A Summary of the WWDC25 Group Lab

My girlfriend who is still on iOS 8 has been unable to send group messages without cellular data as well, so I don't think this is limited to iOS 9.

There are bridges between both versions to make life as easy as possible for hosts. v3 hosts can use v2 AUs while v2 hosts are required to make some minor API changes to be able to host v3 audio units.This information is discussed at about the 20min point in the WWDC Session < https://developer.apple.com/videos/wwdc/2015/?id=508 >.The summary comes down to the v2 host checking for a new flag kAudioComponentFlag_RequiresAsyncInstantiation and then using the new AudioComponentInstantiate insted of AudioComponentInstanceNew. There is also a new property from retrieving the v3 units view dependent on the flag kAudioComponentFlag_IsV3AudioUnit.The above Audio Unit Extensions presentation also has an accompanying v3 extension and host example for download.

If you can reproduce the problem on iOS 9 beta, these crashes would make for a fine bug report. Please post your bug number, just for the record.As for the total started download, yes it's about 2000-5000 thousands downloadsAgain, I'm having trouble parsing your sentences. Read literally, 2000-5000 thousands means 2-5 million, which is clearly not OK. I presume you mean 2-5 thousand. That should be OK, but it's obviously not in your case. Are you sure you're not 'leaking' tasks in the background session. That's easy to do and would definitely reduce the number of tasks that you could successfully execute.But in our real app, we may have around 50 000+ files to downloads sometimes, but we wanted to throttle them over time (~100 concurrent downloads). Will it be an issue?50,000 tasks is definitely beyond the pale. Batching them into groups of 100 should be fine.I expect you'd be able to increase that group size and I recommend that you do because of the resume rate limiter.Of course the best s

Yes, I would like to know how/if you actually solved this issue. I have been told several time in these forums by Apple staff that you can't share the keychain in WahtchOS 2.0 and the keychain access groups wont work either. I have not found a clear answer as to what the solution might be. Any inshight would be much appreciated. Thanks!

How Outlook for Mac uses the Autodiscover service to configure user accountsA user opens the Accounts dialog box in Outlook for Mac and provides an e-mail address and network credentials, such as user name and password, to configure a new Exchange Server account. Outlook for Mac then uses the Autodiscover service to configure the user’s profile.The Autodiscover service on the client tries to contact the Autodiscover service on the Exchange Server to obtain the user's connection settings by using one of the following methods: querying a set of predefined URLs based on the domain information in the user’s e-mail address, performing an HTTP redirect check, or by using a DNS Service Location (SRV) lookup.Autodiscover service tries to obtain the user's connection settingsNote: When Outlook for Mac connects to the HTTP redirection site or when it uses the DNS SRV method, users will see a dismissible warning message that asks them to verify that they are being redirected to a trusted URL. In this case, you must advi

Thank you for your reply.We were able to gain a better understanding about the differences between the [Group] and [Standard] containers.We'd like to ask you one more question about the [Group Container]. How do you differentiate the [Group Container] from [Keychain Sharing] for usage?We believe the following points apply to both: - The same data is accessible from multiple apps that meet specific conditions - Attack surface isn't just one app but multiple apps that meet specific conditionsCould you tell us how to differentiate the [Group Container] from [Keychain Sharing] for usage?

I have an input view and i have set empty bar button groups in the input assistant item. Until iOS 9 beta 2 it works fine. Ther was no extra bar above my input view. Since iOS 9 beta 3 an empty bar is shown above my input view.
