“A Summary of the WWDC25 Group Lab”

If I search for regex (.*)How do I replace with the capture group? It was 0 and then $0. Any clue what it is in the new editor?For bonus points: can I change the case on the capture groups?Thanks,Andrew

Is it possible to change the Primary App ID set in the Group with an existing primary App ID to another Primary App ID within the same group If there is a change, whether the sub values of the token will be changed upon successful login If an app corresponding to the existing Group Primary App ID is deleted from the app store, ask whether or not other apps in the same group are affected and what effect it will have If anyone knows about the above, please let me know please

Is there any documentation aside from the Metal Shading Language Specification that explains the SIMD group functions such as simd_or simd_and simd_xor etc. CUDA has functions comparable to the vote/ballot simd functions, but I am not aware of anything similar to the above. The MSL specification is vague in stating - for example - simd_or returns the bitwise OR across all active threads. Does that mean T data is applied bitwise to the value in each SIMD lane? What does that return exactly? Do you get only the highest or lowest or a sum of the bitwise operation?

I'd like to know if there is a way to limit the number of participants in a group activity (SharePlay). Looking through the API, I could not find anything regarding limiting or requiring the number of participants.

I'm wondering if anyone else is seeing this:it looks to me like the Responsible caller value in the allocation summary is misleading, and randomly dropping to stack frames. for example, right now i'm looking at a summary that has these three lines (among others):Retain -[Solution initWithContentsOfURL:] Retain -[Solution init] Release -[Solution init]seems line 2 and three match, right? think again. if you look at the full stack frames for each, you see this: 0 Fire -[Solution init] /Users/mh/Code/Fire/SharedProjectSystem/Solution.cs:0 1 Fire -[Solution initWithContentsOfURL:] /Users/mh/Code/Fire/SharedProjectSystem/Solution.cs:85 2 Fire +[Solution solutionWithContentsOfURL:] /Users/mh/Code/Fire/SharedProjectSystem/Solution.cs:664 3 Fire -[SolutionDocument readFromURL:] /Users/mh/Code/Fire/SharedCoreApp/SolutionDocument.cs:70 4 Fire -[SolutionDocument readFromURL:ofType:error:] /Users/mh/Code/Fire/SharedCoreApp/SolutionDocument.NSDocument.cs:78 5 AppKit -[NSDocument _initForURL:withContentsO

That's a watch error I cannot get rid of.I have created a group at the bottom of the view (that seem to be important).In the group, a label and a slider.I would like to hide the group at start, then show it after some action has been done.So, in awake, I setHidden(true) for the group.But, I get multiple context errors like:App Watch Extension[11882:866609] [Unknown process name] CGContextSetFillColorWithColor: invalid context 0x0. If you want to see the backtrace, please set CG_CONTEXT_SHOW_BACKTRACE environmental variable.App Watch Extension[11882:866609] [Unknown process name] CGContextSetStrokeColorWithColor: invalid context 0x0. If you want to see the backtrace, please set CG_CONTEXT_SHOW_BACKTRACE environmental variable.If I replace setHidden by setting alpha to 0, I succeed in hiding, but that's not exactly the same layout.I found this SO, but the solution does not work for me.https://stackoverflow.com/questions/32236204/cgcontextsavegstate-invalid-context-0x0-error-only-on-de

When printing a GroupSession object I see that locallyInitiated is included in the print and I would like to update / prepare my UI based on the initiator of the Group Session. Can locallyInitiated be added as a property to the GroupSession object?

In the 2020 WWDC changes to the Developer site, the section in Profiles for Keychain Access Groups went away. I understand that this entitlement is now rolled into App Groups, but I don't see my preexisting Access Group identifier listed on my page anymore. Where do I modify or remove the Access Group entitlement I've been using, or create new ones?

In a watch app, if I put a label inside a Group , setText() does not change the text on a label when it is inside a Group.The demo code:@IBOutlet var pinLocationText: WKInterfaceLabel! @IBAction func pinButtonPress() { pinLocationText.setText(Reset) }executes correctly when pinLocationText is outside a Group, but fails to display the text when the label is inside a Group.So, how do I update the display value of a Label when it is inside a Group?

I'm trying to share cached data between a tvOS app and a TVService extension. I crated an app group and get a directory based on the identifier. All works fine in the simulator. On the tvOS dev kit however the app does not have write permission the app group directory.I realize the restrictions on tvOS but shared cache data in app groups should be possible according the FAQ:For temporary local storage, apps may access the NSTemporaryDirectory and NSCachesDirectory in their own container, or NSCachesDirectory in a shared container.So how do I get access to the caches in the app group container? has anybody here got this working?

The shortcut app seems to have a bug regarding text match grouping when trying to match a lowercase string to a capital case one. The match happens, but the regular expression groups are not properly displayed. To replicate, create a shortcut with the following actions: Match d-(george) in 2-George check case-insensitive on Show Matches (this will show 2-George) Get Group At Index 1 in Matches Show Text This will not print anything

Anyone else have issue where group chats are being split, only working that way on my devices running iIpados 15.2
