Dear fellow iOS developers, I am interested in UWB technology and I am trying to build a dummy Indoor Navigation project. I will be placing 3 third party UWB devices (hardware or chips) at some distance apart from each other. I have 5 iPhones and I want to be able to connect all the 5 iPhones to the 3 UWB devices simultaneously and perform trilateration to get the iPhones x and y coordinates using the "distance" values obtained from the UWB devices (hardware or chips). I have tried this approach using Qorvo DWM3000 chips but problem is that after the first iPhone connection, the chip stops advertising itself. Is this approach possible? Also, it is compulsory to establish NISessions? Can't I skip creating NISessions? Thanks in advance. Forgive my english.

My use case is a Repeat Timer app. The user can configure a repeating timer, say: 8 minutes with 3 sets So I would like to configure either 3 alarms (8mins, 16mins, 24mins) or a repeating alarm (8mins every 3 mins) BUT... I would like the first and second alarms to break through but only for 5 seconds for example, and then stop (so the user doesn't need to tap the screen to silence the alarm). I don't think this is possible after reading the API docs, but am asking the question anyway. Thanks for any advice or guidance here, and happy WWDC!

The data displayed about a child’s apps can be outdated (DeviceActivityReport), leading to misinformation for the user. When I access the “Screen Time” section (for child in the parent device) in the iPhone settings, I see there is an update functionality to force load the actual data. I have tried various workarounds, such as attempting to force an update on the child’s device to call DeviceActivityReport and opening system settings, but none of these have been successful :( How can I implement something similar? Is there a way to force update this data ?

Is there any way to use the screen time API on Mac?

If I have, say a doctor appointment in the Calendar app, and I'm leaving to go to it, the address will appear in Apple Maps on CarPlay. Forgive if I'm getting the details wrong, but I believe if I bring up the Map, it will be available to tap on, so I can quickly go there. I think it may also show up on one on the car-play screens that shows a few different panels. The point is, I really like this feature, and want to do it in my app. In my iOS app, the user can order food from a restaurant, and pick it up. I'm not ready to make this app a "quick service" app, but I want to give the user an easy to get to her location. Since I just ordered food, this means that I'll need to leave fairly quickly to go to the location. The Calendar app is able to offer a location because of scheduling, I'd like to do the same.

After a user has launched an App Clip Experience from Safari and is done with the activity that the App Clip provides – is there a way for the App Clip to programatically close itself so the user returns to Safari?

Wouldn’t it be nice to have a folder of apps specifically tied to the use of your focus? For instance, I work for a delivery company and we have about 3 apps for it. My s/o has about 5 to 8 apps for her job as well. It would be nice to to have them all in a centralized spot when in “Work“ Focus. What do you think?

I’m creating an app with the Screen Time API and I would like to know how to make the app show a parental control editing view for parents and a view for child accounts that shows which apps are blocked. How can I do this?

I've created a font family, but Font Book refuses to include it in the English language set, despite my best efforts. The font has every glyph in the OpenType "Std" set, plus several others. I've checked various boxes for Latin 1 and Macintosh Character Codepages; plus Unicode ranges for Basic Latin, additional Latin, etc, etc. I've compared it to several other fonts that are in the English set, and I can't see anything that they have that my fonts don't. (In fact, many of them seem to have much less!) I've created other fonts that are in the English set, but I've no idea what the difference is. Given that macOS relies on these Language sets, in order to hide the thousands of unnecessary fonts that are permanently installed in the OS, there ought to be some guidance on how to do this.

I'm using FamilyActivityPicker to get consent for app/category management, which returns a FamilyActivitySelection object. I serialize this FamilyActivitySelection object (just applicationTokens and categoryTokens) and pass it to my DeviceActivityMonitor extension via App Group UserDefaults. I am using the JSON encoder/decoder over PropertyList (though both seem to exhibit the same behavior). After inspecting the FamilyActivitySelection object immediately after it's returned by FamilyActivityPicker in the main app, the application.bundleIdentifier property is consistently nil for every Application object within selection.applications. Similarly, category.localizedDisplayName is nil for ActivityCategory objects. This happens whether "Select All Apps" is used or if apps/categories are selected individually. I understand that this is the intended behavior due to Apple's user privacy policies. I read on another post that my app can be provided with bundle identifiers and app names within Shield Configuration extensions and Device Activity Report extensions - I'm not sure which ones or how exactly to do this. I am aware that I can use Label(applicationToken) SwiftUI view to display the app name/icon, but this doesn't give programmatic access to the bundleIdentifier string. My app will not log or export these bundleIdentifiers outside of its sandbox. My goal is to create mappings to the FamilyActivitySelection with the publicly accessible bundleIdentifiers. Any guidance, examples, or clarification on the intended workflow for this scenario would be greatly appreciated!

How can I show my VoIP calling app in the same list as Facetime and Whatsapp as shown in the image? My app implements VoIP calls and is integrated with CallKit. Any tip would be appreciated!

Hi Apple engineering team, I’m trying to integrate the new Live Caller ID Lookup (PIR) on iOS using your pir-service-example code as well as a custom mock server in Vapor, but the extension never advances past the /issue/token-key-for-user-token step. I’ve tried both: 1. Official Example Cloned https://github.com/apple/pir-service-example Ran PIRService locally Confirmed that GET /.well-known/private-token-issuer-directory → 200 GET /issue/token-key-for-user-token → 200 (DER bytes, correct SPKI) No POST /issue ever fires 2. Mock Server (Vapor) Implemented all five endpoints (/config, /.well-known/private-token-issuer-directory, /issue/token-key-for-user-token, /issue, /queries) Verified with curl and openssl asn1parse that: GET /.well-known/private-token-issuer-directory Content-Type: application/private-token-issuer-directory { "issuer-request-uri":"https://…/issue", "token-keys":[…] } GET /issue/token-key-for-user-token Content-Type: application/octet-stream <DER bytes> Added Cache-Control: public, max-age=3600 on directory and SPKI Stubbed POST /issue to always return { "token": "" } Still no POST /issue request from the extension Reproduction Steps Install and enable a Live Lookup extension pointing to my server. Trigger an incoming call on device. Watch server logs—only see the two GETs, never /issue or /queries. Expected Behavior After fetching the SPKI DER, the framework should issue a POST /issue call (Privacy Pass flow) and then POST /queries. Observed Behavior Stuck in an infinite loop of: GET /.well-known/private-token-issuer-directory GET /issue/token-key-for-user-token (repeat…) No progression to the /issue or /queries endpoints. What I’ve Tried Verified JSON kebab-case and headers exactly match examples Confirmed SPKI DER is valid via openssl asn1parse Added Cache-Control headers Tested on real device, localhost url, and ngrok public URL Mocked a valid-looking token response Could you advise what additional requirement or format detail I’m missing that prevents from advancing past /issue/token-key-for-user-token? These are the main files: LiveLookupExtension.swift routes.swift service-config.json Thanks in advance!

在watchOS11.5下，Apple watch无法加载天气。无论是否连接自己的iPhone均无法加载

Goal: Manually install an explicit version of Rosetta2 Background: Me and some customers have an old app (intel) which perfectly worked with Rosetta2. In the last week of April most macheines were updated to Mac Os 15.4.1. and the app still starts but certain functionality is bronken. Some fields ind the forms don't write back to the database, some data can't be read from the database. (Most installations will fade out over the next month but it would be great to have the app fully working for data migration.) First try was to step back to 15.4. (Clean Install - Install App - Rosetta installs as expected): no change, app still broken Second try back to 15: (Clean Install - Install App - Rosetta installs as expected): App still broken (!) This is interesting as the app worked for month using Mac Os 15! Third try: Back to MacOS 14 (Clean Install - Install App - Rosetta installs as expected): App is working like nothing happend. (All attempts on same hardware of course.) Reasoning: Rosetta2 was the only software (besides the app itself) installed after clean MacOS installs. Now, my guess is that there were might be a change in Rosetta2 as the app worked on MacOs 15 up the update 15.4.1. was installed. Checking versions (pkgutil --pkg-info com.apple.pkg.RosettaUpdateAuto): Rosetta version MacOS 14: 1.0.0.0.1.1722778371 Rosetta version on MacOS 15.4.1: 1.0.0.0.1.1744447383 To fully verify the cause it would be great to uninstall Rosetta on MacOS15.4.1 machine and explicit install lower version (1.0.0.0.1.1722778371) which must be available somewhere as MacOS14 still gets this version. I know how to uninstall - is there a possibility to manually install an explicit version of Rosetta2?

Hello, I have a question related to the public iTunes Search API: https://performance-partners.apple.com/search-api Do all the books have an ISBN associated? I used to do queries like: https://itunes.apple.com/lookup?isbn=9781501110368. That book is available on Apple Books here: https://books.apple.com/us/book/it-ends-with-us/id1052928247 and the endpoint above returns informations about it. However for newer books like: https://itunes.apple.com/lookup?isbn=9781419766954 https://itunes.apple.com/lookup?isbn=9781250288776 Nothing comes back anymore even if those books exist there. The url's for the 2 above are: https://books.apple.com/us/book/hot-mess-diary-of-a-wimpy-kid-19/id6476554491 https://books.apple.com/mt/book/the-mirror/id6474420363 For newer books starting the beginning of September 2024, nothing seems to come back when you search them by ISBN. Thanks

How can I use the Screen Time API to set a restriction for a child account from my app running on the parent’s account?

My CoreSpotlight extension seems to exceed the 6 MB memory limit. What’s the best way to debug this? I've tried to attach the debugger on the Simulator but the extension seems to be never launched when I trigger the reindex from Developer settings. Is this supposed to work? On device, I am able to attach the debugger. However, I can neither transfer the debug session to Instruments, nor display the memory graph. So I've no idea how the memory is used. Any recommendations how to move forward? Is there a way to temporarily disable the memory limit since even with LLDB attached, the extension is killed.

We developed a "Default Translation App" following the guide: https://developer.apple.com/documentation/translationuiprovider/preparing-your-app-to-be-the-default-translation-app. I have already configured everything that needs to be configured according to the document, but there is still this problem

Hi everyone, I’m developing a screen-time and focus app that uses Apple’s Family Controls framework to block distracting apps and reward users through a gamified experience. Apple approved Family Controls (Distribution) for the main app identifier, but they did not approve the required extension target (which implements DeviceActivityMonitor, required for the framework to function). Because of this, I can’t archive or upload the app to TestFlight — and I’ve been stuck in limbo for over 2 months. This is severely delaying my launch. The app works perfectly, but I can’t release it because the extension wasn’t included in the entitlement approval. Has anyone else run into this with Family Controls? Is there any known way to escalate or fast-track approval for additional app IDs or targets? Would really appreciate any help, advice, or hacks. 🙏 Thanks, Enzer

We've been using the WeatherKit API for a few years now. Everything has been pretty stable. We'll periodically get 404 errors, but they usually disappear within a couple days. Starting March 5th we've again been getting 404 errors that slowly ramped up to March 20th and continued. We have had no code changes on our end, so something seems to have changed / broken on the server side of things. Here are some example API calls that are giving us a 404 error now https://weatherkit.apple.com/api/v1/weather/en/35.9981205/-78.8920444?dataSets=forecastDaily&dailyStart=2025-03-21T05:00:00Z&timezone=America/New_York&countryCode=US https://weatherkit.apple.com/api/v1/weather/en/41.4789363/-81.7404134?dataSets=forecastDaily&dailyStart=2025-03-21T04:56:00Z&timezone=America/New_York&countryCode=US Does anyone have any insights or information on this? Also if Apple is listening, an error more meaningful than 404 would be much much appreciated.
