I am seeing a weird behavior of the date formatter (Full code is below). When run, this will give the following output: 57: 1 month, 3 weeks, 5 days 58: 1 month, 3 weeks, 6 days 59: 2 months 60: 2 months, 1 day 61: 2 months 62: 2 months, 1 day 63: 2 months, 2 days So both 59 days and 61 days are 2 months, and both 60 and 62 days are 2 months and 1 day. This of course is especially weird because this means, 2 months also comes after 2 months and a day. Can someone explain to me what is going on here? import Foundation let formatter = DateComponentsFormatter() formatter.unitsStyle = .full let calendar = Calendar(identifier: .gregorian) let today = calendar.date(from: DateComponents(year: 2025, month: 7, day: 26))! for day in 57...63 { let startDate = calendar.date(byAdding: .day, value: -day, to: today)! let components = calendar.dateComponents([.day, .weekOfMonth, .month,. year], from: startDate, to: today) let result = formatter.string(from: components)! print ("\(String(format: "%3d", day)): \(result)") }

Hello, we are experiencing an issue that is not systematic regarding universal links on our application. In some cases, after the application is installed, the universal links do not open the application but instead open in Safari. We have conducted tests on several devices and with the same link. In some cases, the links open the application after installation, and in other cases, they open in Safari. I should mention that in all test cases, we did not force the opening via the menu accessible through a long press on the link. We performed sysdiagnose in the different cases and we observed the same configuration for the universal links in the swcutil_show.txt file: User Approval: unspecified Site/Fmwk Approval: approved At this stage, I do not think the problem comes from our application or the configuration of the apple-app-site-association file. Is this a known issue? Is there anything we can do on our side to work around it ?

Hi, we are developing a screen time management app. The app locks the device after it was used for specified amount of time. After updating to iOS 26.2, we noticed a huge issue: the events started to fire (reach the threshold) in the DeviceActivityMonitorExtension prematurely, almost immediately after scheduling. The only solution we've found is to delete the app and reboot the device, but the effect is not lasting long and this does not always help. Before updating to iOS 26, events also used to sometimes fire prematurely, but rescheduling the event often helped. Now the rescheduling happens almost every second and the events keep reaching the threshold prematurely. Can you suggest any workarounds for this issue?

I have been trying to use TipKit popovers in my App. They all behave as expected in the simulator but on a real device I am seeing some strange behaviors. I have a couple of instances of where the tip is displaying an entire sheet instead of just the popover. In another case I cannot dismiss the Tip. Has anyone seen these behaviors and are there known issues/workarounds for this? I am reluctant to use something that works perfectly in the simulator but gives unpredictable results on a device. Not a good user experience in my opinion.

Do we need to take approval for any entitlement for the extension Unwanted Communication because currently I do not see my app in the Settings under SMS/Call Reporting extensions.

On iOS:When one receives a file of type .pages by email, Mail displays a large Pages icon and tapping on it opens Pages. (A long-press brings up the more complicated Actions screen).When one receives a file of type .vcf by email, Mail displays a large Contacts icon and tapping on it opens Contacts. (A long-press brings up the more complicated Actions screen).I have my own custom file type, .ripf, and I want to have the same behaviour because that is what my users will expect. Accordingly, in my app's Info.plist I have a CFBundleDocumentTypes dictionary providing a one-element LSItemContentTypes array referring to the name 'com.universalis.ripcard', and a UTExportedTypeDeclarations dictionary associating the UTTypeIdentifier 'com.universalis.ripcard' with a public.filename-extension 'ripf' and a public.mime-type 'text/vnd.universalis.ripcard'. All the other entries in those two dictionaries are present and correct as far as I can tell. Both CFBundleDocumentTypes[0].CFBundleTypeIconFiles and UTExportedTypeDeclarations[0].UTTypeIconFiles contain a list of icon files for the file type.(That rather long paragraph is to avoid boring people by including the entire Info.plist!)Some things do work..ripf files received via AirDrop bring up a suitable "Open with..." message which mentions my app, and tapping the message opens the app..ripf files received as an email attachment display as an icon. But it is the app's icon and not the icon of the file type.BUTTapping on a received file's icon does not open the app, but only opens the generic Actions screen, offering Message, Mail, WhatsApp, Notes, and only then (after the user has scrolled sideways) "Copy to..." my app.Now, the whole apparatus of CFBundleDocumentTypes and UTExportedTypeDeclarations is obscure and under-documented, and indeed the main documenation for the latter has a big warning at the top saying that it is obsolete and not being updated. That doesn't matter so much. What I need to know is:(Less important): How do I get the right file icon?(More important): How do I get my app to open when the icon is tapped, as Pages and Contacts do? There must be a way – unless special cases for those two apps are wired into iOS itself.

Hi There, hopefully someone can help me here, we weren’t aware but our universal links stopped working sometime last year, as they are not used often on the apps, it wasn’t noticed. We checked all the elements and this is the situation: Our apple-app-site-association file is located at https://ourdomain.com.au/.well-known/apple-app-site-association And it is accessible and can be downloaded. We have Associated Domain services enabled for our app Bundle Id: au.com.identifier.app The Entitlements.plist in our app contains the list of associated domains - the second is the full url, the portal won't let me write it as such as it's not the real address. But links for the first two, …ourdomain.com.au domains don’t work Request https://ourdomain.com.au/.well-known/apple-app-site-association downloads the file and returns status code:403 While checking the availability with https://app-site-association.cdn-apple.com/a/v1/ourdomain.com.au we get the error: ourdomain.com.au: Failed to load resource: the server responded with a status of 404 (Not Found) Going directly to the hosted website: https://app-site-association.cdn-apple.com/a/v1/ourdomain-prod-ourdomainwebsite.azurewebsites.net Returns the json: { "activitycontinuation": { "apps": [ "99ABCD88XXX.au.com.identifier.app", "99ABCD88XXX.au.com.identifier.server.adhoc", "99ABCD88XXX.au.com.identifier.server.dev" ] }, "applinks": { "apps": [], "details": [ { "appID": "99ABCD88XXX.au.com.identifier.app", "paths": [ "/m/" ] }, { "appID": "99ABCD88XXX.au.com.identifier.server.adhoc", "paths": [ "/mt/" ] }, { "appID": "99ABCD88XXX.au.com.identifier.server.dev", "paths": [ "/md/*" ] } ] } } It appears to be something in the redirect from the url but debugging shows nothing obvious. Has anyone experienced this before? Thanks

Hi All, I am facing one problem in my app. That is open battery settings from my app. It is working fine in iOS 16.0.0 and it's not working in iOS 18.6.1 is it possible to make it workable in iOS 18.6.1? If so How to do that? Please help me over this to resolve the problem. Thanks, Nguyen Quang Minh

I have also tested this on iOS 26 (Beta 9 and above), and the CallKit call blocking functionality is not working. Numbers that should be blocked still ring through. Caller Identification continues to function as expected, but blocking entries (addBlockingEntry) are ignored.

I am trying to set up a message filter extension that will use shared web credentials for basic auth when calling to its ILMessageFilterExtensionNetworkURL. I have associated domains set up for both "messagefilter:" and "webcredentials:" and the message filter IS correctly calling the ILMessageFilterExtensionNetworkURL with each message - so that part is working. As detailed here, I have set up Shared Web Credentials and my view controller is using SecAddSharedWebCredential() to save the creds to the correct domain. Using Authorization services, the creds are auto-filled into my app's login screen. When I go under Settings > Passwords, I see the creds are saved and they are the correct creds to the corrent website that matches ILMessageFilterExtensionNetworkURL. Regardless of all of this, the deferQueryRequestToNetwork() refuses to use the creds and implement Basic Auth in its URL call. It makes the call to the correct URL, it just won't use the Shared Web Creds for basic auth. Any help would be greatly appreciated.

I get several warnings in log: *** -[NSKeyedUnarchiver validateAllowedClass:forKey:] allowed unarchiving safe plist type ''NSNumber' (0x204cdbeb8) [/System/Library/Frameworks/Foundation.framework]' for key 'NS.objects', even though it was not explicitly included in the client allowed classes set: '{( "'NSArray' (0x204cd5598) [/System/Library/Frameworks/CoreFoundation.framework]" )}'. This will be disallowed in the future. I am not sure how to understand it: I have removed every NSNumber.self in the allowed lists for decode. To no avail, still get the avalanche of warnings. What is the key NS.objects about ? What may allowed classes set: '{( "'NSArray' be referring to ? An inclusion of NSArray.self in a list for decode ? The type of a property in a class ?

Issue After upgrading to Tahoe 26.2, print queues monitored by PaperCut no longer work. The print queue gets paused, and the jobs fail to print. This issue was discovered during our internal testing prior to the Tahoe 26.2 public release, and a growing number of our mutual customers have also reported it since then. Root cause This appears to be due to changes in the behavior of CUPS Sandbox restrictions, which prevent the backend (and filter) from reading/writing to the PaperCut install folder. Error messages From syslog. 2025-12-22 16:41:59.283761+1100 0x1daf61 Error 0x0 0 0 kernel: (Sandbox) Sandbox: papercut(5783) deny(1) file-write-data /Library/Printers/PaperCut/Print Provider/print-provider.log When trying to create a TCP socket from the PaperCut filter. 2025-12-15 19:50:08,403 ERROR: os_tcp_socket_create: getaddrinfo failed: nodename nor servname provided, or not known Technical details PaperCut implements print queue monitoring using a CUPS backend (and filter). CUPS backends and filters run in a security 'sandbox' which limits what they can do (such as file/folder access, create network sockets, and execute sub-processes, etc.). The PaperCut backend (and filter) relies on some of these operations, so to function correctly, our code updates /etc/cups/cups-files.conf with "Sandboxing relaxed". Until 26.2, this relaxed mode allowed us to read/write to PaperCut folders, create TCP sockets to communicate with the local PaperCut Application Server, and execute/kill sub-processes. As an alternative to the relaxed mode, we also tried "Sandboxing off", but that doesn't help either (from CUPS scheduler/conf.h). typedef enum { CUPSD_SANDBOXING_OFF, /* No sandboxing */ CUPSD_SANDBOXING_RELAXED, /* Relaxed sandboxing */ CUPSD_SANDBOXING_STRICT /* Strict sandboxing */ } cupsd_sandboxing_t; Test code We can provide a simplified version of our backend that demonstrates the issue if required Questions Has the CUPS sandbox relaxing changed? According to the CUPS man pages (cups-files.conf(5)), "Sandboxing relaxed" should still work as before. If this is the new intended behavior, what are the other options/directives we can use to relax the limitations on CUPS backends and filters?

A screen time app I'm making has started telling users that their limit was reached even when they're far below their limit for the day (sometimes even at 0 minutes for the day). This issue only started happening after upgrading my software to iOS 26.2. Is this happening to anyone else? If so how have you found any solutions or does anyone know of any changes that could be causing this? Any help would be appreciated.

Hello, I have an app that emulates an NFC card using NFC HCE. Since yesterday I saw an increasing number of crashes on iOS 26 only, which wasn't there before. From what I can see, it seems the app crashes when the NFC presentment intent is shown and 60 seconds passed and user does nothing. The app just crashes after 60 seconds. On previous iOS versions, I know that CardSession.Error.maxSessionDurationReached was thrown after 60 seconds. Is something changed in iOS 26?

In iOS 18 (beta 1-4) when you set openAppWhenRun = false in your AppIntent of your live activity the perform function never gets called. In iOS 16 and 17 my live activities work. I have downloaded other apps and in their live activities any button tab which doesn´t open the app is also doing nothing in iOS 18. Has anyone got this working? Any comments from an Apple engineer on this?

When selecting a stroke path for object on PKCanvas, the option "Snap to Shape" appears. I understand this function is still in beta and has not made available natively to other PencilKit app. Is there a way using Stroke API to call this function directly after the user hold pencil for half a second when stroke is done drawing, just like how it behaves in native apps?

I am trying to send an anonymous XPC listener endpoint to my daemon from user context in order to be able to do some bidirectional XPC. I was trying to use the new XPCListener and XPCSession objects and the easiest method I figured was using the Codable version of the send() methods, in which I wanted to send the XPCEndpoint object - alongside the name of the anonymous endpoint (because I want to have more XPCEndpoints sent over, so I want to be able to identify them. However, trying to manually encode XPCEndpoint throws an exception: ERROR: Missing CodingUserInfoKey CodingUserInfoKey(rawValue: "_XPCCodable") Here is a simple command-line tool reproducing the issue: import Foundation import XPC let listener = try XPCListener(service: "mach-service.xxx.yyy", incomingSessionHandler: { $0.accept(incomingMessageHandler: { (msg: XPCReceivedMessage) in return nil }) }) var endpoint = listener.endpoint do { let endpointData = try JSONEncoder().encode(endpoint) print("EndpointData object: \(endpointData.count) bytes") } catch let error { print("ERROR: \(error)") } Wrapping my object into an XPCDictionary, then adding multiple keys alongside an "endpoint" key with the XPCEndpoint as value works, but XPCDictionaries are less ideal - they don't even support vanilla Data objects, only ones converted to an xpc_object_t with xpc_data_* functions Is this expected behavior? I shouldn't encode an XPCEndpoint myself? I am using the latest Xcode 26.0 beta, with deployment target of macOS 15.1, running on macOS 15.5. (Btw it's also incorrect that this XPCEndpoint API is available from macOS 15.0 - it cannot be found in Xcode 15.4 under macOS 15.5. At the very best it's backDeployed but this isn't mentioned in its public declaration.)

We are planning to use our internal IdP (PingFederate) for authentication of end users in their iOS apps using ASWebAuthenticationSession. Initial tests are successful, but the user is prompted for every login (and logouts) with a consent dialogue box: “AppName” wants to use “internal domain-name” to Sign In This allows the app and website to share information about you. Cancel Continue” Let’s say that our top-level domain is “company.no”, where our IdP is placed at “idp.company.com”. I have seen examples where the Associated domains entitlement points to the idp as a webserver for serving the JSON output AASA file. In this case that would be: authsrv: idp.company.com Anyone with experience implementing this structure with the IdP as webserver for serving the JSON output? Our problem is that trying to use the IdP as webserver for this purpose is that it is very complicated to modify the IdP’s webserver configuration. Also, this modification needs to be re-done every time we need to upgrade the IdP. My question is therefore also related to the options of which webserver to install the AASA file on. Has anyone installed the file on a generic webserver on the toplevel domain like “webserver.company.com” ?

We recently released an update to our app to prepare for TX SB2420. Almost immediately on release, we started getting crash reports of crashes when calling isEligibleForAgeFeatures. Crashed: com.apple.root.user-initiated-qos.cooperative EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000004 Is it possible that these are beta users that have IOS 26.2 RC or is there a bug in the release version of IOS 26.2? Note: The crash reports are coming from Crashlytics so we are not getting OS build identifiers other than version "26.2"

I'm reading the "Testing Age Assurance in Sandbox" doc, but I couldn't figure out the step: 2. Tap Sandbox Testing from the main menu Where is the "main menu"?
