Crashes with Rosetta after Sonoma update (crash reports).
Hello. We have an app and a custom dylib hat seems to be crashing only when Rosetta is involved. I believe it's the custom DYLIB that crashes. Here are some observations. The issue happens on the older 2022 built DYLIB (Intel only) And the newer DYLIB built (Universal) The universal DYLIB works fine natively on both Intel and M1 machines. It's only when we access it through an Intel only .app and it's running with Rosetta that we see the crash. The older Intel only .DYLIB worked perfectly with the same testing .app in versions before Sonoma, now they crash with the same .app, same build. Crash reports have been all over the place, they vary but repeat themselves. It has been a little confusing as to how to approach this issue and would appreciate any input that can help us understand what is going wrong and how to move forward. Crash reports are attached Crash Report 1 Crash Report 2 Crash Report 3 The crash occurs as SIGSEGV Version: 2.0 (1) Code Type: X86-64 (Translated) Parent Process: launchd [1] User ID: 501 Date/Time: 2025-04-14 19:55:06.0103 +0200 OS Version: macOS 14.6 (23G5075b) Report Version: 12 Anonymous UUID: A08ECCFA-BF01-8636-7453-E4476586D3A8 Time Awake Since Boot: 3900 seconds System Integrity Protection: enabled Notes: PC register does not match crashing frame (0x0 vs 0x102920144) Crashed Thread: 10 Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x000000011d052840 Exception Codes: 0x0000000000000001, 0x000000011d052840 Termination Reason: Namespace SIGNAL, Code 11 Segmentation fault: 11 Terminating Process: exc handler [3174] VM Region Info: 0x11d052840 is not in any region.

Universal Links not working with subdomains without AASA on root domain
Hi all, I'm trying to set up universal links for my app but it's not working. What I want: cogover.com → Safari (website) - NOT my app *.cogover.com (any subdomain like abc.cogover.com) → My app What I did: Added applinks:*.cogover.com in Xcode Put AASA files on all subdomains They work fine (checked with curl) Problem: All links still open in Safari, not my app. I do not put AASA on my root domain cogover.com because I don't want open my app with root domain. I have checked TN3155: Debugging universal links | Apple Developer Documentation but it only say about universal link works with both root domain and subdomains. Weird thing I found: I checked how Salesforce does it - their *.force.com subdomains work perfectly. But when I tried to check their setup, (https://force.com/.well-known/apple-app-site-association) doesn't seem to exist either! So how does theirs work? Even stranger - Apple's CDN has their file cached at (https://app-site-association.cdn-apple.com/a/v1/force.com) but the actual domain doesn't serve it. Can Apple's CDN have a file cached even if it's not on the website anymore? Thanks for any help!

[macos 15.2 (24C101)] Custom input method does not work as expected
Environment: macOS 15.2 (24C101) with Xcode 16.2 (16C5032a) Goal: I am trying to build a simple IMKInputController-based input method. Problem: My .app bundle registers successfully and I can select it as an input source. When selected, it blocks keyboard input, but my handle method does not seem to execute or produce output. I have placed NSLog statements in my controller's init and handle methods. Code for the controller: import InputMethodKit // The IMKTextInput protocol is provided by the framework. // We don't need to define our own bridging protocol for this test. public class HelloWorldController: IMKInputController { public override init!(server: IMKServer!, delegate: Any!, client inputClient: Any!) { super.init(server: server, delegate: delegate, client: inputClient) NSLog("HelloWorldIME: Controller has been initialized.") } public override func handle(_ event: NSEvent!, client sender: Any!) -> Bool { NSLog("HelloWorldIME: handle() method was called.") // ================== FINAL FIX APPLIED HERE ================== // 1. First, we ensure the client is a fundamental Objective-C object. guard let clientObject = sender as? NSObject else { NSLog("HelloWorldIME: Error - client object is not an NSObject.") return false } NSLog("HelloWorldIME: Successfully cast client to NSObject.") // 2. Now that we have an NSObject, we can safely check if it responds to the selector. let selector = #selector(IMKTextInput.insertText(_:replacementRange:)) if !clientObject.responds(to: selector) { NSLog("HelloWorldIME: Error - client object does not respond to the insertText selector.") return false } NSLog("HelloWorldIME: Client responds to insertText. Preparing to insert text.") // 3. Since we've confirmed it responds, we can now safely treat it as an IMKTextInput // and call the method. let client = clientObject as! IMKTextInput let stringToInsert = "A" let replacementRange = NSRange(location: NSNotFound, length: 0) client.insertText(stringToInsert, replacementRange: replacementRange) NSLog("HelloWorldIME: Called insertText with string '\(stringToInsert)'. Action complete.") // ======================================================== return true } }

How does an app like Jomo access Screen Time data on parent devices (not just child devices)?
Hi all, I'm working on a Screen Time-based app with gamification features for families, where both children and parents interact and compare usage stats. The endgoal of the app is to motivate for less screentime or more use of productive apps. I'm testing Apple's Family Controls API, which works great for getting data from child devices. However, this API doesn't support fetching screen time data on the parent device itself. Apps like Jomo appear to provide insights and even their own "calculations" on screen time usage directly on the parent device. I have tested a few apps that showed both the usage data for my children and myself and did some nice things with it like creating stats. I've gone through the documentation and APIs extensively, but I can’t figure out how they’re doing this. As far as I can tell the only solution would be a custom VPN or MDM. However as far as I can tell Jomo for example does not use either of those. My questions are: Am I missing some API Are apps like Jomo using private APIs which they have been granted access to from Apple? Is there any way to access similar data on a parent device without using MDM or VPN? Any guidance or clarification would be greatly appreciated!

Issue with UWB ranging on DWM3001CDK using NINearbyAccessoryConfiguration in Background mode
Hi, I’m trying to perform UWB ranging between an iPhone and a Qorvo DWM3001CDK accessory using Apple NI’s NINearbyAccessoryConfiguration class. I’ve followed the steps described in the official Apple documentation (https://developer.apple.com/documentation/nearbyinteraction/ninearbyaccessoryconfiguration), specifically for enabling background mode using the init(accessoryData:bluetoothPeerIdentifier:) initializer. The configuration is successfully created, and background mode is enabled. However, when the iPhone starts the session, I doesn’t receive any ranging data from the DWM3001CDK, and the session ends with a timeout. Interestingly, if I use the init(data:) initializer, I can successfully receive ranging data, but this only works in foreground mode, which doesn’t meet my requirements. Steps I’ve followed: Used Core Bluetooth to discover and pair the accessory. Retrieved the configuration data from the accessory according to the third-party UWB device specifications. Initialized the configuration using NINearbyAccessoryConfiguration(accessoryData:bluetoothPeerIdentifier:) for background mode. Started the session with NISession.run(configuration). Waited for updates in the delegate method session(_:didUpdate:). Specific questions: Are there additional requirements for using init(accessoryData:bluetoothPeerIdentifier:) to enable background UWB ranging with the DWM3001CDK? Is there a known difference in how init(data:) and init(accessoryData:bluetoothPeerIdentifier:) handle the ranging process? Any advice or insights would be greatly appreciated. Thanks in advance!

SetFocusFilterIntent `perform()` method is not called on iOS 18 beta
I’ve set up a focus filter, but the perform() method in SetFocusFilterIntent isn't called when the focus mode is toggled on or off on my iPhone since I updated to iOS 18 beta (22A5326f). I can reproduce the issue for my app, but focus filters are also broken for any third-party apps installed on my phone, so I guess it's not specific to how I've implemented my filter intent. This used to work perfectly on iOS 17. I didn't change a single line of code, and it broke completely on the latest iOS 18 beta. I've filed a bug report including a sysdiagnose (FB14715113). To the developers out there, is this something you are also observing in your apps?

Video button on CallKit UI is disabled for Video VoIP call, only on notch devices.
We've observed an issue where the video button on the CallKit UI is disabled during Video VoIP calls. This issue appears to be specific to notch devices running SDK 26 and iOS 26 beta 7, specifically on iPhone 11. We have not seen this behavior on devices with Dynamic Island or on older iOS versions. For further details, please refer to the attached video and sysdiagnose file. : FB19827793 Our experimentation suggests this issue is exclusively present on non-Dynamic Island devices with iOS 26 beta.

Couple simple suggestions to make WKExtendedRuntimeSession a lot better
I just launched my watch app with alarms using WKExtendedRuntimeSession, as an api I wish it was possible to: set a small title/message on the alarm ui itself, right now all it displays is the "Alarm from < app name >" with the app icon, but it would be nice to be able to set a short 1~2 line message below it as well! be able to read the current scheduled date, right now it's only possible to know it's scheduled.

iOS magnetometer data processing
Hello, I’m developing an app to detect movement past a strong magnet, targeting both Android and iOS. On Android, I’m using the Sensor API, which provides calibrated readings with temperature compensation, factory (or online) soft-iron calibration, and online hard-iron calibration. The equivalent on iOS appears to be the CMCalibratedMagneticField data from the CoreMotion framework. However, I’m encountering an issue with the iOS implementation. The magnetometer data on iOS behaves erratically compared to Android. While Android produces perfectly symmetric peaks, iOS shows visual peaks that report double the magnetic field strength. Additionally, there’s a "pendulum" effect: the field strength rises, drops rapidly, rises again to form a "double peak" structure, and takes a while to return to the local Earth magnetic field average. The peaks on iOS are also asymmetric. I’m wondering if this could be due to sensor fusion algorithms applied by iOS, which might affect the CMCalibratedMagneticField data. Are there other potential reasons for this behavior? Any insights or suggestions would be greatly appreciated. Thank you!

Clarification on ManagedSettings Shield Precedence (Application vs. Category)
I'm encountering what appears to be a specific precedence behavior with ManagedSettingsStore.shield and would appreciate some further clarification. My current understanding is that category-level shields take precedence over individual app allowances. My test involved... Using FamilyActivityPicker to select a single target application (e.g., "Calculator," which falls under the "Utilities" category). Using FamilyActivityPicker again to select the category of that target application. I applied shields using ManagedSettingsStore (named .individual): store.shield.applicationCategories = .specific(Set([utilitiesCategoryToken])) store.shield.applications = Set([calculatorApplicationToken]) Result: The calculator app remains shielded, suggesting that the category-level shield on Utilities overrides the attempt to allow the individual app. I also tried this using a single picker, but received only the category token instead of all application tokens in that category. Is this observed precedence (where store.shield.applicationCategories effectively overrides store.shield.applications for apps within the shielded category) the intended behavior? If so, are there any mechanisms available within the main app's capabilities (potentially using a Device Activity Report Extension or Shield Extension) to allow a specific ApplicationToken if its corresponding ActivityCategoryToken is part of the store.shield.applicationCategories set? Essentially, can store.shield.applications be used to create "allow exceptions" for individual apps that fall into an otherwise shielded category? Additionally, I mentioned that selecting an entire category in the picker only returns the opaque category token, not any application tokens. Is there any way in which I could return both the category and all application tokens by just selecting the category? Any insights or pointers would be greatly appreciated!

CSSearchableItemAttributeSet is missing recordingYear
I'd like to set the recordingYear in my Spotlight File Importer extension but the property is missing from CSSearchableItemAttributeSet e.g. in the resulting in mdls I'd like to see: kMDItemRecordingYear = 2008; This would allow me to search in Finder by the recording year criteria. There is a recordingDate property and I tried setting it to Date that only has a year but it didn't work. It just resulted in this: kMDItemRecordingDate = "2008-01-01 00:00:00 +0000";

Delays When Creating Advanced App Clip Experiences for Other Businesses
Hey there, I have an app where I create custom Advanced App Clip Experiences for other businesses which seems to be a valid thing. I do create them via API. Upon creation everything looks fine: when I go to App Store Connect -> App -> Advanced App Clip Experiences, I do see the new App Clip Experience I've just created. Their status is Received (as any other active experiences) and have a custom URL. The issue is weird timing when the Advanced App Clip Experience actually becomes available on the iPhone (can be triggered via App Clip Code, etc). Some experiences become available literally immediately but others take days (some take 1-2 days, some take ~5 days). I'm not sure why there's a bid difference for an Advanced App Clip to be actually active. Does anyone have any kind of experience with that? I don't change domain settings, app's settings, etc. I'm just creating a new experience (both via API or manually at App Store Connect) and I do have different "activation" times for different App Clips. Same when I delete an Advanced App Clip Experience, it will still be available for next couple days. I get there might be caching stuff, etc. But the difference is quite huge and makes no sense since as I've mentioned some clips become available immediately but some takes days to be available. Thank you!

How to properly share code between launch in background and launch in foreground?
I've been reading this question: https://developer.apple.com/forums/thread/701945 and watching the videos on background tasks But can't arrive to a concrete solution. Q1: Are there any tips (or sample app) on how to handle a launch in background in a streamlined way? How to have a shared code that is ran for both 'launch in background' & 'launch in foreground'? Specifically the case I'm talking about is: You set up some observance of some OS callback at a Foo screen of your app. Example app should request and then send push-to-start live activity tokens to server. Or setup location tracking. App is then suspended and then later terminated but is eligible for relaunch App is then launched in background because it has requested a push-to-start live activity token or an update for location tracking. User DOES NOT go back to screen Foo. So at this point app is no longer tracking / listening to updates for token update or location changes. How should I architecture my code for this? I'm trying to see if there's a an approach where I can avoid having multiple places in code where I do the same thing. Currently what I'm doing is as such: Q2: Is it then correct to say that anytime you've launched your app, whether it's in foreground or background then you must immediately match 'all observations done by the previous app launch'? Like store items in UserDefaults and upon launch retrieve them and do: handleGeneralAppLaunchFlow() // ALSO if defaults.contains("didLastLaunchSetupLiveActivtiyTokenObservance") { for await ptsToken in Activity<EmojiRangers> .pushToStartTokenUpdates { ... } } if defaults.contains("didLastLaunchSetupLocationTracking") { locationManager = CLLocationManager() locationManager?.delegate = itsDelegate locationManager?.allowsBackgroundLocationUpdates = true locationManager?.showsBackgroundLocationIndicator = true locationManager?.startUpdatingLocation() } // Other checks for prior observance setup Q3: Actually I think even if app is launched in foreground then because you may not end up at screen Foo again, then you must setup things regardless of app state and just based on prior observations set. Right? Q4: And then later if the user ever made it again to screen Foo, then we just skip the re-do of the observance, or maybe to just keep things simple, we'd just redo without over-engineering things? I tried to mark my questions with Q1- Q4.

Live Caller ID Lookup & PIRService blocking inconsistent
I've successfully started the Live Caller ID Lookup example and initialized the PIRService. I added several identities to the input.txtpb file, some with block: true and others with block: false. Here is the file but modified phone digits: identities { key: "+40790123123" value { name: "Blocking 1" cache_expiry_minutes: 7 block: true } } identities { key: "+972526111111" value { name: "Blocking 2" cache_expiry_minutes: 7 block: true } } identities { key: "+123" value { name: "Adam" cache_expiry_minutes: 8 block: false category: IDENTITY_CATEGORY_PERSON } } identities { key: "+972526111112" value { name: "Identified Business Name 1" cache_expiry_minutes: 1 block: false category: IDENTITY_CATEGORY_BUSINESS } } identities { key: "+972526111113" value { name: "Identified Business Name 2" cache_expiry_minutes: 1 block: false category: IDENTITY_CATEGORY_BUSINESS } } The main issue is that only the number marked as +40790123123 was actually blocked, while "Blocking 2" appeared as identified contacts with their assigned name displayed. Notably, the only blocked number was a foreign number with a different country code than the number being called. The other numbers belonged to the same country. Can someone clarify whether this is a bug in the example project or an issue with the data file?

ContactProviderManager Fails with Custom domainIdentifier, Works Only with "defaultDomain"
Has anyone encountered a situation like mine below? I’ve submitted feedback, but it seems like I’ll have to wait for a while. ContactProviderManager Fails with Custom domainIdentifier, Works Only with "defaultDomain" Category: Developer Tools / Frameworks Subcategory: ContactProvider Framework Reproducibility: Always iOS Version: iOS 18.0 (and later) Xcode Version: Xcode 16.0 (or later)  Description: When initializing a ContactProviderManager with a custom ContactProviderDomain using any identifier other than "defaultDomain", the initializer throws a ContactProviderError.domainNotRegistered error. The documentation for ContactProviderDomain (https://developer.apple.com/documentation/contactprovider/contactproviderdomain) does not provide any method to register custom identifiers, making it impossible to use ContactProviderManager with a desired custom identifier. The only successful case is when the identifier is "defaultDomain". print("Error: (error)") // No error, initialization succeeds Steps to Reproduce: Create a Contact Provider Extension in an iOS app targeting iOS 18.0. In host app, Attempt to initialize a ContactProviderManager with a custom ContactProviderDomain identifier: ​import ContactProvider func enableExtensionExample() async {    do {        // The app creates a contact provider manager with custom domain.        let manager =  try ContactProviderManager(domainIdentifier: "com.mycompany.customdomain")               // May prompt the person to enable the custom domain.        try await manager.enable()    } catch {       print("Error: \(error)") // Prints ContactProviderError.domainNotRegistered    } } Try the same with the default identifier: ​import ContactProvider func enableExtensionExample() async {    do {        // The app creates a contact provider manager with a default domain.        let manager =  try ContactProviderManager(domainIdentifier: "defaultDomain")               // May prompt the person to enable the default domain.        try await manager.enable()    } catch {       print("Error: \(error)") // No error, initialization succeeds    } } Build and run the app on a device or simulator running iOS 18.0 or later. Observe that the initializer fails with domainNotRegistered for any identifier other than "defaultDomain". Expected Behavior: The ContactProviderManager should initialize successfully with any valid ContactProviderDomain identifier, provided the domain is properly configured or registered, allowing developers to use custom identifiers for organizing contacts (e.g., for different categories or sources). Actual Behavior: The ContactProviderManager initializer throws ContactProviderError.domainNotRegistered for any ContactProviderDomain identifier other than "defaultDomain". Only the "defaultDomain" identifier succeeds, limiting the ability to use custom domains. Impact: Developers cannot use custom identifiers to categorize or manage contacts in separate domains, restricting the ContactProvider framework’s flexibility. This forces reliance on the "defaultDomain" identifier, which may not suit use cases requiring distinct contact groups (e.g., personal vs. business contacts). Suggested Fix: Provide an API to register custom ContactProviderDomain identifiers, such as a ContactProviderManager.register(domain:) method. Update the ContactProviderDomain and ContactProviderManager documentation to clarify how to use custom identifiers or explicitly state if only "defaultDomain" is supported. If custom identifiers are not intended to be supported, document this limitation clearly to avoid developer confusion. Feedback : FB20104001 (ContactProviderManager Fails with Custom domainIdentifier, Works Only with "defaultDomain")

Finder Quick Action icon rendering when using custom SF Symbol
Hey folks! I'm working on a macOS app which has a Finder Quick Action extension. It's all working fine, but I'm hitting a weird struggle with getting the icon rendering how I would like, and the docs haven't been able to help me. I want to re-use a custom SF Symbol from my app, so I've copied that from the main app's xcassets bundle to the one in the extension, and configured it for Template rendering. The icon renders in the right click menu in Finder, the Finder preview pane and the Extensions section of System Settings, but all of them render with the wrong colour in dark mode. In light mode they look fine, but in dark mode I would expect a templated icon to be rendered in white, not black. I've attached a variety of screenshots of the icons in the UI and how things are set up in Xcode (both for the symbol in the xcassets bundle, and the Info.plist) I tried reading the docs, searching Google, searching GitHub and even asking the dreaded AI, but it seems like there's not really very much information available about doing icons for Finder extensions, especially ones using a custom SF Symbol, so I would love to know if anyone here has been able to solve this in the past! Finder preview pane in light mode: Finder preview pane in dark mode: Finder quick action context menu: System Settings extension preferences: The custom symbol in my .xcassets bundle: The finder extension's Info.plist:
