How to determine if a cold start is a background launch when using SceneDelegate (scene-based lifecycle)
(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { if (application.applicationState == UIApplicationStateBackground) { // ✅ Background launch } else { // ✅ Normal foreground launch } } Previously, when using AppDelegate to handle lifecycle methods, I could determine whether a cold start was a background launch as shown above. This allowed me to accurately measure cold start time for real-world users. The platform now requires migration to scene-based lifecycle management by iOS 16. However, after migration: In both application:didFinishLaunchingWithOptions: and scene:willConnectToSession:options: methods, application.applicationState == UIApplicationStateBackground and scene.activationState == UISceneActivationStateUnattached These values remain fixed regardless of whether it's a background launch, making them unusable for differentiation. I attempted to use information from UISceneConnectionOptions for distinction but found it ineffective. Question: Are there alternative approaches to achieve this distinction?

Battery stuck at 1% after installing iOS 26 beta 2 – device only usable when plugged in, battery capacity shows 0%
After installing iOS 26 Developer Beta on my iPhone 13 mini, I encountered a critical battery issue. The battery percentage was stuck at 1%, and the phone could only be used while continuously plugged in. Despite the low reading, the device remained fully functional — I could use apps, navigate, and perform tasks normally. However, the battery indicator never rose above 1%, and the Battery Health section in Settings showed 0% Maximum Capacity, which is inaccurate. I did not allow the phone to fully discharge, out of fear that it might not turn back on. Restarting the phone and changing cables or chargers had no effect. After restoring the device to iOS 18.7.2 using DFU mode, the issue disappeared entirely — the battery percentage behaved normally again and the health section showed the correct value (about 100%). Observed behavior: • Battery percentage frozen at 1% • Maximum Capacity reported as 0% • Device only functional while connected to power • Issue resolved immediately after restoring to iOS 18 Temporary solution: A DFU restore to iOS 18 (18.5 22F76) immediately resolved the issue. The battery percentage and health readings returned to normal. Additional information: • Charger used: Official Apple 20W USB-C charger • Cable used: Apple USB-C to Lightning cable • Battery health after restore: 100% (replaced)

accessibilityRespondsToUserInteraction return true on Simulator but false on device
I am seeing a strange issue where NSObject accessibilityRespondsToUserInteraction returns true on Simulator but false on device. Checking the same object on simulator with Accessibility inspector I see the object traits as image so why would it return true in that case? Are there any other way to check the the item might be accessibilityRespondsToUserInteraction OR Clickable beside that property and traits? (Or is it just another bug)

External Keyboard + Voiceover focus not working with .searchable + List
While editing the search text using the external keyboard (with VoiceOver on), if I try to navigate the to List using the keyboard, the focus jumps back to the search field immediately, preventing selection of list items. It's important to note that the voiceover navigation alone without a keyboard works as expected. It’s as if the List never gains focus—every attempt to move focus lands back on the search field. The code: struct ContentView: View { @State var searchText = "" let items = ["Apple", "Banana", "Cherry", "Date", "Elderberry", "Fig", "Grape"] var filteredItems: [String] { if searchText.isEmpty { return items } else { return items.filter { $0.localizedCaseInsensitiveContains(searchText) } } } var body: some View { if #available(iOS 16.0, *) { NavigationStack { List(filteredItems, id: \.self) { item in Text(item) } .navigationTitle("Fruits") .searchable(text: $searchText) } } else { NavigationView { List(filteredItems, id: \.self) { item in Text(item) } .navigationTitle("Fruits") .searchable(text: $searchText) } } } }

Enable NFC Access for Argentina’s SUBE Transit App on iPhone
Hello Apple Developer Community and Apple Team, I want to raise awareness and gather support for an important feature request regarding NFC support on iPhone devices in Argentina. Millions of Argentinians use the official public transit card, SUBE, daily to pay for buses, subways, and trains. On Android devices, the SUBE app allows users to: • Check balance via NFC • Reload credit instantly • Confirm top-ups by holding the card near the phone • Use a digital version of the card (in some cases) However, iPhone users cannot use these NFC features because iOS currently does not allow third-party apps like SUBE to access the NFC chip fully. This limitation negatively impacts iPhone users, many of whom rely heavily on SUBE. I have submitted detailed feedback to Apple requesting the enablement of controlled NFC access for third-party transit apps in Argentina, starting with SUBE. I encourage fellow developers, users, and community members to support this request. Enabling this would greatly improve the user experience for millions of iPhone users, align Apple with local needs, and potentially attract new customers from Android. If anyone has insights or updates on this topic, please share. Thank you.

Can `UIApplication.shared.setAlternateIconName` use .icon file?
I’m updating my app’s alternate icons using UIApplication.shared.setAlternateIconName, and I noticed that in iOS 26, Xcode now supports the new .icon file format for App Icons. Is it possible to reference .icon files directly for alternate icons? Or does setAlternateIconName still only support traditional .png assets inside the AppIcon set? I couldn’t find any documentation confirming this either way, and I want to ensure compatibility with the new format while supporting alternate icons. Any clarification or Apple documentation link would be greatly appreciated!

How to donate IndexedEntity, if required in iOS 26
In the Get to Know App Intents WWDC session, it was said New this year, you can now add Spotlight indexing keys directly on properties. Annotating properties allows Spotlight to show more relevant information to customers. When donating indexed entities, the framework will handle creating the searchable item and attribute set for you. After donating entities, they can be found in Spotlight. How do you donate indexed app entities? Making app entities available in Spotlight seems to state it's not necessary to donate entities: The system can automatically extract the keys for Spotlight indexing at compile time and store them in the App Intents metadata that Xcode generates as part of your app’s bundle. As a result, Spotlight indexing is faster and can find your app entities without launching your app, and without you having to explicitly donate the entities to Spotlight. You also don’t need to manually update or remove entities from the Spotlight index when your app’s data changes. Say I have a CarEntity. The user can create/update/delete cars at any time. What is the modern way to get cars to appear in Spotlight in iOS 26?

Cannot recreate reason for app rejection
An update to my app has been rejected under Guideline 2.1 - Performance - App Completeness, citing that only a blank screen appeared on launch. I cannot recreate this bug. I have, on this exact device and iOS version that the reviewer used (iPhone 13 mini, iOS 18.5): Downloaded the app from TestFlight and successfully launched Launched in release mode Launched as a new install AND as an upgrade Launched with no internet, good internet and slow internet I have asked the reviewer for any crash logs and more detail about the testing setup that led to this blank screen on launch, and no extra information was provided at all, just another screenshot of the launch screen. Where do I go from here? Any advice would be hugely appreciated.

Is there any API for real-time Wi-Fi connection monitoring?
We are developing an iOS application with a key feature designed to enhance user safety: real-time assessment of Wi-Fi network security. The "Safe Wi-Fi" feature aims to inform users about the security level of the Wi-Fi network they are currently connected to. Our goal is to provide this information seamlessly and continuously, even when the user isn't actively using the app. Currently, we've implemented this feature using a NWPathMonitor. The limitation of NWPathMonitor is that it doesn't function when the app is in a kill state. We are looking for guidance on how to achieve persistent Wi-Fi security monitoring in the background or when the app is killed. Is there any API (Public, Special API, etc) or a recommended approach that allows for real-time Wi-Fi connection monitoring (including connection changes and network details) even when the app is not actively running or is in a kill state. Thank you in advance for your help.

iOS App udp and local network permission
Recently, my application was having trouble sending udp messages after it was reinstalled. The cause of the problem was initially that I did not grant local network permissions when I reinstalled, I was aware of the problem, so udp worked fine after I granted permissions. However, the next time I repeat the previous operation, I also do not grant local network permissions, and then turn it back on in the Settings, and udp does not work properly (no messages can be sent, the system version and code have not changed). Fortunately, udp worked after rebooting the phone, and more importantly, I was able to repeat the problem many times. So I want to know if the process between when I re-uninstall the app and deny local network permissions, and when I turn it back on in Settings, is that permissions have been granted normally, and not fake, and not required a reboot to reset something for udp to take effect. I'm not sure if it's the system, or if it's a similar situation as described here, hopefully that will help me find out

Displaying limited contacts list in UIKit
I have an app that was written in UIKit. It's too large, and it would be much too time consuming at this point to convert it to SwiftUI. I want to incorporate the new limited contacts into this app. The way it's currently written everything works fine except for showing the limited contacts in the contact picker. I have downloaded and gone though the Apple tutorial app but I'm having trouble thinking it through into UIKit. After a couple of hours I decided I need help. I understand I need to pull the contact IDs of the contacts that are in the limited contacts list. Not sure how to do that or how to get it to display in the picker. Any help would be greatly appreciated. func requestAccess(completionHandler: @escaping (_ accessGranted: Bool) -> Void) { switch CNContactStore.authorizationStatus(for: .contacts) { case .authorized: completionHandler(true) case .denied: showSettingsAlert(completionHandler) case .restricted, .notDetermined: CNContactStore().requestAccess(for: .contacts) { granted, error in if granted { completionHandler(true) } else { DispatchQueue.main.async { [weak self] in self?.showSettingsAlert(completionHandler) } } } // iOS 18 only case .limited: completionHandler(true) @unknown default: break } } // A text field that displays the name of the chosen contact @IBAction func contact_Fld_Tapped(_ sender: TextField_Designable) { sender.resignFirstResponder() // The contact ID that is saved to the Db getTheCurrentContactID() let theAlert = UIAlertController(title: K.Titles.chooseAContact, message: nil, preferredStyle: .actionSheet) // Create a new contact let addContact = UIAlertAction(title: K.Titles.newContact, style: .default) { [weak self] _ in self?.requestAccess { _ in let openContact = CNContact() let vc = CNContactViewController(forNewContact: openContact) vc.delegate = self // this delegate CNContactViewControllerDelegate DispatchQueue.main.async { self?.present(UINavigationController(rootViewController: vc), animated: true) } } } let getContact = UIAlertAction(title: K.Titles.fromContacts, style: .default) { [weak self] _ in self?.requestAccess { _ in self?.contactPicker.delegate = self DispatchQueue.main.async { self?.present(self!.contactPicker, animated: true) } } } let editBtn = UIAlertAction(title: K.Titles.editContact, style: .default) { [weak self] _ in self?.requestAccess { _ in let store = CNContactStore() var vc = CNContactViewController() do { let descriptor = CNContactViewController.descriptorForRequiredKeys() let editContact = try store.unifiedContact(withIdentifier: self!.oldContactID, keysToFetch: [descriptor]) vc = CNContactViewController(for: editContact) } catch { print("Getting contact to edit failed: \(self!.VC_String) \(error)") } vc.delegate = self // delegate for CNContactViewControllerDelegate self?.navigationController?.isNavigationBarHidden = false self?.navigationController?.navigationItem.hidesBackButton = false self?.navigationController?.pushViewController(vc, animated: true) } } let cancel = UIAlertAction(title: K.Titles.cancel, style: .cancel) { _ in } if oldContactID.isEmpty { editBtn.isEnabled = false } theAlert.addAction(getContact) // Select from contacts theAlert.addAction(addContact) // Create new contact theAlert.addAction(editBtn) // Edit this contact theAlert.addAction(cancel) let popOver = theAlert.popoverPresentationController popOver?.sourceView = sender popOver?.sourceRect = sender.bounds popOver?.permittedArrowDirections = .any present(theAlert,animated: true) } func requestAccess(completionHandler: @escaping (_ accessGranted: Bool) -> Void) { switch CNContactStore.authorizationStatus(for: .contacts) { case .authorized: completionHandler(true) case .denied: showSettingsAlert(completionHandler) case .restricted, .notDetermined: CNContactStore().requestAccess(for: .contacts) { granted, error in if granted { completionHandler(true) } else { DispatchQueue.main.async { [weak self] in self?.showSettingsAlert(completionHandler) } } } // iOS 18 only case .limited: completionHandler(true) @unknown default: break } } // MARK: - Contact Picker Delegate extension AddEdit_Quote_VC: CNContactPickerDelegate { func contactPicker(_ picker: CNContactPickerViewController, didSelect contact: CNContact) { selectedContactID = contact.identifier let company: String = contact.organizationName let companyText = company == "" ?

HealthKit returns different values depending on the OS the request is made on
Hi, I've had trouble for a while now with HealthKit giving me different values if I make the request on iOS and WatchOS. I am using the exact same method on both with the same parameters but I get vast differences in the results. The code I am using to call HealthKit on both devices is: let dateRange = HKQuery.predicateForSamples(withStart: Date().removeMonths(numberOfMonths: 1), end: Date().endOfDay()) let predicate: NSPredicate predicate = NSCompoundPredicate(type: .and, subpredicates: [dateRange]) let query = HKStatisticsQuery(quantityType: HKQuantityType(.stepCount), quantitySamplePredicate: predicate, options: .cumulativeSum) { _, result, error in if error != nil { //print("Error fetching step count, or there is no data: \(error.localizedDescription), \(startDate) -> \(endDate)") onComplete(0) return } if let result, let sum = result.sumQuantity() { let stepCount = sum.doubleValue(for: HKUnit.count()) DispatchQueue.main.async { onComplete(Int(stepCount)) } } } healthStore.execute(query) }
