I have had success with the following native implementation from SwiftUI Lab: https://gist.github.com/swiftui-lab/3de557a513fbdb2d8fced41e40347e01 A few modifications had to be made including changes to use the new ProgressView etc.

CoreData and Group By
Hi Folks, Sorry I am sure this has been asked before - Beginner level programmer trying to get my head round something I am sure is simple. I know coredata is not a Relational database but please go easy!! I have data my app is storing as people respond to the 'game' a 'session' guid (runNumber) , and if they hit the correct button or not (correctAnswer). I want to group the responses by the guid and sum the 'correct' answers. I think I am pulling the data correctly: @Environment(.managedObjectContext) private var viewContext @FetchRequest( entity: CoreScore.entity(), sortDescriptors: [ NSSortDescriptor(keyPath: CoreScore.runNumber, ascending: false) ] ) var corescores: FetchedResults But my view List(corescores, id: .self) { corescore in Text(corescore.runNumber ?? Unknown) Text(corescore.correctAnswer ?? Unknown) } Shows all the individual responses... How do I group them by runNumber?

Reply to SwiftData 'simple' migration failing
I'd need to look into the code then. Is it possible that you provide a minimal project with detailed steps that demonstrates the issue? I've been pretty swamped as WWDC26 is right around the corner, but should be able to look into that after the conference, if not earlier. Best, —— Ziqiao Chen  Worldwide Developer Relations.

Cannot remove testing group from build/Groups auto adding to build
Hi, I would like to rollout our builds to a subset of our internal testers (the devs) before we roll it out to the rest (QA, product managers). After submitting the compliance on a build, both of my internal testing groups are automatically added to the build. I thought I would get to choose which group at add myself. To make matters worse, there doesn't appear to be any way to remove a testing group from a build, despite what the documentation says: As you can see, my pointer is over the group, but no Delete button exists Help! -Ethan

Group Apps
Since I have upgraded to IOS 14.2 on my iphone7. On several occasions I have found that I am unable to open my apps that I have grouped together. When I touch the screen the apps acknowledge that I selected it but it does nothing after that.

Wednesday Security Lab Notes
Question:In the session yesterday, it was mentioned that Gatekeeper's app relocation moved the app on an unsigned disk image to a randomized place on the filesystem. How does this work?Answer:When the app with the unsigned dependencies is launched, Gatekeeper makes a synthetic instance of the app at a randomized location elsewhere in the filesystem. The synthesized instance of the app is what is actually being launched.The synthesized instance is by itself in this new location, so it's unable to access the unsigned code / library / script, etc when it launches.The synthesized instance is not a copy of the app. Overall behavior is similar to nullfs on BSD, or using bind mounts on Linux.Question:Are there any new features in System Integrity Protection on Sierra, or will the functionality be the same as in El Capitan? If there are new features, what are they?Answer:Same functionality as in El Capitan.Question:Are there new restrictions in System Integrity Protection on Sierra, or do the restrictions currently m

Switching subscription groups
I have an app where fans can subscribe to multiple content creators and this is implemented using a sub group for each creator. I want to add a new all access subscription that gets them access to everything. We are treating this as an upgrade from the individual sub. Is there a way to cancel (or swap) the individual sub when they subscribe to the bundled sub? I know within a sub group it is possible to go between sub levels, but not sure about across sub groups.

How to Group UI aspects?
I'm new to programming on XCode and I'm currently messing with the UI trying to setup the program similar to a worksheet I have in real life. The worksheet has several boxes around the paper that are grouped so that statistics can be recorded and found easily. I would love to have my program look more like this, with grouped sets of statistics, but I've no idea how to do it. I would like to have a slighly shaded box that would have input fields in it. I hope that makes sense.My main concern is that currently Stack View really messes up my formatting but does in some way actually group toegther the 24 text fields I have. I'd also like it if this grouping allowed me to resize everything inside of it at the same time.I know its truly a noob situation but I've only been playing with this for 2 days.

Group Contacts
When will Group contacts be made available in apple mail app? Often users feel that their devices are a small extension of their office and to enhance productivity this would be a great addition, one that no other has done as of yet.

How to delete a subscription group?
I just changed my mind to have a one-time-purchase instead of subscriptions.However, I can see any way to delete the subscription group that I created before.It seems if you don't delete the group you will be REJECTED by the review team.😐Any ideas?

test groups in TestFlight
I'm not able to add more than one test group to a build that I've submitted for review for testing with TestFlight. Is that the intention of Apple or is it a bug? Will I be able to add other test groups after my build is approved by review?

MTLComputeCommandEncoder: what are SIMD groups?
MTLComputeCommandEncoder documentation mentions the concept of SIMD group, and there is even a void simdgroup_barrier(mem_flags flags) function in addition to the threadgroup_barrier one.Can someone please explain what a SIMD group is? Why that term and not a thread group?
