Does UITableViewAutomaticDimension work with grouped UITableView ?
I have a UITableViewController created in storyboard and I have set the tableView to display in grouped mode.I am trying to use TableView's automatic cell height calculation by setting self.tableView.rowHeight = UITableViewAutomaticDimension; self.tableView.estimatedRowHeight = 50;and I am not overriding heightForRowAtIndexPath.The cells I am using are either Basic or subtitlte type (i.e no custom cells) and I have enabled multiline text for titleLabel and subtitleLabelby setting numberOfLines to 0However, the cell always display with height = 50 and it appears that the text labels are extending above and below the contentView to accomodate the multiline text.Things work perfectly well if I simply make the tableView to display in plain mode intead of grouped.So my question is 0 Does UITableViewAutomaticDimension work with grouped UITableView ?

Consumable ticket sharing within groups
Hello, I would like to ask for your opinion on whether the following in-app purchase (IAP) specifications would comply with the App Store Review Guidelines. ■ App Overview ・The app allows users to create a “Family Group” by inviting other family members to join. ・The app provides brain-training games. The game itself is displayed via WebView. ・All purchases use in-app purchase (IAP) only. No external payments or links are provided. ■ Purchase Types (2 models) ① Group Unlimited Plan ・If one member of a family group purchases this plan, all members of the same group can play the games without limits for a certain period. ・This is based on the app’s own group-sharing mechanism, not Apple’s “Family Sharing.” We will clearly state this in the UI to avoid confusion. ② Ticket System (Consumable) ・One user in the group purchases game-play tickets. ・Other members of the same group can also consume those tickets to play. ・Tickets are only shared and consume

Developer tools group?
I'm taking my first steps in learning to code in C (using the books 'C programming Absolute Beginner's Guide (Perry + Miller)', and 'Programming in C (Kochan)') . I'm about 2/3 + 1/3 of the way through the books. Last week, using X-code 7.3's IDE, I was able to build and run the programmes I typed in, and the answers came out correct. Then on Saturday, I created a programme that built and ran but gave the result 0.0000. So I tried using the break arrows, but didn’t understand the explanations about threads. So I searched for a button that would allow me to step through the programme one instruction at a time whilst I observed the changing values of the variables and the inputs to them. I pressed a lot of buttons, but could find it.Since then I’ve been unable to run any programme. (Did I unwittingly give a stop instruction to the IDE ?)The build is successful, and then a pop-up appears saying - Developer Tools Access needs to take control off another process for debugging to continue.

Adding subscriptions to group. Inactive state?
I currently have one subscription group with one approved subscription. It is live in production. I am now adding more subscriptions to the same group. Different tiers and different durations. Is there a way to get these new subscriptions approved by Apple, but not yet have them show as options within the group? Sort of an approved-but-inactive state? There's a timing issue. I don't want the new options to show before the website/app descriptive text supports them. And I don't want the website/app descriptive text to describe purchase options that aren't yet available.

Reply to Please provide bounds for ViewAttachmentComponent
Thanks both of you. Now I got more idea why this wasn't working when I showed it to Sydney in the labs, but also, Allan from RealityKit got me covered in the next Lab by pointing at the new SpatialContainer.

Reply to How to cast shadow on OcclusionMaterial in visionOS
There is a way to do this, but you will need to create a simple Shader Graph material instead of using the default OcclusionMaterial. There is a second version of this node called ShadowReceivingOcclusionSurface I didn't test this with Grounding Shadows, but it works with regular dynamic light shadows. You can find my notes on this from last year. https://stepinto.vision/labs/lab-026-using-dynamic-lights-and-shadows-with-passthrough/

Summary of issues encountered with the Screen Time interface
I have developed three apps using the Screen Time API. The following are common problems I encountered in the three apps: DeviceActivityMonitorExtension is automatically killed after running for a few days (frequently) The same DeviceActivityEvent in DeviceActivityMonitorExtension is triggered twice during eventDidReachThreshold (especially obvious in iOS18.5) Screen Time authorization is automatically canceled for no reason (occasionally) I hope to get help

Subscription Group Remains as Prepare for Submission
I'm ready to submit a new app with 3 subscription plans. But the status of the group remains 'Prepare for Submission.' And it won't change. All the individual subscription plans have the 'Ready to Submit' status. I have triple-checked individual plans to see if there is anything missing. No. Nothing is missing. There are no pending business contracts to review, either. I have even deleted an existing group and created a whole new subscription group. And I still end up with this prepare status. Am I the only one having this subscription group difficulty? One thing that I realize is that the status appears as 'Ready to Submit' on individual subscription plans. But their respective localization pair of display name and description get the Prepared status. The display name and the description fields are both filled for all three plans. What a nice, merry, merry Christmas. I don't know what else I can do to resolve this Prepared madness. I've been stuck for 4 hours.

SIMD-group shuffle on iOS?
It seems like the SIMD-group shuffle instructions (e.g. simd_shuffle(), simd_shuffle_down(), simd_shuffle_xor() etc. – subsection 5.13) aren't supported on iOS (#include <metal_simdgroup> throws an error).I'd like to know why aren't these instructions available on iOS – is it because the GPU architectures don't allow for these instructions to be implemented (why?), or is there any other reason?Furthermore is there a plan to add these instructions to iOS?

Summary of new requirements for IOS app submission
I'm looking for a comprehensive overview of the new requirements that Apple has enacted recently. I understand one new requirement is that the apps be built with XCode 12. Of course that many not even be correct, I just heard that somewhere. Any help finding the official word on this would be greatly appreciated.
