A Summary of the WWDC25 Group Lab

Hello Engineers My app was rejected with the message below, BUT I don't have this entitlements in my project! I already removed all Xcode files under ${HOME}/Developer/Xcode, but the problem still alive! Guideline 2.4.5(i) - Performance In order to continue reviewing your app, we require additional information. Your app uses one or more entitlements which do not appear to have matching functionality within the app. Please reply to this message in App Store Connect and describe how and where the app uses the following entitlements. You will not need to upload a new binary to provide this information. Apps should have only the minimum set of entitlements necessary for the app to function properly. If there are entitlements that are not needed, please remove them and submit an updated binary. You will need to Developer Reject the app to upload an updated version. com.apple.security.assets.pictures.read-write com.apple.security.assets.movies.read-write com.apple.security.assets.music.read-write com.apple.security

Consider the following in an AppIntent: struct TestIntent: AppIntent { static let title: LocalizedStringResource = Test Intent static var parameterSummary: some ParameterSummary { Summary(Test) { .$options } } enum Option: Int, CaseIterable, AppEnum { case one case two case three case four case five case six static let typeDisplayRepresentation: TypeDisplayRepresentation = TypeDisplayRepresentation( name: Options ) static let caseDisplayRepresentations: [Option: DisplayRepresentation] = [ .one: DisplayRepresentation(title: One), .two: DisplayRepresentation(title: Two), .three: DisplayRepresentation(title: Three), .four: DisplayRepresentation(title: Four), .five: DisplayRepresentation(title: Five), .six: DisplayRepresentation(title: Six), ] } @Parameter(title: Options, default: []) var options: [Option] @MainActor func perform() async throws -> some IntentResult { print(options) return .result() } } In Shortcuts, this will turn into a dropdown where you can check multiple Option values. However, wh

I am new to swift development, and it's possible that I'm missing something fundamental/obvious. If so, I apologize in advance. My team is developing an application for iPadOS using SwiftUI, and I'm trying to accomplish something similar to what the original inquirer is asking for in this thread: https://developer.apple.com/forums/thread/725152. The only difference is that I'm trying to use a PIV smart card to achieve authentication to a server rather than digitally sign a document. Unfortunately, I'm getting stuck when attempting to run the list() function provided in the accepted answer to the post mentioned above. When attempting to call SecItemCopyMatching(), I'm getting a -34018 missing entitlement error. I've attempted to add the com.apple.token to my app's keychain-access-groups entitlements, but this does not resolve the issue. I have checked the entitlements in my built app, per the recommendation in the troubleshooting guide here: https://developer.apple.com/forums/thread/114456. The entitl

ISSUE SUMMARY: iOS app receives The app contains one or more corrupted binaries error during Apple's SPI (Static Program Interface) analysis after successful upload to App Store Connect. Exhaustive systematic debugging indicates this is an Apple validation infrastructure issue, not application code.

Hello, I’m building an app that helps people spend less time on social media apps. For that, I make heavy use of Apple’s Screen Time APIs, such as ManagedSettings and FamilyControls. When an app is locked using a ShieldConfiguration, the user has to open my app in order to unlock it (e.g. enter a code). This is very cumbersome because no documented API exists to open the parent app (=my app) from the ShieldActionDelegate (also part of my app) when the user presses a button of the ShieldConfiguration. The ShieldActionDelegate callback just offers three options in its ShieldActionResponse: .none .defer .close .openParentApp is missing. We are working around this limitation by sending a local push notification that the user has to tap on. This has multiple drawbacks: It has to be ensured that notification permission has been granted. It has to be ensured that notifications can be delivered even while focus is enabled. Features such as Apple Intelligence notification summaries and notification prioritiza

We are developing a native iOS financial application called Tradu: Stocks, Forex, and CFDs (Apple ID: 6473443264), which embeds a WKWebView to render all user-facing logic. All user interactions—including authentication with MFA—occur inside this WKWebView. To access native functionality, we use postMessage() to communicate between the web and native layers. This approach has worked successfully for biometric authentication, for example. We are currently integrating Apple Pay In-App Provisioning and have a few questions regarding compliance with the documentation provided by our Issuer Host (Modulr). In the document titled Getting Started with Apple Pay: In-App Provisioning, Verification, Security, and Wallet Extensions (Version 4.0, February 2023), all examples are based on a fully native application. We’ve managed to integrate most of the In-App Provisioning flow via postMessage() up to the point of passing encryptedData to the Payment View.

WWDC25: Combine Metal 4 machine learning and graphics Demonstrated a way to combine neural network in the graphics pipeline directly through the shaders, using an example of Texture Compression. However there is no mention of using which ML technique texture is compressed. Can anyone point me to some well known model/s for this particular use case shown in WWDC25.
