A Summary of the WWDC25 Group Lab

(Note: this is part 2 of a 3 part posting. See Part 1 or Part 3) At WWDC25 we launched a new type of Lab event for the developer community - Group Labs. A Group Lab is a panel Q&A designed for a large audience of developers. Group Labs are a unique opportunity for the community to submit questions directly to a panel of Apple engineers and designers. Here are the highlights from the WWDC25 Group Lab for Camera & Photos. WWDC25 Camera & Photos group lab ran for one hour at 6 PM PST on Tuesday June 10th, 2025 Question 10 Can we directly integrate auto-capture triggers (e.g., when image is steady or text is detected) using Vision and AVFoundation? Yes apps can use AVCaptureSession's VDO + AVCapturePhotoOutput, run vision on VDO buffers and capture photo when certain scene or text is detected. Just to be careful to run Vision on VDO buffers async so it doesn't cause frame drops

We are really excited to have introduced the Foundation Models framework in WWDC25. When using the framework, you might have feedback about how it can better fit your use cases. Starting in macOS/iOS 26 Beta 4, the best way to provide feedback is to use #Playground in Xcode. To do so: In Xcode, create a playground using #Playground. Fore more information, see Running code snippets using the playground macro. Reproduce the issue by setting up a session and generating a response with your prompt. In the canvas on the right, click the thumbs-up icon to the right of the response. Follow the instructions on the pop-up window and submit your feedback by clicking Share with Apple. Another way to provide your feedback is to file a feedback report with relevant details. Specific to the Foundation Models framework, it’s super important to add the following information in your report: Language model feedback This feedback contains the session transcript, including the instructions, the prompts, the responses, e

Hello, I am seeking guidance regarding the com.apple.managed.vpn.shared keychain access group entitlement for our iOS app, which is required to support managed VPN configurations distributed via MDM profiles. Background: Our app uses the Network Extension framework and requires access to VPN credentials stored in configuration profiles, which—according to Apple documentation and forum posts—necessitates the com.apple.managed.vpn.shared entitlement We have already enabled the standard Network Extension entitlements via the Apple Developer portal What I Have Tried: I referenced the advice from a past Apple DTS engineer in this forum post: https://developer.apple.com/forums/thread/67613 I have submitted multiple requests to Apple Developer Technical Support (DTS) over the past two months, clearly explaining our use case and referencing the official documentation as well as the above forum thread Unfortunately, I have either received no response or responses that do not address my request for the special

Dear Apple Developer Technical Support, I am encountering an issue with notarizing and stapling both PKG and DMG installers for our Electron-based macOS application COSGrid. Despite receiving successful notarization submission responses via notarytool, the stapling process fails with Error 65.

After iOS 18, some new categories of crash exceptions appeared online, such as those related to the sqlite pcache1 module, those related to the photo album PHAsset, those related to various objc_release crashes, etc. These crash scenarios and stacks are all different, but they all share a common feature, that is, they all crash due to accessing NULL or NULL addresses with a certain offset. According to the analysis, the direct cause is that a certain pointer, which previously pointed to valid memory content, has now become pointing to 0 incorrectly and mysteriously. We tried various methods to eliminate issues such as multi-threading problems. To determine the cause of the problem, we have a simulated malloc guard detection in production. The principle is very simple: Create some private NSString objects with random lengths, but ensure that they exceed the size of one memory physical page. Set the first page of memory for these objects to read-only (aligning the object address with the memory page). After a r

Group Labs are a unique opportunity for the community to submit questions directly to a panel of Apple engineers and designers. Here are the highlights from the WWDC25 Group Lab for Machine Learning and AI Frameworks. What are you most excited about in the Foundation Models framework? The Foundation Models framework provides access to an on-device Large Language Model (LLM), enabling entirely on-device processing for intelligent features. This allows you to build features such as personalized search suggestions and dynamic NPC generation in games. The combination of guided generation and streaming capabilities is particularly exciting for creating delightful animations and features with reliable output. The seamless integration with SwiftUI and the ne

Can you expand on how Liquid Glass helps with navigation and focus in the UI? Liquid Glass clarifies the navigation layer by introducing a single, floating pane that acts as the primary navigation area. Buttons within this pane seamlessly morph as you move between sections, and controls can temporarily lift into the glass surface. While avoiding excessive use of glass (like layering glass on glass), this approach simplifies navigation and strengthens the connection between menus, alerts, and the elements that trigger them. What should I do with customized bars that

What's your favorite new feature introduced to SwiftUI this year? The new rich text editor, a collaborative effort across multiple Apple teams. The safe area bar, simplifying the management of scroll view insets, safe areas, and overlays. NavigationLink indicator visibility control, a highly requested feature now available and back-deployed. Performance improvements to existing components (lists, scroll views, etc.) that come for free without requiring API adoption. Regarding performance profiling, it's recommended to use the new SwiftUI Instruments tool when you
