Swift 购买IAP订阅时，事务显示错误的状态

我正在将我们的iOS应用程序移植到MacOs上，遇到了一个奇怪的问题。当我购买自动续费订阅时，给定事务的事务状态不是

.purchased

，而是

.restored

。这毫无意义

@objc func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
        for transaction in transactions {
            switch transaction.transactionState {
            case .purchasing:
                handlePurchasingState(for: transaction, in: queue)
            case .purchased:
                handlePurchasedState(for: transaction, in: queue)
            case .restored:
                handleRestoredState(for: transaction, in: queue)
            case .failed:
                handleFailedState(for: transaction, in: queue)
            case .deferred:
                handleDeferredState(for: transaction, in: queue)
            @unknown default:
                SwiftyBeaver.debug("Payment: unknown error")
            }
        }
    }

这将错误地导致以下功能：

func handleRestoredState(for transaction: SKPaymentTransaction, in queue: SKPaymentQueue) {
        SKPaymentQueue.default().finishTransaction(transaction)
    }

但由于没有要恢复的内容，因此也不会调用最终函数：

@objc func paymentQueueRestoreCompletedTransactionsFinished(_ queue: SKPaymentQueue) {
        // once all items are restored, this gets called here:
        verifyWithTegantAPI()
    }

因此我们的Api没有被调用。用户现在必须再次点击Restore Purchases以激活购买，这一点并不理想

如果事务具有正确的状态，则会导致以下情况：

func handlePurchasedState(for transaction: SKPaymentTransaction, in queue: SKPaymentQueue) {

        SKPaymentQueue.default().finishTransaction(transaction)
        verifyWithServerAPI()
    }

购买本身是这样发生的：

func purchase(subscription: Subscription) {
        SwiftyBeaver.debug(subscription.product.productIdentifier)
        let payment = SKPayment(product: subscription.product)
        SKPaymentQueue.default().add(payment)
    }

请问我错过了什么
