Apple health data retrieval issue with summary
In Apple health I have the data for current day & my Application also connected with Apple Health. I gave all permissions regarding the health records. Some of the user the summary query is not getting executed & no data returned from the query. Most of the users are working fine. Background fetch is also enabled for Apple Health. The user is trying to sync the data in foreground. In crashlytics I got the error Protected health data is inaccessible. Can you please help me when this error may come.

Possible typo in concurrency diagram (WWDC25: Elevate an app with Swift concurrency)
Hello, While watching WWDC25: Code-along: Elevate an app with Swift concurrency at timestamp 25:48, I noticed something in the slide/diagram that might be incorrect. The diagram shows ExtractSticker twice, but based on the code context and spoken explanation, I think it was meant to be ExtractSticker and ExtractColor. Reasoning: The surrounding code and narration describe the use of async let and a Sendable Data object. From the flow, one task extracts a sticker while the other extracts a color, so it seems like the diagram is inconsistent. I do understand that with @concurrent, having two ExtractSticker operations on the same Data is technically possible (with two concurrent process executing their respective ExtractSticker) — but that would be a different meaning than what the talk was describing. Since concurrency is already a subtle and error-prone topic, I thought it was worth pointing this out. If I’m mistaken, I’d love clarification. Otherwise, this could be a small correction to keep things a

Vision Pro Developer Lab registration rejected, but why?
After a few days of excitement waiting, I was very disappointed to receive the reply email without any explanation. Your registration request for Apple Vision Pro Developer Lab has not been approved at the moment. I saw on the internet that some people can pass the application just by taking screenshots of downloaded sample codes, while my serious developed application was rejected. Could someone please tell me the criteria for judging?

Summary of '27 Changes?
There doesn't seem to be a What's New in Networking or What's New in Foundation talk this year, and nothing mentioned in the various Release Notes, so can you summarize the overall changes across platforms, or point to a document that does so?

Reply to NavigationView scrolling broken when using TabView
Ok, changed it to struct ContentView: View { var body: some View { TabView{ Group{ List{ Text(Item 1) Text(Item 2) Text(Item 3) } } .tabItem { Image(systemName: list.dash) Text(Transactions) } Group{ List{ Text(Item 11) Text(Item 12) Text(Item 13) } } .tabItem { Image(systemName: list.dash) Text(Summary) } }.navigationTitle(Transactions) .navigationBarBackButtonHidden(true) } } and now it looks better but after switching to the other tab and back, its broken again (see clip below) https://imgur.com/a/BfiofU1

Filesystem Lab notes
Question: On Yosemite, there is an issue where FileVault 2 will report Encrypted Paused during the encryption process, then never resume. It won't decrypt, and the only fix seemed to be deleting the CoreStorage volume.Is there a fix for this besides deleting the CoreStorage volume? For example, how to unpause and either resume encryption or decrypt?Answer:The Encryption Paused issue was addressed in 10.10.3. The root cause was a problem with resizing the CoreStorage volume. When the CoreStorage volume was unable to grow, the encryption was paused and could not resume until the resize issue was addressed.To fix this issue:1. Update your Mac to 10.10.3, or boot from an alternate drive which is running 10.10.3.2. Un-lock the encrypted drive if necessary3. Open Terminal4. Run the following command to get your Mac's disk identifier:diskutil list5. Once you have the disk identifier information, run the following command:sudo fsck_cs -y disk_identifier_goes_here6. fsck_cs should repair the CoreStorage volume and add

For those who attended Vison Pro Dveloper Lab, how was it and how does it work?
My team is planning on applying for Developer Lab in Tokyo for September sessions, and I would very much appreciate the advice! How long does it take for Apple to give the approval/acceptance after applying for the session? How much time am I allowed for each sessions? it says the Developer Lab sessions will be held from 10 AM to 5 PM, does that mean I get to test my app using the Vision Pro during the entire period? How does the session usually take place? I got the impression that someone from Apple will be assigned to guide and assist me during the session, is this true? Also how many teams are allowed to visit in each sessions? If anyone know anything, please let me know because I am clueless.

Reply to Distributing a command-line binary executable?
Of course not, But I assume unsafe executables would be covered by the institution's code-of-conduct (similar to weight room, machine shop, chem lab, bio-hazzard lab, etc. rules). In any case, many schools periodically wipe all their lab and library computers.

Reply to SwiftData migration error: NSCloudKitMirroringDelegate are not reusable
Sadly there is not much change in SwiftData in WWDC25 while fatal issues like this one must be fixed as soon as possible. Just to allow SwiftData works normally.

how to get system scheduled summary settings in iOS 15
Hi, My App has some work to guide users to allow notification authorization pop-ups. But now in iOS 15, according to different settings, the system will pop up two different styles of pop-ups. So, I wonder if there is a way for me to get scheduled summary setting before I request notification authorization.
