A Summary of the WWDC25 Group Lab

We read through all of the documentation, Xcode 7 header files, and tried to summarize everything we could figure out about watchOS 2. We hope this is a quick jumping off point for developers who just want a quick description and links directly into the Apple documentation. http://www.sneakycrab.com/blog/2015/6/8/watchos-20-tldrPlease give feedback, corrections and new discoveries, and we'll update the post with new information as we find it.

I have an app with CallKit Extension and when I try to pass data from ViewController to the Directory Extension with App Groups and UserDefaults I have this error:2017-11-12 13:42:07.199664+0100 CallKitTest[6851:2093165] [User Defaults] Couldn't read values in CFPrefsPlistSource<0x101a25f60> (Domain: group.com.rubenfernandez.CallKitTest, User: kCFPreferencesAnyUser, ByHost: Yes, Container: (null), Contents Need Refresh: Yes): Using kCFPreferencesAnyUser with a container is only allowed for System Containers, detaching from cfprefsdAny ideas?Thanks!

Does anyone know a workaround for the well-documented bug that makes XCode crash whenever you move a group? This bug is reproducible 100% of the time and has been documented as far back as early 2017, yet I'm sure there must be a way to move a group. The only suggestion I've read is to turn off source control, but I'm unwilling to do so and lose my editing history. I've tried moving files into the group before moving it, moving it in different way, nothing works. And what's worse of course is that you have to reopen XCode twice after the crash to return it to a usable state.

I have a series of apps that use the same user database. With my Facebook and email/password logins this is easy to identify the same user. However, the sign in with Apple creates a different user_id for the same user across my group of apps. How do I allow the same user to login with the same user_id across the app group?

Unable to select internal groups to the build that I've uploaded to the appstore. Why the group name is disabled?

Hi iPhone Developper,This is Hayto from Tokyo, Japan. I am looking for how to make product without levels into subscription groups.As I am quoting as follows, I found the document which refers that we can make single product. But I can not find how we can set single product without levels into subscription groups or products with same levels.All subscriptions must be part of a group, however you are not required to differentiate them into levels. For example, you can choose to offer a single subscription in-app purchase, or you can choose to offer multiple subscriptions and assign them all to the same level within the group.URL which I quoted is as follows.https://developer.apple.com/library/content/documentation/LanguagesUtilities/Conceptual/iTunesConnectInAppPurchase_Guide/Chapters/CreatingInAppPurchaseProducts.html#//apple_ref/doc/uid/TP40013727-CH3-SW10Could you kindly tell me how to make subscription product into subscription groups and how to make multiple products with same l

Hi all, I am on the Mac OS Monterey beta and I want an extension to handle some tab groups for me (switch to a specific tab group with a shortcut). Can someone guide me where I can find the documentation for tab groups in the safari extensions api.
