I've recently published an app, and while developing it, I could always get consistent entitlements from Transaction.currentEntitlements. But now I see some inconsistent behaviour for a subscribed device in the AppStore version. It looks like sometimes the entitlements do not emit value for the subscriptions.
It usually happens on the first couple tries when the device goes offline, or on the first couple tries when the device goes online. But it also happens randomly at other times as well.
Can there be a problem with Transaction.currentEntitlements when the connectivity was just changed?
Of course my implementation may also be broken. I will give you the details of my implementation below.
I have a SubscriptionManager that is observable (irrelevant parts of the entity is omitted):
final class SubscriptionManager: NSObject, ObservableObject {
private let productIds = ["yearly", "monthly"]
private(set) var purchasedProductIDs = Set<String>()
var hasUnlockedPro: Bool {
return !self.purchasedProductIDs.isEmpty
}
@MainActor
func updatePurchasedProducts() async {
var purchasedProductIDs = Set<String>()
for await result in Transaction.currentEntitlements {
guard case .verified(let transaction) = result else {
continue
}
if transaction.revocationDate == nil {
purchasedProductIDs.insert(transaction.productID)
} else {
purchasedProductIDs.remove(transaction.productID)
}
}
// only update if changed to avoid unnecessary published triggers
if purchasedProductIDs != self.purchasedProductIDs {
self.purchasedProductIDs = purchasedProductIDs
}
}
}
And I call the updatePurchasedProducts() when the app first launches in AppDelegate, before returning true on didFinishLaunchingWithOptions as:
Task(priority: .high) {
await DependencyContainer.shared.subscriptionManager.updatePurchasedProducts()
}
You may be wondering maybe the request is not finished yet and I fail to refresh my UI, but it is not the case. Because later on, every time I do something related to a subscribed content, I check the hasUnlockedPro computed property of the subscription manager, which still returns false, meaning the purchasedProductIDs is empty.
You may also be curious about the dependency container approach, but I ensured by testing multiple times that there is only one instance of the SubscriptionManager at all times in the app.
Which makes me think maybe there is something wrong with Transaction.currentEntitlements
I would appreciate any help regarding this problem, or would like to know if anyone else experienced similar problems.
