Is there any way to read/write preferences for a Mac app group using the defaults command? I'm talking about the stuff you would programmatically manipulate using [NSUserDefaults initWithSuiteName:], and that is stored on disk in ~/Library/Group Containers. If I just say defaults read <suite name>, it tells me the the domain does not exist.

In a compute (kernel) function, is there an implicit ordering to threadgroup execution.Say I have a 32xN buffer. Take following trivial kernel (ignoring boundary conditions):kernel void example(device uint *buffer [[ buffer(0) ]], const uint2 pos [[ thread_position_in_grid ]]) { uint index = pos.y * N + pos.x; buffer[i - 1] = buffer[i] buffer[i + 1] = 0; }If we dispatch that kernel in N 32x1 threadgroups, is there any way that the thread groups are executed left-to-right? i.e. the resulting buffer is all 0 (once again, ignoring the boundary conditions).Thanks

I'm Trying add SwiftUI to Old Project. But Error in Group. How do I solve this problem? My Project: Xcode: 12.5.1 iOS Deployment Target: 13.0 Swift Compiler Error Static method 'buildBlock' requires that 'Group' conform to 'View' Trailing closure passed to parameter of type 'NSManagedObjectContext' that does not accept a closure

I would like to request the ability to group windows in mission control so that I can easily swap all windows between my 2 external monitors easily. Anyway to make swapping all windows between the displays easier would be a huge time saver. Making this an option in shortcuts would work as well.

How do I fix this?I have had this issue since we went from Me.com to iCloud.com with having 100's of duplicates of the same GROUP in my contacts via my iCloud.com account; which is my main iCloud account. I had created a secondary @me.com account that I use only for my Contacts and junk email (this was created at the same time as the iCloud.com transition).1.I have ran an Apple Script trying to delete these duplicates.2. I have spent hours on iCloud.com deleting this group. When I do this the screen will get darker and darker while I am hitting Delete then Enter to confirm the deletion. After a period of time the screen will return to normal and I will continue and the screen goes black again..3. I have tried deleting any files that I know of that are associated to my Contacts on my MacBook; is there another file or library that I can delete that might Reset this icloud account?

Hello. I need your help. We are developing an application where users provide premium content. Followers have to subscribe to each user's account to access their content through a renewable subscription. Like on Twitch application. Example: User 4 can subscribe to user 1, user 2 and user 3. He will pay every month, 3 subscriptions. The problem is that we can't create all the subscription groups manually because it would be too much work and not scalable. According to the documentation, if we have 1000 premium users (who sell their content), we have to create 1000 subscription groups manually and submit the application for each new selling user. How does Twitch make it possible for a user to subscribe to several accounts at the same time? Can I find documentation on this subject? Thanks in advance.

I am developing a macOS app, with an embedded Finder Extension - https://developer.apple.com/documentation/findersync/fifindersync and I want the app and the extension to share UserDefaults - https://developer.apple.com/documentation/foundation/userdefaults The App is Sandboxed for future distribution on the app store. I followed instructions here : https://developer.apple.com/library/archive/documentation/General/Conceptual/ExtensibilityPG/ExtensionScenarios.html#//apple_ref/doc/uid/TP40014214-CH21-SW1 Both targets are part of the same app group, as it can be seen in the Entitlements: com.apple.security.app-sandbox com.apple.security.application-groups $(TeamIdentifierPrefix)com.stormacq.mac.MyApp ttcom.apple.security.files.user-selected.read-only tt t 2. I am accessing the UserDefaults by the suiteName : t let defaults = UserDefaults.init(suiteName: TEAM_ID.com.stormacq.mac.MyApp) t //where TEAM_ID is the actual team id used to sign the app (something like 123AB45CDE) t However, when tr
