Reply to Disable iOS 26 UINavigationBar Auto Intvert Background and Title
You could try adjusting the edge effect using UIScrollEdgeEffect and specifying a different style. That said, starting in iOS 26, the recommendation is to reduce your use of custom backgrounds in navigation elements and controls. Any custom backgrounds and appearances you use in the navigation bar might overlay or interfere with Liquid Glass or other effects that the system provides, such as the scroll edge effect. To learn how to update your app to adopt Liquid Glass, see the following resources: Adopting Liquid Glass WWDC25 session 356: Get to know the new design system WWDC25 session 284: Build a UIKit app with the new design.

Reply to PHP and Swift interoperability
There was some discussion of language interoperability at WWDC25 this year. Please see the WWDC25 session Explore Swift and Java interoperability and the Related sessions listed on that page. Also, for server related stuff you may be interested in this Swift on Server article. For anything else you're thinking of that's not covered in those items, perhaps consider filing an enhancement request or participating in the Swift open source project. You can file an enhancement request using the Feedback Assistant. If you file the request, please post the Feedback number here so we can make sure it gets routed to the right team. If you're not familiar with how to file enhancement requests, take a look at Bug Reporting: How and Why?

Favorite Athlete Lab - Cell reuse identifier not found in scope
I'm working on the Favorite Athlete Lab - trying to complete it while accepting I don't understand everything it is teaching yet. I've encountered many challenges with the Lab but the current on is: I've set the cell reuse identifier of my cell to 'drinkCell' in the attributes inspector - but when I use it in the scenes ViewController, I get the error can not find 'drinkCell' in scope. I can see from the teacher resources how this has been solved there, but as far as I can tell, this solution has not be taught at any point so far, and isn't even mention in the subsequent section on cell dequeuing. let cell = tableView.dequeueReusableCell(withIdentifier: drinkCell, for: indexPath) Any help understanding this much appreciated.

Reply to Does AU Lab support AU v3?
AU Lab does not currently open audio unit extensions. I suggest filing a bug if having audio unit extension support in AU Lab is important to you. What makes the conversation interesting is then deciding how to provide a comparable iOS solution.

Thursday Education and Enterprise Deployment and Development Lab Notes
Question:Apple's Software Update service is marked as deprecated for macOS Sierra. For environments that want to test Apple updates before distributing them to their Macs, what is Apple's recommended approach for managing Apple software updates?Answer:For upgrade installs, you'll still have the Apple Software Update service available in Server.app.For new installs, the Software Update service will not be listed in Server.app's GUI. However, the functionality is still present in the current DP release and is manageable by the serveradmin command line tool.For new installs, the recommended approach is to use Caching Server. If you want to have management options added to Caching Server, file bugs and feature requests.The current shipping Software Update service for Server.app 5.1.x or older will continue to work. Apple is going to continue to maintain the software update catalogs, so other third-party solutions that use the SUS catalogs should continue to work.Question:Since in-app purchases still cannot be man

Questions for Security lab (Thursday, June 6th at 2:00 PM)
Question: Is there a way to mitigate HyperThreading vulnerability via MDM versus only NVRAM arguments passed in Recovery?Answer: No, because if it's available via MDM, it's also available to a potential remote attacker.Question: When a macOS MDM device upgrades to Catalina, what requirements does the device need to have in order to be considered Supervised? Is User Approved MDM enough to be considered supervised?Answer: Ask at the Device Management lab on Friday.Question: Does User-approved MDM provide the ability to run MDM commands available only to supervised Macs?Answer: Ask at the Device Management lab on Friday.Question: One of the bootstrap token criteria states: The Mac must be enrolled in an MDM solution associated with Apple School Manager or Apple Business Manager.Does this mean that this is for ONLY ABM-based MDM enrollments or does a UAMDM enrolled system whose MDM is also configured in DEP meet this requirement?Answer: Ask at the Device Management lab on Friday.Questio

App Store Connect does not show subscription summary correctly
Recently App Store Connect, Trends panel, Summary section does not show some of our subscription packages correctly even though we have many sales on those subscriptions.

@lijiaxu Adding to what Greg said, I recommend reviewing the section Prepare assets for gameplay for our WWDC25 sample Petite Asteroids. This article describes the process of loading complex geometry and using it to generate a collision mesh. Thank you for your question!

Reply to Polite location to store application data shared between users
I think /Library is a better option here. You wrote: if it means the application doesn't have to elevate privileges to write into the [/Library/Application Support] folder Privilege escalation is a feature, not a bug, IMO. Most Macs have a single user. For those Macs that have multiple users, many of them are deploying in managed environments: a Mac where the parents ‘manage’ the kids, a school lab full of Macs, and so on. If you use /Users/Shared, you run the risk of a managed user messing up your app’s state for other managed users. Having said that, privilege escalation is a pain. For a summary of the issues, see BSD Privilege Escalation on macOS. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = eskimo + 1 + @ + apple.com

Does group messaging work properly?
I've got the beta installed on my iPad Mini 2. I just happened to look at the message responses to a group message that I sent which originated from my iPhone 6 Plus (on iOS 8.3) which was sent to a mix of iMessage and regular SMS accounts, and while my original group message was contained in a group message thread, all the responses to it came back in individual threads. I verified that on my iPhone they are all coming back as part of the group message thread. Only seems to be an issue on the iPad and on the iPad with iOS 9 (previous group messaging on iOS 8.3 and below worked as expected).I also checked in Settings -> Messages to see if the Group Messaging option was enabled, and it isn't there anymore. (For that matter, neither is MMS Messaging.) Can anyone else verify that Group Messaging is or isn't working for them as expected?

Reply to Will Apple Intelligence Support Third-Party LLMs or Custom AI Agent Integrations?
Hello, Thank you for your interest in Apple Intelligence, ChatGPT and agentic AI. We're unable to speak about roadmap plans, and in general about any unannounced technologies (real, imagined or hallucinated). For the latest announcements please attend WWDC25.
