latestTransaction

Declaration

var latestTransaction: VerificationResult<Transaction>? { get async }

Discussion

This value is nil if the customer has never purchased this product. The following code example illustrates requesting the most recent transaction for a product to determine whether the customer has purchased the product:

guard let resultingTransaction = await product.latestTransaction else {
    // The customer hasn't purchased this product.
    return
}
guard case .verified(let transaction) = resultingTransaction else {
    // Ignore unverified transactions.
    return
}
// Update your app based on the details from the most recent transaction.

By default, when the SKIncludeConsumableInAppPurchaseHistory property list key is false, this value excludes finished consumable in-app purchases unless they are refunded or revoked.

If you set the SKIncludeConsumableInAppPurchaseHistory property list key to true, this value returns all transactions, including consumable in-app purchases that your app marked as finished (finish()).
