A Summary of the WWDC25 Group Lab

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

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?

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?

All identifiers updated in summer 2020 has new value for keychain-access-groups - com.apple.token. What is its purpose? What can happen if this value will not be added to entitlements?

I am adding Group Activities integration with a MacCatalyst app. I have added the Group Activities entitlement in Xcode. I also checked the entitlements with : codesign --display --entitlements :- I can see the entitlement : com.apple.developer.group-session The feature work fine on iPadOS but when I run it on MacOS, the GroupActivitySharingController is not loading properly. I get the following error messages: Cannot run query EXQuery: extension point com.apple.groupactivities platforms: 6 with error: (null) Failed to lookup extension with query EXQuery: extension point com.apple.groupactivities platforms: 6 on <_GroupActivities_UIKit.PeoplePickerController: 0x600005020980> Failed to fetch config for hostViewController <_GroupActivities_UIKit.PeoplePickerController: 0x600005020980> Failed to build remote hostViewController for <_GroupActivities_UIKit.GroupActivitySharingController: 0x1417f1250> Failed to fetch extensionViewController Calling -viewDidAppear: directly on a v

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

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

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?

Hi everyone, I just started to get income on the App Store and I'm trying to figure out how the financial reports section works. One thing I can't understand is why do I have 2 sets (groups) of transactions when I browse the report for June 2020. The 1st group says I have income of about 50 CAD (with a set of countries in it if I unfold the group) and 37 sales. The 2nd group right below the first one says I have 4 USD income and 3 sales. Why the currency is different if I chose my account currency as CAD and why the transactions have been split in those groups? Moreover, the 1st group has the following countries : Australia, Canada, China, Europe, Japan, Russia, North And South America. And all those transactions are converted to CAD as I expect. The second group has only Great Britain and Poland and their transactions are converted into USD, why's that?

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?
