A Summary of the WWDC25 Group Lab

This issue keeps cropping up on the forums and so I decided to write up a single post with all the details. If you have questions or comments: If you were referred here from an existing thread, reply on that thread. If not, feel free to start a new thread. Use whatever topic and subtopic is appropriate for your question, but also add the Entitlements tag so that I see it. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = eskimo + 1 + @ + apple.com Determining if an entitlement is real In recent months there’s been a spate of forums threads involving ‘hallucinated’ entitlements. This typically pans out as follows: The developer, or an agent working on behalf of the developer, changes their .entitlements file to claim an entitlement that’s not real. That is, the entitlement key is a value that is not, and never has been, supported in any way. Xcode’s code signing machinery tries to find or create a provisioning profile to authorise this claim. That’s impossible, because t

Hello, I’m having trouble enabling Background Location updates on my iOS app. Xcode: 26.0 beta Team: Individual Developer Program (paid, activated recently) Device: iPhone (physical device, registered and provisioned) Problem When building to device, I get the error: Provisioning profile iOS Team Provisioning Profile: com.mybundle.id doesn't include the com.apple.developer.background-modes entitlement. Automatic signing failed. On the simulator the build succeeds, but on device the signing fails unless I remove the background-modes entitlement from .entitlements. What I tried Enabled Background Modes → Location updates in Signing & Capabilities (UI only). Info.plist contains UIBackgroundModes = location and the required NSLocation…UsageDescription keys. Cleaned Derived Data, removed cached provisioning profiles (~/Library/Developer/Xcode/UserData/Provisioning Profiles). Changed Bundle Identifier to force regeneration of provisioning profiles. Deleted and recreated provisioning profiles from Xcode. Tried b

Hi everyone, I'm using an app group to share data between iOS and it's watch companion app. I ensured that is has the same identifier in Signing & Capabilities and in the .entitlements files. Here is the UserDefaults part: class UserDefaultsManager { private let suitName = group.com.sanjeevbalakrishnan.Test public func saveItems(_ items: [ItemDTO]) { print(Save (items.count) items to shared defaults) let defaults = UserDefaults(suiteName: suitName) let data = try? JSONEncoder().encode(items) defaults?.set(data, forKey: items) } public func loadItems() -> [ItemDTO] { let defaults = UserDefaults(suiteName: suitName) print(defaults) guard let data = defaults?.data(forKey: items) else { print(watchOS received data is empty) return [] } let items = [ItemDTO].from(data: data) print(Load (items.count) items from user defaults) return items } } For testing I called loadItems after saveItems on iOS app and it returned items. However, on watchOS app it always returns empty array. What do I need to consi

We are facing an issue with Keychain sharing across our apps after our Team ID was updated. Below are the steps we have already tried and the current observations: Steps we have performed so far: After our Team ID changed, we opened and re-saved all the provisioning profiles. We created a Keychain Access Group: xxxx.net.soti.mobicontrol (net.soti.mobicontrol is one bundle id of one of the app) and added it to the entitlements of all related apps. We are saving and reading certificates using this access group only. Below is a sample code snippet we are using for the query: [genericPasswordQuery setObject:(id)kSecClassGenericPassword forKey:(id)kSecClass]; [genericPasswordQuery setObject:identifier forKey:(id)kSecAttrGeneric]; [genericPasswordQuery setObject:accessGroup forKey:(id)kSecAttrAccessGroup]; [genericPasswordQuery setObject:(id)kSecMatchLimitOne forKey:(id)kSecMatchLimit]; [genericPasswordQuery setObject:(id)kCFBooleanTrue forKey:(id)kSecReturnAttributes]; Issues we are facing: Keych

My entity has a startDate (NSTime) attribute where I use the date and time in my detail display of the entity. And in my list, I need to group my entities by day (YYMMDD) based on the start date; and I want to ensure that it can adapt to the region where the user is currently (e.g. if user travels or migrate, the YYMMDD should be adapted based on the current region). Does Core Data SectionedFetchRequest supports strftime() functions from SQLite (https://sqlite.org/lang_datefunc.html) or what is an effective alternative sectioned fetch in my case?

I am trying to add webhook subscriptions for TestFlight build processing completion and TestFlight beta build review completion events. These were showcased in the WWDC25 session: https://developer.apple.com/videos/play/wwdc2025/324/ Currently, I am able to receive webhook events for distribution updates, and the corresponding checkmark option is available in the App Store Connect portal. However, there is no checkmark option in the portal to subscribe to beta build-related events. In the video, there is clearly a checkmark option for the beta review event subscription (at 4:55). The current documentation also does not mention beta processing and beta review event subscriptions. It only lists the event types that are visible in the web portal: https://developer.apple.com/documentation/appstoreconnectapi/webhookeventtype When I try to add the BUILD_BETA_DETAIL_EXTERNAL_BETA_STATE_UPDATED event (as shown in the video at 6:10) via the PATCH API request, I get the below error. errors: [ { id: ****-****-*

What is the recommended way to obtain the concentric corner radius for views within grouped UICollectionView cells? In the most basic example, a UICollectionView with one section and one cell, we observe the cell takes almost the shape of a capsule, but it is indeed not a capsule. What is the way to obtain the radius of the grouped area from within the cell or its registration? I would like to layer elements on top that are concentric to the cell's clip shape. I've tried using custom views with .concentric UICornerConfigurations, setting .cornerConfiguration on the cell and on a custom backgroundView and I've even tried obtaining the .effectiveRadius of the cell after layout (returns 0.0). As of Xcode 26.0 Beta 7, nothing works. This seems like a huge omission; what am I missing here?

Summary In a SwiftUI drag-and-drop flow, the only robust way I’ve found to detect cancellation (user drops outside any destination) is to rely on the NSItemProvider created in .onDrag and run cleanup when it’s deallocated, via a custom onEnded callback tied to its lifecycle. On iOS 26, the provider appears to be deallocated immediately after .onDrag returns (unless I keep a strong reference), so a deinit/onEnded-based cancel hook fires right away and no longer reflects the true end of the drag session. I’d like to know: 1. Is there a supported, reliable way to detect when a drag ends outside any drop target so I can cancel and restore the source row? 2. Is the iOS 26 NSItemProvider deallocation timing a bug/regression or intended behavior? Minimal SwiftUI Repro This example shows: • creating a custom NSItemProvider subclass with an onEnded closure • retaining it to avoid immediate dealloc (behavior change on iOS 26) • using performDrop to mark the drag as finished import SwiftUI import UniformTypeIde
