The Numbers.app reopens the last edited document when the app launches. If the document was moved to another folder in the Files.app while the app was not running, Numbers.app correctly tracks the file and reopens it. However, if the document was deleted in the Files.app and moved to Recently Deleted, Numbers.app does not reopen the document when the app launches. Question : How does Numbers.app detect that a document has been moved to Recently Deleted? Can third-party apps implement the same behavior? What I tested : If a file is moved while the app is not running, resolving a bookmark successfully tracks the moved file. Files that are deleted via the Files.app appear in Recently Deleted, but those files are actually moved to the following directories: iCloud Drive /var/mobile/Library/Mobile Documents/.Trash/ On My iPad /var/mobile/Containers/Shared/AppGroup/{UUID}/File Provider Storage/.Trash/ App sandbox Documents directory ([On My iPad]/[Any App]) /var/mobile/Containers/Data/Application/{UUID}/Documents/.Trash/ When resolving the bookmark after deletion, the bookmark still resolves successfully and returns the new file URL inside the .Trash directory. I tried the following checks on the resolved URL: Checking file existence Checking read/write accessibility Inspecting bookmark resolution results Using APIs related to NSTrashDirectory See https://developer.apple.com/forums/thread/813329#813329021 All of these behaved the same as when the file was moved to a normal directory. None of these checks allowed me to detect that the file had been deleted. Additional experiment: I suspected that the app might simply check whether the path contains ".Trash", so I performed the following experiment. If a .numbers file is moved to /var/mobile/Containers/Data/Application/{UUID}/Documents/.Trash/ then The file appears in Recently Deleted in Files.app Numbers.app does not reopen the document when the app launches However, if the same file is moved to Documents/Trash Documents/.Trashed Documents/Any Folder/.Trash then The file does not appear in Recently Deleted in Files Numbers does reopen the document when launched This suggests that Numbers.app is not simply checking whether the path contains ".Trash".

I'd like to create a small helper app for new students do read/write User default settings. Since it was not possible using the UserDefaults class I decided to use the "/usr/bin/defaults". Unfortuntely it seems not to return anything. Debug output shows "Got data: 0 bytes" Here is a sample code: import SwiftUI func readDefaults(domain : String, key :String) -> String { let cmdPath = "/usr/bin/defaults" //let cmdPath = "/bin/ls" let cmd = Process() let pipe = Pipe() cmd.standardOutput = pipe cmd.standardError = pipe cmd.executableURL = URL(fileURLWithPath: cmdPath, isDirectory: false, relativeTo: nil) cmd.arguments = ["read", domain, key] //cmd.arguments = ["/", "/Library"] print("Shell command: \(cmdPath) \(cmd.arguments?.joined(separator: " ") ?? "")") var d : Data? do { try cmd.run() d = pipe.fileHandleForReading.readDataToEndOfFile() cmd.waitUntilExit() } catch let e as NSError { return "ERROR \(e.code): \(e.localizedDescription)" } catch { return "ERROR: call failed!" } // get pipe output and write is to stdout guard let d else { return "ERROR: Can't get pipe output from command!" } print("Got data: \(d)") if let s = String(data: d, encoding: String.Encoding.utf8) { print("Got result: \(s)") return s } else { return "ERROR: No output from pipe." } } struct ContentView: View { let foo = readDefaults(domain: "com.apple.Finder", key: "ShowHardDrivesOnDesktop") var body: some View { VStack { Text("ShowHardDrivesOnDesktop: \(foo.description)") } .padding() } } #Preview { ContentView() } This code works well e.g. for "ls" when the comments are changed for cmdPath and cmd.arguments. What do I miss in order to get it working with defaults?

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!

Hello, I am the developer of an app called one sec which helps users to spend less time on social media: https://one-sec.app Therefore, we make heavy use of the Screen Time API, and thus ManagedSettings and ShieldActionDelegate. One feature of one sec is the so-called “Doom Scroll Emergency Brake”. This blocks a target app after a certain usage threshold (e.g. 5 minutes) and requires going through an intervention (e.g. breathing exercise) to unlock more time. That added friction makes it very effective in reducing time spent on apps. One thing that is confusing for our users is the way they are prompted to unlock more time, if they want to. They have to: Have Push Notifications enabled for one sec Exempt one sec’s notifications from being delayed by AI prioritization (otherwise they are delayed by ca. 10s) Ensure that push notifications can be delivered during foci. Understand that they have to tap on the notification, which is not very straight-forward because it does not make sense from the user’s UX perspective. This is an artificial limitation of Apple’s screen time framework which has no reason (no security / privacy implications here…). Screenshots of the current flow attached. If would be much more reasonable if there was a new ShieldActionResponse.openParentApp value that can be returned from the completion handler of the ShieldActionDelegate.handle(…) callback. We have seen different apps use private API to achieve this, but we are afraid to do the same to avoid getting banned from the App Store. It would be fair if Apple would level the playground for all apps and offer such an API officially. – Frederik PS: Tracked under FB22347946, FB18846650, FB15500681, FB15079668, FB10393561 (all without responses so far…)

Hi community. It's my first time trying WatchConnectivity kit. When I attempt to send ApplicationContext from phone, my debug print indicates that updateApplicationContext is working correctly. However, I'm having trouble receiving it form the paired watch simulator as nothing is shown on that end. Here are the code for the Phone Extension:     func sendDataToWatch(data: String) {         state.append(data)         do {             NSLog("sent by phone")             try WCSession.default.updateApplicationContext(["currentstate": state])         }         catch {             print(error)         }     } Here are the code for watch: func session(_ session: WCSession, didReceiveApplicationContext applicationContext: [String: Any]) {         print("Hello")         if let getState = applicationContext["currentstate"] as? [String]{             print("\(getState)")             self.state = getState[0]         }     } Any suggestion would be appreciated!

From the Feb 24 news, I understand that for all Apple users in Brazil with iOS26.2 and newer, isEligibleForAgeFeatures will eventually return true. Brazil is a "nonregulated region", and developers will need to handle all three situations of ask first/always share/never share. Please correct me if I'm wrong above. A few questions follow on the eligibility check: What's the return value of IsEligibleForAgeFeatures for a Brazilian user who has NOT touched the age range feature at all, thus hasn't picked one of the three options? How can we test these cases? From the updated sandbox doc, there's more information on declined/approved, will those the same behaviors as a future Brazilian user? The doc used to say Texas, now it doesn't say any region. On which date will Apple START to return true for IsEligibleForAgeFeatures for Brazilian users? I cannot find the exact date anywhere. Will ALL of Brazil return true overnight, or is there some ramp up that developers need to be aware of? Thanks a lot for sharing the guidance, and thanks in advance for more guidance to come!

My scenario is to help users set up a full year's alarms at once. The dates for the alarms follow a specific pattern, but not fixed weekdays, so the fixed-date type is needed.

Is this intended behavior? I want my app to act like the regular Clock app and snooze alarms when user taps volume down button but apparently volume down button stops the alarm. Is this normal or am I missing something?

Hi. The WWDC video of the v2 weatherkit api showed some examples for the REST API. However, they were very limited. The documentation for the REST API is currently for the v1 weatherkit API. When will the documentation for the v2 API be released? There are some new features of the v2 that I would really like to use, but I can't without knowing the new v2 REST API specifications. Any guidance would be much appreciated. Thanks!

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?

We now know the IsEligibleForAgeFeatures API is NOT returning True in Brazil at least 2 days past compliance date, and we don't know if that's the right API, or how it behaves. Folks here: Is there anyone here from Brazil who has tested out this 26.4 API? Has anyone tested out the regulatory feature API? Does it return something like declaredAgeRangeRequired? I don't know how to test it in Brazil without sandbox/physically in Brazil. Much appreciated!!

Hello, I’m encountering an issue with Universal Links in my iOS app. After some investigation, I found that the root cause seems to be that Apple’s request through there CDN server to access the .well-known/apple-app-site-association file is blocked by our firewall, which enforces geographic access restrictions as part of our security policy. Because of this restriction, Apple’s validation or link verification requests are being denied, and the Universal Links are not working as expected. I’d like to get some guidance from the community or Apple engineers on the following: 1. Does Apple provide an official list of IP ranges or domains that need to be allowed through the firewall for Universal Link validation? 2. Are there alternative methods to handle Universal Link verification in environments with geographic restrictions? 3. Would whitelisting specific Apple services or endpoints be a recommended or safe solution? Any input or recommendations would be greatly appreciated. Environment Details: • iOS app using Universal Links • Server protected by a firewall with regional restrictions • AASA file hosted correctly and accessible via browser Thanks in advance for your help and insights.

I enabled the WeatherKit capability on my App ID (com.saimcan.darkweather, Team 6SWSD6V4ZC) about 12 hours ago. The entitlement is embedded in the binary and the provisioning profile authorizes it, but every request fails at the JWT generation step. Error from the logs: Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)" Relevant log excerpt (iOS 26.4 Simulator, same result on a physical device): [AuthService] Calling process is 3rd party process and has the correct entitlement ... accepting the connection [AuthService] Received proxy request for generating a jwt token. url=https://weatherkit.apple.com [WeatherDataService] Starting to generate JWT token request. bundleIdentifier=com.saimcan.darkweather [AuthService] Signed successfully [WeatherDataService] Make new JWT token request. requestIdentifier=...

The documentation for NSURL -URLByAppendingPathComponent: states: "Returns a new URL by appending a path component to the original URL." Path component is singular. But this "works" : NSURL *testURL = [applicationsDirectory URLByAppendingPathComponent:@"Evil/../../" isDirectory:YES]; So my questions are: One) Was it always this way? I can't recall if it was like this before the Foundation rewrite and I just never stumbled across? and Two) Is it intended behavior? The API seems to suggest that you append one path component on the url with this method. But I guess you can append as many as you want?

I try to update remoteHandle using CXCallUpdate for outgoing call, but this works only on iOS 15 but not on 17 or 18 (16 didn't test). This problem actual only for outgoing calls, but for incoming calls update works fine. func startOutgoingCall(with callID: UUID, userID: String) { let handle = CXHandle(type: .generic, value: userID) let action = CXStartCallAction(call: callID, handle: handle) callController.requestTransaction(with: action) { [weak self] error in // ... } } func updateOutgoingCall(with callID: UUID, groupID: String) { let update = CXCallUpdate() update.remoteHandle = CXHandle(type: .generic, value: groupID) provider.reportCall(with: callID, updated: update) } I also tried phoneNumber type but it seems initial handle that I set to CXStartCallAction not possible to change (value or even type). I use this handle value to implement recall by tap on call in Recents tab of system address book. But since my calls can transform from p2p to group call, I need to update handle value or find some another way to pass call identification info.

I'd like to set my macOS app written in Swift as default app when opening .mp4 file. I think I can do it with setDefaultApplication(at:toOpen:completion:). https://developer.apple.com/documentation/appkit/nsworkspace/3753002-setdefaultapplication However, permission error occurs when I use it. The error is: Error Domain=NSCocoaErrorDomain Code=256 "The file couldn’t be opened." UserInfo={NSUnderlyingError=0x6000031d0150 {Error Domain=NSOSStatusErrorDomain Code=-54 "permErr: permissions error (on file open)"}} I tried to give my app full-disk access, but it didn't work. I also tried to use setDefaultApplication(at:toOpenFileAt:completion:), then it works with no error, but it effects on only one file. What I want to do is to set my app as default app of all .mp4 files. How do I achieve this? My code is like below: let bundleUrl = Bundle.main.bundleURL NSWorkspace.shared.setDefaultApplication(at: bundleUrl, toOpen: .mpeg4Movie) { error in print(error) } Thank you.

Hi everyone. I've downloaded the the 26.2 beta 2 and installed it on a device in the settings after i create a new sandbox test account i see the options in Age Assurance. The problem is i got the popup the first time i opened the application and decided to share, but after that i always get the following error: DeclaredAgeRange.AgeRangeService.Error.notAvailable I tried testing with different bundle id and different sandbox test account but still it doesn't work. How can i test the cases without erasing the device ?

Certainly! Here's a concise version of your forum post: Title: Issues Handling Multiple Incoming Calls in CallKit Body: Hello, I'm using CallKit and I am encountering challenges with handling multiple incoming calls. Current Configuration: configuration.maximumCallsPerCallGroup = 5 configuration.maximumCallGroups = 3 This setup aims to allow up to 5 calls per group. Observed Behavior: Despite the configuration, the system UI seems to limit the number of calls per group, often defaulting to "End & Accept" instead of "Hold & Accept" when a third call comes in. Questions: Is there a documented system-imposed limit on the number of calls per group or total calls, even if maximumCallGroups and maximumCallsPerCallGroup are set higher? How does the system UI behave when these limits are exceeded? Are there known UI constraints or fallback behaviors? Are there best practices for handling scenarios where the system UI cannot display all calls, such as gracefully managing incoming calls or providing alternative UI solutions? Any insights or experiences with similar configurations would be greatly appreciated. Thank you. Feel free to copy and paste this directly into the Apple Developer Forums. If you need further assistance or adjustments, let me know!

I have an app developed by using the Callkit/Call-Blocking and received feedback from individual users, when using [cxcalldirectorymanager reloadextensionwithidentifier] to write call blocking data, it returned error code 11 with the following contents: errorCode: 11 errorDomain: com.apple.callkit.database.sqlite errorDescription: sqlite3_step for query 'DELETE FROM PhoneNumberBlockingEntry WHERE extension_id =?' returned 11 (11) errorMessage 'database disk image is malformed' I want to know the reasons for this error and how to solve it，Thanks!

When I call https://developer.apple.com/documentation/contactprovider/contactprovidermanager/enable() to request to use Contact Provider, I received a dialog with message like this "App Name would like to add its contacts as its own list. Contacts added this way can be removed from settings". I would like to support this message in Japanese or other languages. Is it possible?
