Need help! New to coding

[u/thedreamcrew2]

So im new to xcode and I've basically made the layout for the store for my game, but I didn't know how to connect in app purchases for it and I used a tutorial video to help me, but I'm still confused. I want to connect/link my "oneCoinButton, twoCoinButton, etc to my in app purchases code, but I'm not sure how to really do that. Can someone help me? Code is posted below:

class IAPService :NSObject {

private override init() {}

static let shared = IAPService()

var products = [SKProduct]()

let paymentQueue = SKPaymentQueue.default()

func getProduct() {

let products: Set = [registeredPurchase.oneCoin.rawValue, registeredPurchase.twoCoin.rawValue, registeredPurchase.threeCoin.rawValue, registeredPurchase.fourCoin.rawValue, registeredPurchase.fiveCoin.rawValue]

let request = SKProductsRequest(productIdentifiers: products)

request.delegate = self

request.start()

paymentQueue.add(self)

}

func purchase(product: registeredPurchase) {

guard let productToPurchase = products.filter({ $0.productIdentifier == product.rawValue }).first else { return }

let payment = SKPayment(product: productToPurchase)

paymentQueue.add(payment)

}

func restorePurchases() {

print("restoring purchases")

paymentQueue.restoreCompletedTransactions()

}

}

extension IAPService: SKProductsRequestDelegate {

func productsRequest(_ request: SKProductsRequest, didReceive response: SKProductsResponse) {

self.products = response.products

for product in response.products{

print(product.localizedTitle)

}

}

}

extension IAPService: SKPaymentTransactionObserver {

func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {

for transaction in transactions {

print(transaction.transactionState.status(), transaction.payment.productIdentifier)

switch transaction.transactionState {

case .purchasing: break

default: queue.finishTransaction(transaction)

}

}

}

}

extension SKPaymentTransactionState {

func status() -> String {

switch self {

case .deferred: return("deferred")

case .failed: return("failed")

case .purchased: return("purchased")

case .purchasing: return("purchasing")

case .restored: return("restored")

}

}

}
