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

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.

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

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,

Reply to Passkit generator vulnerabilities issue
Hi @ashishvani, You wrote: We are getting vulnerabilities for passkit generator, used for apple wallet creation. Both @dapeters and @AlexanderCerutti are correct, passkit-generator is a third-party library and is not provided, nor supported, by Apple. However, if you'd like to use our new Pass Designer and Pass Builder tools to manage your Wallet pass creation, signing, and personalization, please see the following WWDC26 session: WWDC26: Session 209 – What's New in Wallet https://developer.apple.com/videos/play/wwdc2026/209/ Cheers, Paris X Pinkney |  WWDR | DTS Engineer

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?

How to delete campaign group?
I have created a campaign group and then realized that was not what I meant — I was hoping I could add existing campaigns to a group and use this group to view only those campaigns in my dashboard. How do I go about deleting this empty campaign group and is there a way to achieve what I'd intended? TIA.

Reply to Invalid code signing entitlements with app group on macOS
To whom it may concern and help: Summary: If you have macOS Apps and use App Groups and want to distribute to the App Store, do yourself a favour and upgrade your macOS to Sequoia and Xcode to at least 16.3. Detail: I had no issues with app groups for macOS apps until after mid Feb 25. I used Xcode 15.2 on a Ventura iMac. Then, as per posts above, it all failed upon distribution. I also saw two AppGroup capabilities in Signing&Capability. I tried everything I read here and more. Registered the app group (although it is not necessary for a macOS app), included in Build Settings the 'Register App Group' trick from Eskimo (but it is for iOS App Groups), tried to monitor what is going on with my provisioning profile (but dump on exported app does not work as macOS apps do not embed a provisioning profile I think), deleted all provisioning profiles, created my own manually etc etc. Nothing worked. Upgrading to Sequoia and Xcode 16.3 does it without any pain

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?

Difference between memory numbers on Summary tab vs Memory tab.
Hello, I have noticed when taking a GPU Capture on IOS that the texture memory numbers seen on the Summary Page is much higher than what I see when viewing the Memory tab. I have also found that when totaling the allocated size of all the textures in the Memory tab, it equals the numbers seen on the Summary page, but not in the Memory tab itself. I am curious as to which numbers I should be trusting when using this tool.

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.

Can we get both refund and sales data from Summary Sales Report?
I'm wondering how the data in Summary Sales report is aggregated. Does Apple aggregate refunds and sales together?Say, if a specific product have 2 sales and 1 refunds, and the price is $5. Will the corresponding report have 1 row saying 1 sale for $5 or have 2 rows saying 2 sales for $5 each and 1 refund for -$5?
