“A Summary of the WWDC26 Group Lab”

Currently, I am trying to learn how to program within Xcode. I have been reading the App Development with Swift book, and as such have been trying to use the labs within the book, to help with my understanding of the Swift programming language. However, whenever I try to open one of these labs, my computer screen starts to flicker, with sections of it going black for a second or two. Following this, all of the screen, except the mouse, will freeze completely. The clock freezes, every app freezes, and it will even stop midway through changing desktops. Sometimes, it will freeze indefinitely, and sometimes it will resume after half an hour if not more. I have had to force restart my computer several times as a result of the freezing.However, it only happens whenever I open the labs. Nothing else will cause this, and if I quit Xcode before it freezes, everything will go back to normal, so I’m relatively confident it’s not a hardware issue.I have deleted the labs, and then rein

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.

I took notes during the Custom app distribution and device management lab. If interested, please see the attached Notes from lab: Notes from lab

I asked a number of questions during the Q&A sessions Apple ran on the WWDC23 Slack instance and in Enterprise lab sessions. If interested, please see the attached Answered questions: Answered questions

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?

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?

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

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?

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.

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.

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

Is there any way to get the following pieces of information from a downloaded report ( can obviously get this from looking at appstoreconnect but I want to get it in an automated way.) Total subscriber count for a specific date Exact payment made to the bank account for a certain month Thanks

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?
