Hi, I’m seeing a reproducible issue with local StoreKit testing on the iOS 26.4 Simulator. Environment: Xcode 17E192 iOS 26.4 Simulator StoreKit Testing in Xcode using a .storekit configuration file attached to the Run scheme SubscriptionStoreView StoreKit 2 What happens: Tapping a subscription purchase button starts the flow, but the purchase immediately returns: StoreKit.Product.PurchaseResult.userCancelled No purchase dialog appears. No transaction is created. Debug > StoreKit > Manage Transactions remains empty. Transaction.updates, Transaction.unfinished, and Transaction.currentEntitlements do not produce any new purchase-related events. Important detail: This happens not only in my app, but also in Apple’s sample: Implementing a store in your app using the StoreKit API I tested the sample with its own .storekit file and shared scheme. The sample shows the same behavior on iOS 26.4 Simulator. On iOS 26.2 Simulator: The purchase flow does react differently. I see the warning: Making a purchase without listening for transaction updates risks missing successful purchases. Create a Task to iterate Transaction.updates at launch. So 26.2 does not appear completely broken in the same way. What I already checked: The .storekit file is attached to the active Run scheme. Simulated failures are disabled: _disableDialogs = false _failTransactionsEnabled = false _storeKitErrors = [] I tried both SubscriptionStoreView(groupID:) and SubscriptionStoreView(productIDs:) I erased app data, reinstalled, and tested on a fresh simulator. Manage Transactions has no records at all. My own app and Apple’s sample both reproduce the issue on 26.4 Simulator. This makes me suspect a simulator/runtime regression in local StoreKit testing on iOS 26.4 rather than an app-specific bug. Has anyone else seen this on iOS 26.4 Simulator? Is this a known issue with StoreKit Testing in Xcode on the 26.4 runtime? If needed, I can provide the exact simulator/Xcode versions and a minimal repro using Apple’s sample project.
