Hi Apple Developer Community, I'm implementing MetricKit launch performance tracking in our iOS app and need clarification on two properties: histogrammedTimeToFirstDraw histogrammedOptimizedTimeToFirstDraw The Documentation Problem: The official MetricKit documentation provides minimal explanation of these properties beyond their names. Based on naming conventions, I initially assumed: histogrammedTimeToFirstDraw = cold launches histogrammedOptimizedTimeToFirstDraw = warm/optimized launches Based on our measurements: The “optimized” metric appears only in a small fraction of launches The "optimized" metric is actually slower The naming suggests the opposite behavior Questions: What specific launch conditions does each metric measure? Why would "optimized" launches be slower and less frequent? Is histogrammedOptimizedTimeToFirstDraw related to iOS app pre-warming or prediction features? If these metrics don’t correspond to cold vs. warm launch times, is there an alternative way to measure them accurately? Any clarification from Apple or insights from developers who've tracked these metrics would be greatly appreciated.

Unexpected behavior encountered when scanning NFC tags. Imagine a link shortener web service where users can create lots of different URLs that are hosted on the same domain eg, https://short.com/unique-path The service has optional App Clip capability -- users can select any of their links and have the service create an App Clip for the selected link(s). Users can encode their URLs into NFC tags and have their customers scan NFC tags. Let's take just two URLs for example: https://short.com/foo https://short.com/bar The /foo link does have an App Clip associated with it while /bar does not have it. Each link has been encoded into appropriate NFC tag. Expected behavior when scanning from an iPhone: /foo -- shows an App Clip popup. /bar -- shows a "Open in Safari" default notification. What's actually happening /foo -- opens App Clip poput with correct metadata (title, subtitle, image) which is totally expected behavior. /bar (the one that doesn't have app clip associated with it) -- opens an App-Clip-like popup with the following error: CPSErrorDomainError 2 (see attachment below) So for some reason when someone scans an NFC tag with a URL that is not an App Clip and never has been -- it always shows that error regardless whether the URL exists or does not exist. I've tried few different/random URLs (which don't have an App Clip associated with it) and all of them show the same error. Additional details: All links use the same domain and URL format: domain.com/path where path is a short string of random a-Z characters. All App Clips are created at the same iOS app. AASA is good: Cache and Debug -- both green. This issue has happened to lots of users on lots of different iPhones and iOS'. Since the issue's been happening to lots of different users on different iPhone(s)/iOS' no sysdiagnose is attached. Actually it works the same on every device/iOS we've tried. Before submitting the issue, I've found few other developers reporting the same issue. What's interesting though is none of the links I've went through comes with a definite answer and it seems like this issue just randomly comes and goes without any specific changes on the server and/or iOS app. Dropping the links of similar issues below. https://developer.apple.com/forums/thread/671433 https://developer.apple.com/forums/thread/665969 https://developer.apple.com/forums/thread/775316 https://developer.apple.com/forums/thread/764545

Some Apple URL schemes are documented for third-party use. It’s fine to use those URL schemes for their intended purpose. Other Apple URL schemes are not officially documented. Their use is unsupported. If you rely on such implementation details, things might work, or they might not, and that state might change over time. IMPORTANT If you ship via the App Store, pay attention to clause 2.5.1 of the App Review Guidelines. The Apple URL scheme documentation is not always easy to find. I’m aware of the following: Apple URL Scheme Reference QA1924 Opening Keyboard Settings from a Keyboard Extension [This Q&A was retired years ago.] Preparing your app to be the default messaging app The doc comments for es_new_client in <EndpointSecurity/ESClient.h> Developer > Bug Reporting describes the applefeedback scheme Additionally, as questions about this most commonly crop up in the context of opening Settings (System Settings on macOS), I wanted to highlight the following: UIApplication.openSettingsURLString property (in Objective-C this is UIApplicationOpenSettingsURLString) UIApplication.openNotificationSettingsURLString property (in Objective-C this is UIApplicationOpenNotificationSettingsURLString) UIApplication.openDefaultApplicationsSettingsURLString property (in Objective-C this is UIApplicationOpenDefaultApplicationsSettingsURLString) AccessibilitySettings.openSettings(for:) method FIFinderSyncController.showExtensionManagementInterface() class method SMAppService.openSystemSettingsLoginItems() class method VSOpenTVProviderSettingsURLString global CXCallDirectoryManager.openSettings(completionHandler:) method SFSafariSettings.openExportBrowsingDataSettings() method SFSafariSettings.openExtensionsSettings(forIdentifiers:) method If your app needs to perform some action that’s not covered by the above, file an enhancement request for a supported way to do that.

iOS Intermittent Bug: UserDefaults Preferences Loading Issue Problem Summary We're experiencing an intermittent issue where UserPreferences.shared.preferences returns inconsistent values even after calling getPreferences(). The behavior is unpredictable and affects critical functionality. Environment iOS Version: 15+ Language: Objective-C with Swift interop Storage: UserDefaults with App Group (group.com.jci.tyco.glss) Architecture: Singleton pattern for UserPreferences (Swift class) The Issue When a push notification arrives and triggers the showEvent: method, user preferences are sometimes loaded correctly and sometimes return nil or default values: Scenario A (Works - ~60% of time): Scenario B (Fails - ~40% of time): Observed Pattern From extensive logging over multiple test runs: Key Observation: At app launch: Preferences often load successfully Seconds later when push arrives: Same preferences become unavailable User navigates to another screen and back: Preferences suddenly work again Code Structure Objective-C AppDelegate.m - (void)showEvent:(FMEvent *)event eventReadSource:(FMEventReadSourceType)eventSource { BOOL isUserRoleEndUser = [[FMUserRolesRepository instance] userRoleAvailable:FMUserRoleEndUser]; UserPreferences *userPrefs = [UserPreferences shared]; [userPrefs getPreferences]; // ← Called here // Immediately after, sometimes nil! bool hasFireAudio = [userPrefs.preferences.fireAudio.lowercaseString isEqual:@"true"]; NSLog(@"isUserRoleEndUser: %d | Fire Audio: %d", isUserRoleEndUser, hasFireAudio); // Decision logic based on preferences if ([FMConstants getUserRegion] == UserRegionUK && isUserRoleEndUser && userPrefs.preferences && // ← Sometimes nil here hasFireAudio) { // Show Screen A } else { // Show Screen B } } ```class UserPreferences: NSObject { static let shared = UserPreferences() var preferences: FMUserPreferencesInfo? // ← This becomes nil intermittently func getPreferences() { let userDefaults = UserDefaults(suiteName: "group.com.jci.tyco.glss") if let data = userDefaults?.data(forKey: "UserPreferences") { // Decode and set preferences self.preferences = // decoded object } else { // Create default preferences with fireAudio = "false" self.preferences = FMUserPreferencesInfo() } } }

Hello, Back in January 2024, I filed a bug report regarding a cache being kept by the macOS Wallpaper Agent. This cache contains every image ever set as a users wallpaper, and at the time the issue was reported, it never cleared, leaving hundreds of gigabytes wasted on users disks in some cases. FB13536275 This issue was ultimately fixed in macOS 15.1 beta 6, and remained fixed for the duration of macOS 15. The fix was excellent - the cache was reduced to storing just 2-3 days worth of images. Sadly, we've discovered that this issue is back in macOS Tahoe. The cache has moved locations, and once again is not clearing. We have filed this bug again, less than a year after it was first fixed: FB20636593 We develop an app called 24 Hour Wallpaper that keeps the wallpaper in sync with the time of day. This necessitates that the app regularly changes the wallpaper, which sadly now results in an infinitely growing and useless cache of BMP files generated by the system. As we waited 10 months for this to get fixed the first time, we expect to wait at least that long to get it fixed again, and have no confidence that it will stay fixed because the last fix lasted less than a year. This leaves us in a bad position, as people can't use our app without the cache growing arbitrarily and ultimately completely filling their disk. We've already had customers call Apple to complain about this, and the good news is that the support agents understand that this is a problem with macOS, not with our app. What we've decided to do is add a feature to the app that monitors the size of this cache and periodically deletes it. We're required to get the users permission the first time to do this, but after that the permission is cached, so the app can keep the cache folder clean regardless of if macOS is doing it's job or not. We haven't seen any side effects or problems as a result of doing this. We've seen other apps like CleanMyMac do this without any problems. We're wondering if there is anything we should be aware of regarding this caches behavior before releasing this flushing feature. Thanks for your time, -josh

Hello, Recently we got a question about the keyboard sensor data collection in our research project: "For the typing statistics, was any typing included or only messaging and notes? E.g., typing in the browser, phone search, calendar, etc?" While I believe it should be any typing included, I was not able to find a document explicitly stating that. Could you help to confirm it or guide me to any documentation explaining it? Thanks!

Is there a way to enumerate all files within a folder of an asset pack or just all files in general? My application is using the Apple demo code to load a file from an Apple hosted asset pack: let descriptor = try AssetPackManager.shared.descriptor(for: "NAV/NavData.db3") defer { try descriptor.close() } if let path = path(for: descriptor) { self.database = try Database(path: path) } As my "Navigation Data" is updated each month with an updated asset pack I would like to have the name of the .db3 file reflect the current data cycle (e.g. NAV2601.db3, NAV2602.db3, ...) Ideally I would like to iterate over all files within the NAV folder of the current asset pack and pick the most recent one. Unfortunately, neither the AssetPackManager nor the AssetPack object seem to include an API for this. It would be cool to have something like: let files = try AssetPackManager.shared.files(for: "NAV/") for file in files { //Check and load }

I'm building a voice-to-text keyboard extension that needs to open the main app briefly for audio recording (since keyboard extensions can't record audio), then return the user to their original app. The flow I'm trying to achieve: User is in WhatsApp (or Messages, Slack, etc.) User taps "Voice" button in my keyboard My main app opens via deep link (myapp://keyboard/dictation) App starts recording App automatically returns user to WhatsApp I cannot find a way to detect which app the keyboard is running inside, or which app opened my main app via the deep link. UIInputViewController.textDocumentProxy - No host app information available UIApplication.OpenURLOptionsKey.sourceApplication in application(_:open:options:) - When opened from a keyboard extension, does this return the host app bundle ID or the keyboard extension bundle ID? Private APIs (for research only, not production): _hostBundleID on UIInputViewController - blocked/returns nil on iOS 18 KVC approaches - all blocked Hardcoded app support - Works but requires maintaining a list of popular apps and showing multiple buttons instead of a single "Voice" button My questions: When a keyboard extension triggers a URL open (via SwiftUI Link or UIApplication.shared.open), what does sourceApplication contain? The host app or the keyboard extension? Is there any supported way for a main app to know which app it was launched from, specifically when that launch originated from a keyboard extension? How do apps like "Wispr Flow" achieve seamless return-to-app with a single voice button? They seem to auto-return to whatever app the user was in. Environment: iOS 18.0+ Xcode 16 SwiftUI keyboard using KeyboardKit Any guidance on the recommended approach would be greatly appreciated. I understand there may be privacy reasons for limiting host app detection, but the UX of requiring users to manually swipe back (or tap app-specific buttons) is significantly worse than automatic return.

Hi everyone, We’re running into a serious issue with App Clip Experience updates not propagating to devices, and I’m hoping someone here has encountered (or solved) this before. Problem Once an App Clip Experience is created and used on devices, subsequent updates made in App Store Connect do not reflect on any devices, even after a long period of time. We’ve tried: • Updating the App Clip Experience URL (adding utm parameters, for example, utm_source and scanning via QR code) • Modifying Experience metadata/content • Waiting several days (over a week) • Testing on multiple devices (including devices that never opened the App Clip before) Despite this, the App Clip continues to show the initially created content, while App Store Connect clearly shows the updated configuration. Important Details • We currently have ~1,300 App Clip Experiences created • All App Clips use the same App Clip Bundle ID • The content behind the URLs updates correctly on the website • Only the App Clip continues to show stale / initial data • Removing and re-invoking the App Clip on devices does not consistently fix the issue At this point, manual updates via App Store Connect appear to be completely ignored once the App Clip is “established.” Questions 1. Is there a known hard cache or CDN behavior on Apple’s side that prevents App Clip Experience updates from propagating? 2. Is there any way to invalidate or refresh an existing App Clip Experience? 3. Does having a large number of App Clip Experiences (~1300) affect update behavior or caching? 4. Is the recommended approach to treat App Clip Experience as immutable and handle all updates via backend / dynamic content only? Right now it feels like: App Clip Experience is effectively a one-time snapshot and not a live-updatable configuration. Any insights, confirmations, or official guidance would be greatly appreciated. Thanks in advance.

In my application, I use CallKit and have supportsHolding = true set. During my phone call, another call comes in (e.g., GSM). I accept the incoming call and put the current call on hold. If I end the active call myself, everything is fine, and CallKit calls the method provider(_ provider: CXProvider, didActivate audioSession: AVAudioSession). However, if the other party ends the call, the second call remains on hold. In the application, the user clicks on unhold, and I notify CallKit that the hold has ended. But in this case, the didActivate method is not called at all. If I try to activate the audio myself after unhold, I receive the error: Domain=NSOSStatusErrorDomain Code=561017449 "Session activation failed" UserInfo={NSLocalizedDescription=Session activation failed} AVAudioSessionErrorInsufficientPriority == NSOSStatusErrorDomain Code: 561017449 What needs to be done for CallKit to activate my audio?

I can reproduce the bug that CallKit doesn't active audiosession after the outgoing call put on hold because of an incoming call. VoIP calling with CallKit Steps to reproduce: Download SpeakerBox example app from the link above and start it with XCode Start a new outgoing call Call your phone from other phone Hold and Accept the call After a few secs finish the call from the other phone The outgoing call will be still on hold Click on the call and click Toggle Hold The call won't be active again because the audiosession is activated.

The universal links for my apps stopped working. The server where the AASA files where hosted worked on IPV4 exclusively, a few days ago i changed the configuration to IPV6 only. I´ve created new IPV6 entries, renewed all certifactes and deleted all IPV4 entries for the domains. All seemed fine, but at Saturday I realized that my universal links stopped working for new user. What i´ve done to find the issue: Example domain that was used for debugging: "https://developffw.burns.fun" I´ve verified the AASA file is hosted properly by using different browsers and Postman to retrieve it. The file can be accessed and the certificates look fine. Output of curl -v https://developffw.burns.fun/.well-known/apple-app-site-association * Host developffw.burns.fun:443 was resolved. * IPv6: 2a01:4f8:13b:340a::2 * IPv4: (none) * Trying [2a01:4f8:13b:340a::2]:443... * schannel: disabled automatic use of client certificate * ALPN: curl offers http/1.1 * ALPN: server accepted http/1.1 * Established connection to developffw.burns.fun (2a01:4f8:13b:340a::2 port 443) from 2a00:79c0:65c:8b00:80ee:175b:3e2a:1e7d port 61014 * using HTTP/1.x > GET /.well-known/apple-app-site-association HTTP/1.1 > Host: developffw.burns.fun > User-Agent: curl/8.16.0 > Accept: */* > * Request completely sent off < HTTP/1.1 200 OK < Server: nginx/1.22.1 < Date: Mon, 15 Dec 2025 11:34:22 GMT < Content-Type: application/octet-stream < Content-Length: 329 < Last-Modified: Sat, 21 Dec 2024 08:53:11 GMT < Connection: keep-alive < ETag: "676681f7-149" < Accept-Ranges: bytes < { "applinks": { "details": [ { "appIDs": [ "6LN7G8JEA5.burns.FFW-Manager-SwiftUI.Debug"], "components": [ { "/": "/onboard", "?": { "id": "*"}, "?": { "name": "*"}, "?": { "token": "*" } } ] } ] } } * Connection #0 to host developffw.burns.fun:443 left intact I took a look at the headers from the Apple CDN network response.

I´ve tried sudo swcutil dl -d https://developffw.burns.fun/onboard in the Terminal on my MAC. Output: The operation couldn´t be completed. (SWCErrorDomain error 8.) This indicates to me threre is an issue for the Apple servers accessing my server. But I don´t know what could be the reason. There is no firewall configuration that could block the requests. And there has been no change at all besides the IPV4 / IPV6 protocol change. This issue is the same for all the domain listed on this server. I´v even created a new app for this purpose and created a new AASA entry and associated link. Same issue. I´m pretty much lost here. Everything looks fine from my side. Google assetlinks.json seem to work fine. I would really appreciate some help on how to solve this, i´m at my wits end.

Hello, I am developing an internal phone application using CallKit. I am experiencing an issue with the behavior of remoteHandle settings in iOS 26 and would appreciate any insights you can provide towards a solution. 1. Problem Description When an iPhone running iOS 26 is in a sleep state and receives a VoIP incoming call where remoteHandle is set to nil or an empty string (@""), we are unable to transition to our application (the UIExtension provided by the provider) from the CallKit UI's "More" (…) button after answering the call. 2. Conditions and Symptoms OS Version: iOS 26 Initial State: iPhone is in a sleep state Call Type: An unsolicited(unknown number) VoIP incoming call where the CXCallUpdate's remoteHandle is set to either nil or [[CXHandle alloc] initWithType:CXHandleTypePhoneNumber value:@""] Symptoms: After answering the VoIP call by sliding the button, selecting the "More" (…) button displayed on the CallKit screen does not launch our application's UIExtension (custom UI), and the iPhone instead stay to the CallKit screen. 3. Previous Behavior (Up to iOS 18) Up to iOS 18, even when remoteHandle was set to an empty string using the following code, the application would transition normally from "More" after answering an incoming call from a sleep state. CXCallUpdate *update = [[CXCallUpdate alloc] init]; update.remoteHandle = [[CXHandle alloc] initWithType:CXHandleTypePhoneNumber value:@""]; [provider reportNewIncomingCallWithUUID:uuid update:update completion:completion]; 4. Unsuccessful Attempts to Resolve The issue remained unresolved after changing the handling for unsolicited(unknown number) incoming calls as follows: CXCallUpdate *update = [[CXCallUpdate alloc] init]; update.remoteHandle = nil; // Set remoteHandle to nil [provider reportNewIncomingCallWithUUID:uuid update:update completion:completion]; 5. Workaround (Temporary) The problem can be resolved, and the application can transition successfully, by setting a dummy numerical value (e.g., "0") for the value in remoteHandle using the following code: CXCallUpdate *update = [[CXCallUpdate alloc] init]; update.remoteHandle = [[CXHandle alloc] initWithType:CXHandleTypePhoneNumber value:@"0"]; // Set a dummy numerical value [provider reportNewIncomingCallWithUUID:uuid update:update completion:completion]; 6. Additional Information If remoteHandle is correctly set with the caller's number (i.e., not an unsolicited(unknown number) call; e.g., value:@"1234567890"), the application transitions normally from the "More" button after answering an incoming call from a sleep state, even in iOS 26. The above issue does not occur when answering incoming calls while the iPhone is in an active state (not sleeping). 7. Questions Have there been any other reports of similar behavior? Should this be considered a bug in CallKit for iOS 26? Should I make file a new Feedback report? Is there a suitable method to resolve this issue when the caller ID is unsolicited (nil or an empty string)? This problem significantly impacts user operations as end-users are unable to perform essential in-app actions such as hold or transfer after answering an unsolicited(unknown number) call from a sleep state. We are eager to find an urgent solution and would appreciate any information or advice you can provide. Thank you for your assistance.

I am trying to port my sandboxed macOS app completely over to iOS using a Catalyst target. In my macOS app, I use 'SwiftySandboxFileAccess' package to add a symlink to '~/Library/PDF Services' so that the 'share to my app' menuItem shows up in the macOS Print Panel (in the PDF menu). It is critical for the function of my app to have this work on macOS. In the Catalyst target, I am having problems gaining access to '~/Library'. I have tried having the user select the folder, but the picker always returns 'canceled'. I have a test app that illustrates this. The test app tries to coax the user into selecting the library folder and then it is supposed to bookmark the location, but I am unable to get this far. As an aside, macOS should probably automatically add an entry to the Print Panel when the app includes PDF as a document type in XCode; it would save a lot of hassle and avoid having to go outside of the sandbox. However, I cannot wait for that. Hopefully someone can help. Download Test App from iCloud (If you have problems downloading the file, it might be because of some iCloud share setting that I am not aware of. Just tell me and I'll figure something out.)

The documentation for isEligibleForAgeFeatures states: Use this property to determine whether a person using your app is in an applicable region that requires additional age-related obligations for when you distribute apps on the App Store. But what does "region" mean? Is this going to return true if the user has downloaded the app from the US App Store? Or will it go further and geolocate the user and identify them as being within a particular relevant state within the US?

When a user enables an SMS filtering extension via iOS Settings → Messages → Text Message Filtering and selects an app, the following prompt appears: "The developer of [App Name] will receive the text, attachments and sender information in text messages from senders not in your Contacts. Messages may include personal or sensitive information like bank verification codes." This message cannot be modified by developers, and we're receiving complaints and negative reviews from users who are alarmed by it, despite our app not collecting any data. iOS should allow developers to customize this message or reword this message to not make false claims about data collection. We've opened a feedback assistant report here: FB21445903

Hi all. Thanks in advance for any guidance you’re able to offer. We’ve had an issue reported by multiple customers where, following an iOS update, our app crashes on the next launch. When this happens, users briefly see a split screen: half of the view shows the app background, while the other half is completely black. After this point, the app is unusable. Here’s what we’ve uncovered so far during our investigation: We believe this occurs when a user is already signed into the app at the time they install the iOS update. For context, we intentionally do not force users to log out of the app, as it’s primarily used for customer support and assistance. This is a firm business decision and not something we plan to change. We suspect the issue is related to our Flutter WebView and how it restores or reloads session state following an iOS update. In the past, updating the Flutter version has resolved similar issues, but we are currently on the latest available version. Once the half-screen issue occurs, all app functionality is blocked. At present, the only workaround is for the user to delete and reinstall the app. The most frustrating part is that this does not affect all users. Some customers have updated to iOS 26.2 without any issues at all. We’ve been unable to reproduce the problem internally, despite extensive testing and attempts to force the conditions. That said, our IT Director did experience the issue firsthand on his own device. For our next release, we’re planning to try the following changes, though we won’t know for certain whether they resolve the issue until the update is in the wild. First, disabling iOS state restoration: func application(_ application: UIApplication, shouldSaveApplicationState coder: NSCoder) -> Bool { return false } func application(_ application: UIApplication, shouldRestoreApplicationState coder: NSCoder) -> Bool { return false } This was recommended to us as it’s apparently a common approach to addressing post-update freezes or broken restore states. Second, detecting an iOS version change and resetting the WebView / Flutter state on first launch after an update: let lastOS = UserDefaults.standard.string(forKey: "lastOSVersion") let currentOS = UIDevice.current.systemVersion if lastOS != currentOS { // Clear WebView data WKWebsiteDataStore.default().removeData( ofTypes: WKWebsiteDataStore.allWebsiteDataTypes(), modifiedSince: Date.distantPast, completionHandler: {} ) // Force Flutter engine restart // OR route user through a native splash/login screen UserDefaults.standard.set(currentOS, forKey: "lastOSVersion") } The idea here is to ensure the WebView and Flutter engine start cleanly after an iOS update, rather than attempting to restore potentially incompatible state. We’d really welcome any ideas, suggestions, or feedback from others who may have encountered something similar. Apologies in advance if any details are vague — I’m not deeply technical, so this is based on the research and guidance we’ve gathered so far. Thanks again for your time and help, Chris Brodier

I've been trying to follow Apple's testing age assurance documentation here. After following each step and setting my user as "Texas, child 16-17, significant change declined", the AgeRangeService consistently throws the notAvailable error: do { let response = try await AgeRangeService .shared.requestAgeRange(ageGates: 18, in: self) // ... } catch AgeRangeService.Error.notAvailable { // Always throws this error }

Hello everyone, I’m experiencing a WeatherKit issue that occurs consistently on both the iOS 26.2 Simulator and a real device running iOS 26.2. Environment: Xcode: latest iOS: 26.2 Occurs on: Simulator AND physical device WeatherKit usage: via WeatherService API (not manual REST) Location Services: authorized (When In Use / Always) Issue: WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "The operation couldn’t be completed." Already verified: WeatherKit capability is enabled for the App ID com.apple.developer.weatherkit entitlement is present Bundle ID matches the App ID App is signed with the correct Team ID Behavior is identical on Simulator and physical device Error occurs before any WeatherKit response is returned Questions: Is this a known issue with WeatherKit on iOS 26.2? Are there any known limitations or requirements for WeatherService related to WeatherDaemon validation? Is there a recommended way to diagnose why WeatherDaemon rejects the request with Code=2? Code: private let weatherService = WeatherService()
