A Summary of the WWDC25 Group Lab

During the Camera lab session at WWDC25, support for DICOM was mentioned. I'm trying to work with the new AVFileType dcm to help with handling DICOM scans. Can anyone provide some assistance?

We are seeking clarification on the behavior of App Store Server Notifications V2. Summary In our production environment, we received a notification with notificationType: DID_FAIL_TO_RENEW and subtype: GRACE_PERIOD. However, the gracePeriodExpiresDate field in the payload was null. We understand this notification indicates that a user's subscription has entered a grace period. The null value for its expiration date is unexpected, and we are looking for an official explanation of this behavior and the correct way to handle it. The Scenario Here are the details of the notification we received: Notification Type: DID_FAIL_TO_RENEW Notification Subtype: GRACE_PERIOD Environment: Production Upon decoding the signedRenewalInfo JWS from the responseBodyV2, we found that the gracePeriodExpiresDate field inside the JWSRenewalInfoDecodedPayload was null. The notificationUUID for this event was in the format xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx. Our Implementation and its Impact Our backend is designed to ensu

We are experiencing a significant issue with macOS security alerts that began on July 9th, at approximately 4:40 AM UTC. This alert is incorrectly identifying output files from our snippet tests as malware, causing these files to be blocked and moved to the Trash. This is completely disrupting our automated testing workflows. Issue Description: Alert: We are seeing the Malware Blocked and Moved to Trash popup window. Affected Files: The security alert triggers when attempting to execute .par files generated as outputs from our snippet tests. These .par files are unique to each individual test run; they are not a single, static tool. System-Wide Impact: This issue is impacting multiple macOS hosts across our testing infrastructure. Timeline: The issue began abruptly on July 9th, at approximately 4:40 AM UTC. Before that time, our tests were functioning correctly. macOS Versions: The problem is occurring on hosts running both macOS 14.x and 15.x. Experimental Host: Even after upgrading an experimental host to m

Hello Apple team and community, I’m reporting a critical issue affecting iPhone 13 (128 GB) on iOS 26 Public Beta 3. Problem Summary: • Device stays stuck at 1% battery, even while charging • Battery Health shows 0% in Settings • Phone reboots every 5 minutes while unplugged • Only works when connected to power • Cannot update, charge properly, or maintain uptime Additional Context: • The issue appeared immediately after installing iOS 26 beta 3 • Affected devices often have a replaced battery (even official or high-quality replacements) • Seems to be a software validation bug related to battery firmware • Reported by many users across Reddit, Apple Forums, and Twitter — but not listed in Known Issues What Has Been Tried: • Recovery Mode / Safe charging / Clean install (same version) – no effect • Third-party repair tools (ReiBoot, 3uTools) — partial workaround • Jailbreak with Nugget or iCleaner to disable crash daemons – temporarily helps • Apple Support suggested full device replacement (!) ⸻ Requ

Hello Apple Developer Community, I am facing a persistent issue with my iOS TestFlight builds that keeps getting rejected for Guideline 2.1 - Performance - App Completeness, specifically Your app failed to load any content at launch. (blank white screen). My app is With Wans Camp Map (App ID: com.jiro.withwanscampmap). Here's a summary of the situation: App Functionality: The app uses Google Sheets API to fetch campsite data (pins) and Google Maps API to display them on a map. Local Development (Expo Go): When running the app locally using npx expo start and connecting with the Expo Go app, and with the Google Cloud Platform (GCP) API key Application restrictions set to None (no restriction), the app loads successfully and displays all pins correctly. This confirms the API keys themselves and the data fetching logic are working. TestFlight Builds (Rejected): All attempts to upload builds via EAS Build (profile preview with autoIncrement: true in eas.json) and Transporter have resulted in rejection wi

I have this very simple PersistenceController setup. It's used in both the main app and widget target. struct PersistenceController { static let shared = PersistenceController() @MainActor static let preview: PersistenceController = { let result = PersistenceController(inMemory: true) let viewContext = result.container.viewContext return result }() let container: NSPersistentContainer /// The main context. var context: NSManagedObjectContext { return container.viewContext } init(inMemory: Bool = false) { container = NSPersistentContainer(name: Gamery) if inMemory { container.persistentStoreDescriptions.first!.url = URL(fileURLWithPath: /dev/null) } else { do { let storeURL = try URL.storeURL(forAppGroup: XXXXXXXXXX, databaseName: Gamery) let storeDescription = NSPersistentStoreDescription(url: storeURL) /// Enable history tracking for cloud syncing purposes. storeDescription.setOption(true as NSNumber, forKey: NSPersistentHistoryTrackingKey) print(### Persistent container location: (storeURL)) container.persi

Hi, Our recent security scans, performed by Data Theorem, have flagged a potential App Store blocker related to the use of a private iOS class, NSBlock. We are concerned that this identified warning may lead to our apps being rejected during the next App Store submission. Issue Summary: We integrate a library, this SDK is developed using Kotlin Multiplatform, and during compilation, Kotlin automatically generates Objective-C/Swift interoperability code. As a result of this code generation, the compiled framework includes a reference to a private Apple class, NSBlock. It’s important to note that: No methods or functionality from NSBlock are being invoked or used. This reference is auto-generated by Kotlin’s ObjCExport.mm module. For additional context, you may refer to a related discussion on this issue: https://github.com/ricohapi/theta-client/issues/98 https://github.com/JetBrains/kotlin-native/issues/1642 https://github.com/JetBrains/kotlin-native/pull/1652/files We would like to confirm whether th

I am trying to recreate the kind of header view from the WWDC25 video Design foundations from idea to interface. I've tried using a ScrollView and using Geometry reader, but couldn't figure it out and as this was showcased in the WWDC session, is there an easier way to achieve this style? Thanks in advance!
