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 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

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

Thursday iTunes Connect Lab Notes
Question:Since in-app purchases still cannot be managed by MDM, how does Apple plan to address managing applications that may move to a subscription model?Follow up: What is Apple's recommended approach for managing free applications with in app purchases? Device based assigned apps cannot purchase any in app purchases.Answer:In-app purchases are tied to a customer's Apple ID, rather than the VPP-purchased app. The challenge is finding a way to have that purchase be tied back to the original VPP-purchased license which was device-assigned.Apple has not yet found a good way to associate the in-app purchase back to that VPP-purchased license. They're aware of the issue and are working on it, but no solution is yet available.Subscriptions have a similar issue, since the subscription may be renewed or not renewed. The price of the subscription may also change. Apple is also working on this issue, but no solution is yet available.File bugs on this issue.See complete list of session and lab notes here:http

Subscription Summary not appearing in App Store Connect
This week I released an app with an IAP and subscription in. Whilst I'd be stunned if anyone had subscribed, I'd like to at least confirm that. However, in App Store Connect, apparently I should have a Subscription Summary according to this article here: https://developer.apple.com/help/app-store-connect/view-sales-and-trends/view-subscription-data But I don't have one: Is there any criteria you have to hit to see the subscriptions?

LLVM Debugger shows "Summary Unavailable" for complex c++ structs
I'm using the GLM http://glm.g-truc.net/0.9.8/index.htmlmath library for an opengl game in c++. Xcode's LLVM debugger simply will not reliably show summaries of the basic data types (glm::dvec2, glm::dmat4, etc). Instead, I get Summary Unavailable and when I click the disclosure triangle next to the data item, nothing is revealed. If I use the LLVM repl, e.g., I type e some_vec I get output like: (glm::dvec2) $0 = {} - which is not helpful.I've tried setting custom summary formats.~/Library/Developer/Xcode/UserData/Debugger/CustomDataFormatters <SummaryFormatter formatString = ({$VAR.x},{$VAR.y}) type = glm::dvec2> </SummaryFormatter>No luck!Any suggestions?Thanks,

Apple Vision Pro developer labs sign-up
I (think) I just signed up for the Apple Vision Pro developer labs - but am not sure if it went as intended. After submitting my screenshots - I was pushed to a screen prompting me to sign-out of my Apple account. No indication I successfully submitted a request / no email. Has that been other people's experience?

Notes from Thursday Education and Enterprise Development Lab
Question:What does opendirectoryd's FDESupport module do?Answer:That's the module which is responsible for taking password updates from opendirectoryd and updating the FV 2 pre-boot login password. It's a helper utility.Question:Does fdesetup sync also help sync passwords from a directory service?Answer:No, it does not sync passwords. (Same message from both Security and Enterprise labs.)Question:Is there a way to run a deferred enablement, which also allows the enablement of a second account. For the purposes of the question, assume that the second account's password has been provided.Use cases that may apply:A. An enterprise that wants deferred enablement for the primary user of the machine, but also wants to enable the local admin account for FV 2.Answer:Please file enhancement requests. (Same message from both Security and Enterprise labs.)Question:When using fdesetup enable -inputplist the password is clear text in the plist. Can this be changed so that the password can be hashed?

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.

Reply to How to get on the front page of the visionOS App Store?
I'm curious, why don't you book a WWDC lab for that question and other related ones you may have? Perhaps App Store business and marketing consultation is the lab you're looking for.
