Как настроить непотребляемую покупку в приложении в UIKit с помощью StoreKit 2 ⇐ IOS

[Anonymous]

Я использую приведенный ниже код для непотребляемых покупок в своих приложениях. Кто-нибудь придумал, как справиться с этим с помощью StoreKit 2 и UIKit? Я просмотрел документацию Apple и загрузил пример кода, но не понимаю, как это сделать в UIKit.
SKPaymentQueue — устарел

SKPayment — устарело

SKProduct — устарело

transactionState — устарело

SKPaymentTransaction — устарело

finishTransaction – устарел
func paymentQueue(_ queue: SKPaymentQueue, shouldAddStorePayment payment: SKPayment, for product: SKProduct) -> Bool
{
true
}

func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction])
{
for transaction in transactions
{
switch transaction.transactionState
{
case .purchasing:
break

case .purchased:

SKPaymentQueue.default().finishTransaction(transaction)

// Hide the restore button
navigationItem.setRightBarButton(nil, animated: true)

// Set the ProVerion in the Db to true
IAPHandler.setProVersionToPurchased()

// Also hide the Purchase button
UIView.animate(withDuration: 1.0, animations: { [weak self] in
self?.purchaseBtn_Outlet.alpha = 0
}) { [weak self] (success) in

if self!.theDevice.isOneOf(K.Device_Groups.SE_3_iPhone8) {
self?.segControlTop_Constraint.constant = 10

} else if self!.theDevice.isPhone {
self?.segControlTop_Constraint.constant = 30
}
}

case .failed:
if let error = transaction.error
{
let errorDescription = error.localizedDescription
print("Transaction failed due to error: \(errorDescription)")
}

case .restored:

SKPaymentQueue.default().finishTransaction(transaction)

// Hide the restore button
navigationItem.setRightBarButton(nil, animated: true)

// Set the ProVerion in the Db to true
IAPHandler.setProVersionToPurchased()
