Reply to Phone unlock/lock detection
First off, a clarification here: When the phone is locked, then WhatsApp routes calls through Apple’s native CallKit. When unlocked, pressing accept essentially redirects to WhatsApp, and then WhatsApp handles the call from there. Are you sure this isn't the standard CallKit flow? Have you tested this with Speakerbox? It's possible I'm misunderstanding, but what you're describing sounds like how CallKit works by default. More specifically, accepting a call on an unlocked device opens the target app (as well as starting the call), and most apps present their own call UI when this open happens. Keep in mind that you can't actually implement a good call experience without using CallKit. For example, without CallKit, any other incoming call from any other app will immediately interrupt your call, effectively hanging up your current call. Note that this is not a theoretical problem but is in fact the primary developer complaint that led us to create CallKit. The problem is that if the phone has been recen

Guideline 1.4.1 - Safety - Physical Harm
Hello everyone The application we developed is for pet medical care and is aimed at veterinarians The main function of the app is an AI conversation app, where the user talks to the AI. The AI answer content may involve disease diagnosis and treatment suggestions for pets. When we submitted it to the apple store for review, we received a 1.4.1 rejection notice (the app must clearly disclose data and methods to support accuracy claims related to health measurements) Our solutions Before entering the app, we have added a pop-up window (the pop-up window introduces that the output content of our app is generated by AI and cannot replace the malicious veterinary consultation and diagnosis. If you have health problems, please consult offline certified veterinarians and other content to ensure the safety of pets in a timely manner). Users must agree before proceeding to the next step of using the app. Our AI model has been registered with the algorithm (and we have also uploaded screenshots of the

[quote='856443022, DTS Engineer, /thread/797469?answerId=856443022#856443022'] No, I'm talking about withoutImplicitStartAccessing. We explicitly say it does not apply to security-scoped bookmarks: [/quote] This option causes an implicit call to startAccessingSecurityScopedResource() on the returned URL when it’s ready to use the resource. The way this is written makes it sound like there will be a call to startAccessingSecurityScopedResource somewhere, so that a subsequent pair of explicit startAccessingSecurityScopedResource and stopAccessingSecurityScopedResource will still leave access at 1, leaking kernel resources. It his not the case? Is this consistent across macOS and iOS? This option isn’t applicable to security-scoped bookmarks. The documentation phrasing isn't clear about whether it's talking about NSURLBookmarkResolutionWithSecurityScope specifically (which is only available on macOS), or if it also applies to iOS (where all bookmarks are security scoped AFAIU from your earlier messages)

Reply to Are read-only filesystems currently supported by FSKit?
Are read-only filesystems currently supported by FSKit? I think the tricky part here is what support here actually means. Let me start by what this actually does: pass the -r or -o rdonly options to the mount(8) command. Passing that to mount should mean that the VFS layer itself is prevented from writing to the device. In FSKit terms, that means FSBlockDeviceResource.writable should be false and that all write methods should fail. If either of those behave differently, then that's a HUGE bug that we'd need to fix ASAP. However, the confusing point here is that mounting a volume readonly doesn't necessarily define/change how the file system presents itself to the higher level system. That is, strictly speaking, nothing prevents a volume being mounted readonly... but that file system itself allowing itself to be fully modifiable. That might sound a bit strange, but as a concrete example, you could implement a resettable file system by using the on-disk file system as the starting structure, routing al

Swift Playground preview issues
I am a high school teacher from China, currently teaching programming courses at my school. Several issues are preventing the course from being completed on schedule. As shown in the image, there are two problems: The preview issue has existed since updating to the latest software and system version; I don't know how to resolve it. After renaming a Swift file, this window keeps popping up, even after closing it. This problem didn't exist last year. How can I fix this? Thank you for your reply! 我是一名来自中国的高中教师,目前在学校开设编程课程,目前有几个问题导致课程无法如期完成。如图所示,存在两个问题: 一、自从更新了最新版本的软件和系统后,预览问题就存在,不知该如何处理 二、swift文件重命名后,一直跳出来这个窗口,关掉以后还是跳出来 去年的时候还没有存在这样的问题,请问我该如何处理,感谢您的回复!

iOS BGProcessingTask + Background Upload Not Executing Reliably on TestFlight (Works in Debug)
iOS BGProcessingTask + Background Upload Not Executing Reliably on TestFlight (Works in Debug) Description: We are facing an issue with BGTaskScheduler and BGProcessingTask when trying to perform a background audio-upload flow on iOS. The behavior is inconsistent between Debug builds and TestFlight (Release) builds. Summary of the Problem Our application records long audio files (up to 1 hour) and triggers a background upload using: BGTaskScheduler BGProcessingTaskRequest Background URLSession (background with identifier) URLSession background upload task + AppDelegate.handleEventsForBackgroundURLSession In Debug mode (Xcode → Run on device), everything works as expected: BGProcessingTask executes handleEventsForBackgroundURLSession fires Background URLSession continues uploads reliably Long audio files successfully upload even when the app is in background or terminated However, in TestFlight / Release mode, the system does not reliably launch the BGProcessingTask or Background URL

Reply to AlarmKit play sound only once
Thank you for your post. When you do not provide your file to play, and you provide the default sound with sound: AlertConfiguration.AlertSound = .default, the sound will now be the default sound.he sound looping until you stop at what time? https://developer.apple.com/documentation/alarmkit/alarmmanager/alarmconfiguration/timer(duration:attributes:stopintent:secondaryintent:sound:) Do you have the time in a focused project with the sound file you are using to share it for people to give you ideas? If you're not familiar with preparing a test project, take a look at Creating a test project. Albert Pascual

Reply to iOS 26.1 PHPickerConfiguration.preselectedAssetIdentifiers doesn't select previous pictures in the PHPickerViewController
This sounds like a regression. Have you tried verifying if the identifiers are still valid when you try to use them again? You can do this by retrieving the assets using the identifier with the fetchAssets(withLocalIdentifiers:options:) method. See the article on Fetching Assets for more details. If the identifiers are valid and you’re still encountering the issue, please file a bug report. Include a minimal reproducible sample code and share the Feedback ID here so I can pass it on to the appropriate engineering team.

AlarmKit play sound only once
Hey, I successfully set my app to use alarm kit, alarm is showing up and everything, but I noticed that the sound I created (mp3 files, less than 30 sec each) only plays once, does not repeat itself. Is that intended?

Reply to AlarmKit play sound only once
So the default sounds plays over a minute on loop, while my sounds stop after 27-ish (less than 30). I waited another minute to see if my sound would be repeated but nope. I plan to put the app on github as open sourced soon, does that count as test project?
