOS 26.x samples across different device models reveals that network SRTT degradation is not universal but rather specific to certain iPhone models. These measurements indicate a substantial regression in network performance across both data center and content delivery pathways.

Hello everybody! I'm currently working on a Bluetooth Low Energy Sync that is using BGTaskScheduler & successfully running periodically in the Background on iOS 26. I did watch this years WWDC Session 227 (Finish tasks in the background) & follow the recommendations as suggested. Currently, the App is only using 37 Mb (iPhone 12 mini) & no Location or other services are running in Background. However, when opening Safari & scrolling through some webpages, the App is killed because of "Terminated due to memory issue". I profiled the App & followed advice when it comes to reducing the memory footprint of the App. Are there any additional steps I can take to prevent the App being killed? Are there any recommendations for periodically scheduled Tasks when it comes to the Interval? Do more frequent Tasks (30min compared to one or two hours) have any impact? I tried many different schedules but none seem to make a difference. From my observation, the App is first suspended & eventually killed because of the Memory Pressure. Any hints, suggestions or recommendations are highly appreciated! Thanks a lot for the support!

Hello, I have tried a lot to get AlarmKit to work from a controlwidget without first going into the app. So far, I have not been successful unless I also opened the app on clicking the controlwidget. Is this a known limitation?

Hello, We are encountering an issue where invoking our App Clip via a Safari Smart App Banner fails on certain devices, particularly those running iOS 26. When a user taps "Open" on the Smart App Banner, the App Clip card attempts to load but ultimately fails with ASDErrorDomain Error 507. The error occurs consistently on specific devices, while other devices function correctly. In some instances, the App Clip card metadata/UI appears momentarily (flashes on the screen) before the error message is displayed and the process terminates. Has anyone else experienced this specific ASDErrorDomain error? We have already submitted a report via Feedback Assistant, but any insights or workarounds from the community would be appreciated. Thanks!

I’m trying to fully understand the purpose of the ageGates parameter in the AgeRangeService.requestAgeRange API. The official documentation includes the following statement: “The system may return geo-specific age ranges that override your provided age gates based on the person’s location and applicable regulations. When geo-specific ranges are required, the returned age range reflects regulatory requirements rather than the bounds of your age gates.” Based on this, it seems that even if my app provides specific age thresholds through the ageGates parameter, the system may override those boundaries depending on regional laws or regulations, and return a completely different lowerBound / upperBound than what my age gates would suggest. My current understanding is: ageGates indicates the thresholds my app uses to define its internal feature tiers, but the actual age range returned by the OS is determined by legal or regional requirements (e.g., COPPA, GDPR-K, AADC, SB2420), meaning the returned age range may not align with the age ranges implied by my ageGates values. I’d like to confirm whether this interpretation is correct. Additionally, if different regions may produce different lowerBound / upperBound values due to regulatory requirements, then it seems that: developers shouldn’t rely on fixed age buckets, and instead must implement feature gating logic dynamically based on whatever age range the OS returns. So my questions are: Is my understanding correct that ageGates is simply a hint that describes my app’s tier thresholds, and the OS may override those boundaries to comply with local regulations? If lowerBound / upperBound can vary across regions, what is the recommended way for developers to design their feature-gating logic? Should we avoid hardcoded age buckets and instead build flexible logic that adapts to whatever range the OS returns? I’d appreciate clarification so I can design our age-based policies appropriately and in a regulation-compliant way.

In iOS 26.1, after my app answers a VoIP call on the lock screen, tapping the bottom-left "More" button doesn't bring up the app icon to jump to the app. The same scenario works normally on iOS 26. How can I resolve this issue?

In iOS AP-mode onboarding for IOT devices, why does the iPhone sometimes stay stuck on the device Wi-Fi (no internet) and fail to route packets to the device’s local IP, even though SSID is correct? Sub-questions to include: • Is this an iOS Wi-Fi auto-join priority issue? • Can AP networks become “sticky” after multiple joins? • How does iOS choose the active routing interface when Wi-Fi has no gateway? • Why does the packet never reach the device even though NWPath shows WiFi = satisfied?

What is the best way to detect if the Wifi is being used for Wireless Carplay or is just a normal network interface?

Hi Team, We have a requirement for device-to-device communication using the Multipeer Connectivity framework without requiring Wi- Fi connectivity. Current Status: Multipeer communication works successfully when Wi-Fi is enabled Connection fails when using Bluetooth-only (Wi-Fi disabled, in Airplane Mode) Concern: We've found forum suggesting that Multipeer Connectivity over Bluetooth-only has been restricted since iOS 11, despite Apple's documentation stating support for both Wi-Fi and Bluetooth transports. Request: Could you please confirm: Whether Bluetooth-only Multipeer Connectivity is officially supported in current iOS versions( iOS 18.0+)? If there are specific configurations or entitlements required for Bluetooth-only operation? Any known limitations or alternative approaches for offline device-to-device communication? This clarification will help us determine the appropriate implementation strategy for our offline communication requirements. Thank you.

Hi there, I'm trying to work on an architecture where one app exposes an API (Extension Host) that other apps can plugin to. I've been reading all I can from the docs and whatever I can find online. It seemed like iOS26 added the ability to do such a thing (at least in early builds). Is that the case? Has the functionality been walked back such that extensions can only be loaded in iOS from within the single app bundle? My use case is the following: I'm working on an agent app that desires to have 3rd party developers add functionality (think how MCP servers add functionality to LLMs). The 3rd party plugins would be provided in their own app bundles vetted by the AppStore review team, of course, and would only provide hooks, basically, the main app can use to execute functions or get state. This is the best thread I found on the topic, and the subtext is that it needs to be in the same bundle. https://developer.apple.com/forums/thread/803896?answerId=865314022#865314022 Let's say for the moment that this isn't possible using ExtensionKit. What's the best way to achieve this? Our current best alternative idea is a hidded WebKit window that runs JS/WASM but that's so hackish. Please let me know, thanks!

We are using the MPNowPlayingInfoCenter API to provide information to the “Now Playing” system UI. This works as expected, except that when the app is manually terminated, the information is removed from the UI. Our question is: Some apps (for example, Audible) are able to appear in the “Recently Played” section of the UI. This section seems to show a history of apps that previously provided “Now Playing” information but are not currently playing anything. We would like to know which API is used to achieve this behavior.

In macOS, how can I use UnmutableNotificationContent notifications to prevent the main window from activating when clicking the notification? code： import Cocoa import UserNotifications // Mandatory import for notification functionality class ViewController: NSViewController { override func viewDidLoad() { super.viewDidLoad() // Automatically request permissions and send a test notification when the view loads sendLocalNotification() } /// Core method to send a local notification func sendLocalNotification() { let notificationCenter = UNUserNotificationCenter.current() // 1. Request notification permissions (Mandatory step; user approval required) notificationCenter.requestAuthorization(options: [.alert, .sound, .badge]) { [weak self] isGranted, error in guard let self = self else { return } // Handle permission request errors if let error = error { print("Permission request failed: \(error.localizedDescription)") return } // Exit if user denies permission if !isGranted { print("User denied notification permissions; cannot send notifications") return } // 2. Construct notification content using UNMutableNotificationContent let notificationContent = UNMutableNotificationContent() notificationContent.title = "Swift Notification Test" // Notification title notificationContent.subtitle = "macOS Local Notification" // Optional subtitle notificationContent.body = "This is a notification created with UNMutableNotificationContent" // Main content notificationContent.sound = .default // Optional notification sound (set to nil for no sound) notificationContent.badge = 1 // Optional app icon badge (set to nil for no badge) // 3. Set trigger condition (here: "trigger after 3 seconds"; can also use time/calendar triggers) let notificationTrigger = UNTimeIntervalNotificationTrigger( timeInterval: 3, // Delay in seconds repeats: false // Whether to repeat (false = one-time only) ) // 4. Create a notification request (requires a unique ID for later cancellation if needed) let notificationRequest = UNNotificationRequest( identifier: "SwiftMacNotification_001", // Unique identifier content: notificationContent, trigger: notificationTrigger ) // 5. Add the request to the notification center and wait for triggering notificationCenter.add(notificationRequest) { error in if let error = error { print("Notification delivery failed: \(error.localizedDescription)") } else { print("Notification added to queue; will trigger in 3 seconds") } } } } }

iPhone 15 Pro Max and similar models are unable to connect to the AP configuration hotspot broadcast by an IoT oven equipped with the MediaTek MT7682 chip. The connection interface remains in a spinning/loading state indefinitely, preventing the completion of the device’s network provisioning workflow.
