Inquiry About Deferred Deep Link Limitation and Alternative Options
Dear Apple Support Team, I hope this message finds you well. I’m reaching out to inquire about the limitations of deferred deep linking within iOS applications. Specifically, I’m interested in understanding the constraints and challenges that prevent deferred deep links from functioning as expected in certain scenarios (e.g., when the app is not installed or other related issues). Additionally, I would like to ask if there are any recommended alternative approaches or solutions to implement deep linking, ensuring that users can still be directed to specific content or screens even if they need to install the app first. Your insights and guidance would be greatly appreciated as I work to enhance the user experience in my app. Thank you for your time and assistance. Best regards, Santosh

Reliable Shield enforcement for Parental Control App when child disables Notifications
We're building a parental control app using FamilyControls (.child authorization). Our architecture: Parent sends pause command → Firestore + FCM Child receives push → NotificationService Extension triggers main app Main app sets ManagedSettings Shields Problem: If child disables Notifications in Settings and force-quits the app, we cannot enforce Shields. What we've tried: Firestore Realtime Listener (works only when app is running) DeviceActivityMonitor (intervalDidStart/End only triggers at schedule boundaries, eventDidReachThreshold requires explicit app selection via FamilyActivityPicker) Question: Is there a recommended approach for parental control apps to reliably enforce Shields when the child has disabled notifications? Or is this a known limitation?

How to install macOS Tahoe 26 on an external drive
In the past I was always able to install every major macOS version on an external drive so that I can test my apps. But now I'm unable to install macOS Tahoe 26 on an external drive. Actually, as far as I'm aware, there are not even official links to macOS 26 installers, but only instructions on how to update to macOS 26 from an existing macOS installation. So I thought I'd install macOS 15 on a separate drive and then update to macOS 26, but whenever I run the macOS 15 installer, tell it to install on the external drive, and reboot after the setup process completes, my MacBook just boots into my main macOS partition as if nothing happened. 3 months ago I somehow managed to install macOS Tahoe beta 1 on an external drive, I don't remember how (but I don't think it was anything crazy); booting into that beta 1 partition and trying to update doesn't work either, as my MacBook again boots into my main macOS partition. I already asked help about the update problem one month ago here, but nobody replied. Could someone at Apple please provide instructions on how one is supposed to install macOS 26 on an external drive (if possible before it becomes available to the public)? Are we supposed to buy a separate Mac for every macOS version that we want to test our apps on?

FamilyActivitySelection tokens are invalid for other members in family sharing network
I'm currently working with the FamilyControls API and testing my app on two different devices. Both apps are in the same family-sharing network with one phone being the owner of the network (I'll call this A) and the other one being an adult in the network(I'll call this B). When device A picks apps using the FamilyActivityPicker, it shares that selection with device B (via encoding, sending over network, and decoding on device B). However, interacting with the token (displaying it, using it in shield) throws an error saying the token is null. From the documentation, I thought every token would be the same across all devices in the family sharing network. So my question: How do I send the FamilyActivitySelection from A to B and have the tokens still be functional? Does this functionality only work if A is a "parent" and B is a "child" in the family sharing network? Also, side note: If I reverse the process and send the tokens from B to A. Interacting with the token works exactly as expected. For some reason, it's only going from A to B where it doesn't work.

WeatherKit fails on AppStore
Hello, After being in the AppStore for more than a year with the app working perfectly, yesterday I started seeing that WeatherKit requests failed with Failed to generate jwt token for: com.apple.weatherkit.authservice with error: Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)" Encountered an error when fetching weather data subset; location=<+41.40217108,+2.20023642> +/- 0.00m (speed -1.00 mps / course -1.00) @ 13/12/25, 12:20:35 Central European Standard Time, error=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors 2 Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)" I checked on developer.apple.com and we still have everything turned on and No changes were made from an already deployed app; and we pay 200$ a month for WeatherKit, this is unacceptable since it's not the first time WeatherKit randomly decides to stop working. More fun facts: the widget works fine...

Apple Media Service T&C pop-up
I had published an App which App Clip is supported. I have receipt complaints from user where the user will keep showing the "Apple Media Services Terms and Conditions Have Changed" right after user click on the "Open" button in the App Clips. What I had tried: Let user switch the current logged in Apple Id region to one of our support region. Log out and log in with an Apple Id which had no issue.

3rd-party closed-source XCFramework security
Hey! I am developing a macOS application with the help of an external vendor, who is supplying me with a closed-source XCFramework. In Xcode, when I import their XCFramework bundle, when running the app, or opening a SwiftUI preview, or interacting with the app in any form, I get the familiar dialog: "[SDK name].framework" Not Opened - Apple could not verify "[SDK name].framework" is free from malware that may harm your Mac or compromise privacy. (Regardless, the application can run on my machine.) But indeed, their cross-platform iOS/macOS XCFramework is not notarized at all (using spctl -a -t install), plus the macOS binary embedded is not code signed correctly (using codesign -d). The XCFramework itself is production code signed with a Developer ID certificate, however I believed the above issues to be valid. Now, I asked the vendor to provide a correctly distributed (so code signed and notarized) framework, however they pointed out that "when I embed and sign the product in my app, it will be re-signed anyways". I understand this is true, but I believe this to be an important security boundary. If I were to re-sign under my name a closed source binary - previously unchecked for malware by Apple Notary Service -, I would put myself up for embedding potentially malicious code in my app, which could only be traced back to me - which would in turn mean a security issue would hinder my reputation here. Am I being over-protective here, or is this a valid concern? I have no way to see the source code, so I strongly believe this XCFramework should be notarized correctly. I understand that an in-house XCFramework is fine unnotarized, given that I know its origin, but this seems like a unique case where notarization should be enforced from my side on the vendor.

Activating a Container App from a Custom Keyboard Extension to Enable Continuous Voice Input While Preserving the Original Typing Context
Project Background: I am developing a third-party custom keyboard for iOS whose primary feature is real-time voice input. In my current design, responsibilities are split as follows: 1. The container (main) app is responsible for: Audio recording Speech recognition (ASR) 2. The keyboard extension is responsible for: Providing the keyboard UI Initiating the voice input workflow Receiving transcription results via an App Group Inserting recognized text into the active text field using textDocumentProxy.insertText(_:) Intended User Flow The intended workflow is: The user is typing in a third-party app (for example, WeChat) using my custom keyboard. The user taps a “Voice Input” button in the keyboard extension. The keyboard extension activates the container app so that audio recording and ASR can begin. After recording has started, control returns to the original app where the user was typing. The container app continues running in the background, maintaining active audio recording and ASR. Recognized text is continuously streamed back to the keyboard extension and inserted into the current cursor position in real time. Observed Industry Behavior Some popular third-party keyboards on iOS, such as WeChat Keyboard and Doubao Keyboard, appear to provide a similar user experience in which: Voice input can be initiated directly from the keyboard while typing in another app. The user remains (or returns) in the original typing context after voice input starts. Speech recognition continues and text is streamed into the active text field without interrupting the typing experience. I would like to better understand how this type of workflow aligns with iOS platform capabilities and supported APIs. My Questions Is it supported by iOS public APIs for a custom keyboard extension to activate its container app to start audio recording and ASR, then return to the original host app while the container app continues recording and performing ASR in the background? If this workflow is not supported, are there any Apple-recommended or supported alternative architectures for achieving a similar user experience, especially when audio recording and ASR logic are currently implemented in the container app rather than in the keyboard extension? Goal My goal is to design a solution that is fully compliant with iOS public APIs and platform constraints, while providing a real-time voice input experience comparable to existing third-party keyboards on the platform. Any guidance on supported APIs, recommended architectures, or relevant documentation would be greatly appreciated.

SCREEN TIME API is reporting false positives to DeviceActivityMonitor extension in iOS 26.2 & 26.3
Since the iOS 26.2 update, we have been experiencing anomalous behavior with the DeviceActivityMonitor extension when utilizing the ScreenTime API. Specifically, we are receiving the eventDidReachThreshold event within a few minutes of initiating monitoring, despite configuring a high usage limit. The process of turning off Screen Time -> restarting the device -> turning on Screen Time does not work. Any ideas? Thanks Filed Feedback Assistant: FB21560904

Using MetricKit for Hangs on macOS
Hallo all, I did a test integration of MetricKit into one of our apps...I'am on macOS Ventura 13.3.1 (a). The app is not distributed via the App Store. I subscribed to the MXMetricManager and implemented the didReceiveDiagnosticPayloads function. So far everything seems to work, when I use in Xcode: Debug -> Simulate MetricKit Payload I get a callback and the payload. So I did some further testing. When I build the app debug version with a test crash and then run the Debug Version (without Xcode) and let it crash the next time I start the app I get a callback to didReceiveDiagnosticPayloads with all the information about the crash. But I'am not able to get a hang report. I tested it by adding a sleep (60) and adding some intensive computation work on the main thread so that it is busy for several seconds, I get no hang reports :-( I'am using the Debug version and run it without Xcode. Are hang reports expected to be reported immediately? I also get after 24 hours no hang reports. Can someone help me? Thanks and have a nice day!

Clarification Needed: histogrammedTimeToFirstDraw vs histogrammedOptimizedTimeToFirstDraw in MetricKit
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.

Add 'PDF Services' symlink in ~/Library directory in SwiftUI macOS Catalyst application
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.)

Misleading iOS prompt claims developers "will receive" user data
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

Detecting host app bundle ID from keyboard extension to enable "return to app" after deep link
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.

WeatherKit: WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 on iOS 26.2 (Simulator & Device)
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()

Hallo all, I did a test integration of MetricKit into one of our apps...I'am on macOS Ventura 13.3.1 (a). The app is not distributed via the App Store. I subscribed to the MXMetricManager and implemented the didReceiveDiagnosticPayloads function. So far everything seems to work, when I use in Xcode: Debug -> Simulate MetricKit Payload I get a callback and the payload. So I did some further testing. When I build the app debug version with a test crash and then run the Debug Version (without Xcode) and let it crash the next time I start the app I get a callback to didReceiveDiagnosticPayloads with all the information about the crash. But I'am not able to get a hang report. I tested it by adding a sleep (60) and adding some intensive computation work on the main thread so that it is busy for several seconds, I get no hang reports :-( I'am using the Debug version and run it without Xcode. Are hang reports expected to be reported immediately? I also get after 24 hours no hang reports. Can someone help me? Thanks and have a nice day!

Clarification Needed: histogrammedTimeToFirstDraw vs histogrammedOptimizedTimeToFirstDraw in MetricKit
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.

AlarmKit - Is it possible to disable snoozing?
Hi, I didn't find any mentions in the doc about disabling the option for snoozing in an alarm. Although you can create an alarm without a snooze button using AlarmKit, the user can still snooze by clicking on the volume button, for example.

Add 'PDF Services' symlink in ~/Library directory in SwiftUI macOS Catalyst application
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.)

Misleading iOS prompt claims developers "will receive" user data
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

Detecting host app bundle ID from keyboard extension to enable "return to app" after deep link
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.

WeatherKit: WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 on iOS 26.2 (Simulator & Device)
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()
