I'm trying to fade in the sound used in my alarm app but currently there's no way to achieve this since the alarm sound loops and if i add a fade-in at the beginning of my audio, every time the audio loops the fadein happens.

I see many anti-theft apps already released in the App Store that have a feature to immediately play a loud sound when the charger gets unplugged. I can't find an API to make it work if the app is backgrounded, which is the main point. How can I achieve this?

Its possible to add the Declared Age Range entitlement to extensions, in particular I'm looking at a Notification Service Extension. However the DAR requestAgeRange() API takes a view controller as a parameter. Presumably therefore its not possible for a notification service extension to obtain the age range itself directly? Yes the extension can read it from shared groups if the app reads it and set it into the group. However the scenario I'm thinking of is this: App runs and gets the age range. Sets its functionality accordingly. The server sends pushes which are intercepted by the notification service extension, the extension adjusts its functionality based upon what the app wrote to shared groups The user changes the age range setting, but the app doesn't run. The extension keeps receiving pushes but its functionality is now out of sync with the age range as its not able to obtain it directly

I am still struggling to nail down the screen time between monitoring and showing it in a DeviceActivityReport. It's always off by a couple of percentage points, which results in a difference of a couple of minutes between the time shown for my total screen time in DeviceActivityReport and DeviceActivityMonitor with a threshold set for all apps/websites/categories. In the report, I am looping through all segment (there is only 1 segement using .daily segment interval for a given day) then loop through all categories and all apps within each category and sum up all totalActivityDuration for each app. Based on avaiable documentation, that should corrolate to DeviceActivityMonitor threshold but it doesn't. Are there any differences in how these 2 places count screen time? Are there any apps/core ios services which are excluded from DeviceActivityMonitor. Would appreciate any help at all, I'm losing my mind here. My current suspicion is that Apple Developer documentation is counted twice. i.e. this website https://developer.apple.com/documentation/deviceactivity/deviceactivitymonitor shows up in usage as an App with bundleId of apple.developer.wwdc-release and time spent there is counted twice, against this bundleId AND Safari. I don't know why it's not counted as a webdomain.

We encountered an issue with iOS 26 and release version. We developed a voipout application and we created an entry in native call log on dev/prod version with our app that run under iOS 18.6 and earlier. On iOS 26 TestFlight version didn't create entry in call log but debug version did it. I don't find any clue in CallKit documentation for iOS 26 and we use action.fulfill(withDateStarted: .now) for call and end transaction and we develop under Xcode 26 Do you have any suggestion to solve our problems ?

Hello everyone, I would like to know if there is any way for an iOS app to automatically access a user’s total Screen Time (for example, daily or weekly usage) and then share this with friends so they can compare results, like in a “Screen Time battle”? Thanks you very much for you help!

Hi, We are working to integrate the Live Caller ID Lookup feature into our app. After submitting the request form via the link: https://developer.apple.com/contact/request/live-caller-id-lookup/, we received this reply from Apple: Apple’s OHTTP relay has been configured to talk to your OHTTP gateway. Now Live Caller ID Lookup should work for your application extension when distributed through App Store. However, before officially releasing our app on the App Store, we’d like to make sure the Live Caller ID Lookup feature is working as expected. To test this, we uploaded the app to TestFlight, and it successfully passed App Review. However, the test failed — we observed that the system tries to fetch the config from http://www.example.com/config instead of our actual configuration URL. Questions: Is this expected behavior when using TestFlight? Does the Live Caller ID Lookup feature only become active after full public release on the App Store? Is there any recommended way to test this feature before public release? Thank you!

I want to start the mail application from the development application, but the mail application made by Apple starts. It doesn't work even if I change the default email application to Outlook. When you delete the Apple Mail app, Outlook starts. I want to automatically attach the generated pdf file to the email, but that doesn't work either. Please tell me how to code.

Hello, I have noticed that the ShieldConfiguration is only requested when opening a target app, and never when the application token is moved to a different shield while the target app remains in foreground. This causes problems because many times the wrong ShieldConfiguration is displayed (recycled) instead of requesting a new ShieldConfiguration. This bug has been around since the introduction of the Screen Time API in 2020 and is has not been addressed. Bug reports: FB14237883 FB17902392 Please fix asap!! Not acceptable to have bugs not being addressed for more than 5 years. Most concerning: This is still reproducing on iOS 26 beta 7!! Thanks a lot for your help.

From https://developer.apple.com/forums/thread/803945?answerId=862153022#862153022, the testing of Age Range API was not available through xcode simulator back in Oct 2025. Is this available now? In particular: Is requestAgeRange testing available through simulator? Is requestAgeRange testing with sandbox account available through simulator? Is isEligibleForAgeFeatures available through simulator? Is isEligibleForAgeFeatures testing with sandbox account available through simulator? If the answer is "yes" to any of the above, which version of the xcode and ios version should I use? So far I didn't get any of the above working on the simulator, and I can't find any documentation on the answers above. Thank you!

I'm currently experimenting with AlarmKit and, when configuring an alarm with a Relative schedule, but that never repeats, I find that it is still scheduled in the AlarmManager, but the documentation says that an alarm that has no repeat schedule will be removed from the AlarmManager after firing. This behavior is experienced both in my project and with the sample code AlarmKit-ScheduleAndAlert To reproduce, create a non-repeating alarm, and, after firing, it will still be on the list marked as Scheduled Am I doing something wrong or is this a bug?

I would like to have an AppEntity with a Property that is a Date, which is only the date, not the time. ie the equivalent of 09/14/2025, not 09/14/2025 09:00 UTC How would I model this? How would I create an EntityPropertyQuery for this? If I add QueryProperties they have the UI in Shortcuts pick a time too. Thanks!

Hello, I am building an iMessage extension for my app and I am struggling to figure out how to test it. The extension allows users to send their friends an interactive widget and the recipient experience is very important to test. I tried to do it in the simulators, but simulators do not support iMessage. I have got a second iPhone and created a sandbox account, but I cannot install TestFlight with the sandbox account, as this feature is not supported. Reddit, Stackoverflow, ChatGPT and Apple Developer support also did not help. Can someone share their experience with testing recipient experience in the iMessage extension?

I'm new to the Screen Time API and trying to block custom websites, but I can't get WebDomain tokens to work. When I create a WebDomain like WebDomain(domain: "reddit.com"), the token property is always nil. I have proper authorization and the app works fine for blocking apps, but website blocking just won't work. I'm confused because I see apps like JOMO that let users type in any website domain and successfully block it using Screen Time API. They have the same 49 domain limit and only ask for Screen Time permission, so they must be using the same API I am. But somehow their WebDomain tokens work and mine don't. I've tried creating the tokens right after getting authorization and during the FamilyActivityPicker session, but still get nil. Am I missing some setup step or API call that makes WebDomain tokens valid? Any help would be really appreciated since I'm stuck on this.

Platform and Version iOS Development Environment: Xcode 16.2.0, macOS 15.3 Run-time Configuration: iOS 18.3, 17.x Description of Problem We have started migrating some of the app’s core functionality over to App Intents. Our first release of App Intent support focused on two settings a user can modify on their Bose products, Audio Modes and Immersive Audio, giving users the ability to modify these settings via Siri and shortcuts. The implementation uses two separate shortcuts for each setting type, with each shortcut supporting a single phrase for Siri each: “Change my Bose mode to ” and “Change my Bose immersive audio to ”. Each shortcut uses their own App Intent, and each App Intent has support for optionally providing both a product and a setting when performing the intent. Failing to provide a device, which happens when the intent is performed via Siri, simply auto selects a currently connected Bose product. Failing to provide a setting, like in cases where a user says “Change my Bose ” without providing a setting will simply have Siri confirm the setting the user wants to change before changing the setting. We are using AppEntity to identify a Bose product for both App Intents. Because the App Intent for the Audio Modes setting has a larger number of supported values (up to 15 maximum), we are also using AppEntity to identify these settings. We are using AppEnum to identify available settings for the Immersive Audio App Intent, as only 3 static values are supported. Our original implementation of App Intent support had quite a few phrases supported for each shortcut. We had explicit support for direct synonyms of the verb “Change” in other phrases, supporting words like “Switch” and “Set”. We also had support for words that are like the word “Change”, but not directly related, like the word “Toggle” for instance. We also had support for phrases with or without the setting in each phrase. However, early on we had a lot of trouble with phrase detection with Siri. Siri had a hard time identifying what shortcut was being requested, as well as not being able to identify what settings the user was providing for the setting parameter of each App Intent. While researching potential fixes for this issue, we found a response to a thread in the Apple forums (https://developer.apple.com/forums/thread/759909) that seemed to indicate that Siri phrase recognition was very much an aggregate process. With the total number of phrases supported combined with the available settings for each phrase further compounding the total number of phrases Siri needs to learn to recognize for each shortcut. So, to hopefully improve Siri phrase detection, we added logic to limit the amount of Audio Mode settings supported based on what Audio Modes the user had setup on their Bose products. But, more importantly, we limited the number of explicit phrases supported for each shortcut to just a single phrase. In our testing, not only did this improve phrase recognition, but support for synonyms like “Set” or “Switch” seemed to implicitly still be recognized by Siri. The issues we ran into with Siri phrase detection above has us a bit concerned about scaling App Intent support to other settings and features for our products in the future. Our app supports the ability to modify a large number of settings on their Bose products, with support constantly expanding to new products as they are released. Our roadmap for App Intent support was initially very ambitious, supporting much more than just the two settings mentioned above. But our initial experience with App Intents has us tapering our expectations a little bit as far as how much can be supported in total for App Intents. One thing we also noticed is less than optimal display of default shortcuts in the Shortcuts app. The default shortcuts appeared like so, with shortcuts displayed based on available settings fro each shortcut: However, we could not find a way to indicate to users that one particular section pertained specifically to the Audio Mode setting and the other to the Immersive Audio setting. The only information the user has to make this determination for themselves is the available settings (or shortcuts) for each. This may not be immediately clear to a new customer who might be using one of our products for the first time. This display of default shortcuts in the Shortcuts app has us wondering if our shortcuts implementation is what is intended as far as support for the Shortcuts app is concerned. We did survey default shortcuts displayed by other third-party applications and they mostly dealt with navigation with a single section containing default options clearly indicating where the user can navigate with a shortcut. We couldn’t find an example of an application supporting the ability to change different setting types, with each setting type having their own available values for each. So, to summarize the questions we have concerning App Intent support: What can we do with our App Intents and Shortcuts implementation to guarantee optimal performance with Siri? What is an ideal number of phrases to support for each Shortcut. What limitations should we be placing as far as the total number of available settings for each Shortcut. Are there phrases that might work better than others for what we’re trying to achieve with App Intent support? i.e. Is “Change my Bose mode” or “Change my Bose immersive audio” a good phrase to use for this kind of functionality? Or should we be using different verbs or wording? Assuming optimal support of each Shortcut above. What is a reasonable expectation as far as how many different supported shortcuts we can scale to support at the same time. One issue we ran into early on was Siri confusing one shortcut with the other and triggering the wrong App Intent at times. While this was ultimately resolved, this outcome seems much more likely the greater the number of individual shortcuts supported. Are there any recommendations on how to display these App Intents to customers as far as default shortcuts in the Shortcuts app is concerned? Is what we currently display for default shortcuts in the Shortcuts app what was initially intended for third party support for App Intents? If what we are currently displaying is expected, would it be possible to support the ability to provide additional context to each section of default shortcuts displayed? We would like to indicate to the user that one set of shortcuts pertains to the Audio Modes settings, and the other to Immersive Audio. Something along the lines of a section header like some of the first-party apps use. Are there any recommendations or tips for supporting App Intents, particularly phrases for Siri, in other languages?

I have a public and accessible .well-known/apple-app-site-association file for both my domain.com and subdomain.domain.com with "paths": ["*"] . Both example.com and blog.example.com are added in Associated domains and any link that contains domain.com and domain.com/path normally deep links into my app. I used to have an *.example.com that successfully deep linked all my subdomains into my app but now I had to remove it as some subdomains will need to link to other apps, but some should still link to the same app. I removed * but left blog.example.com as that specific subdomain still needs to deep link into my app. But now blog.example.com is not even being recognized by my app and any link starting with blog.example.com just opens in safari. What am I missing? Why is this happening ?
