In-App Purchase Product ID in Xcode

App Development
1

Hi, I’m trying to enter my Product ID’s in Xcode. The In-App Purchased code is already set up, I just need some information on where I can place the Product ID’s in Xcode that created in App Store Connect.

Any help will be much appreciated. :slight_smile:

Thank you,
Clarissa

Welcome to the community Clarissa!!

You can put them in a constants file. It’s a file of constant strings, so you can then refer to them anywhere in the code, and not have to type a string value everywhere.

Create a new Swift file, name it Constants.swift

In the file:

enum Constants {

   static let prodID1 = “name you put in AppStoreConnect”
   static let prodID2 = “name you put in AppStoreConnect”
}

here’s the Code I have for making my in-app purchase. you should be able to tailor it for your needs. the code I have in the ‘fail’ case is actually the success logic. When I run it on my phone to test it, it will only go through the fail path so I put it there to test that the logic works.

import UIKit
import StoreKit

 class UpgradeController: UIViewController, SKProductsRequestDelegate,     SKPaymentTransactionObserver {

let model = DataModel()

var myProduct: SKProduct?
var user: User?



@IBOutlet weak var imageLock: UIImageView!


@IBOutlet weak var buttonPurchase: UIButton!

override func viewDidLoad() {
    super.viewDidLoad()

    print (user!.nameLast!)
    print (user!.unlimited)
    fetchProducts()
    
}



//MARK: FETCH PRODUCT
func fetchProducts() {
    /
    print ("fetch products")
    
    let request = SKProductsRequest(productIdentifiers: ["YOURPRODUCTNAMEHERE"])
    
    request.delegate = self
    request.start()
    
}






@IBAction func buttonActionPurchase(_ sender: Any) {
    
    guard let myProduct = myProduct else {
        return
    }

    if SKPaymentQueue.canMakePayments() {
        let payment = SKPayment(product: myProduct)
        SKPaymentQueue.default().add(self)
        SKPaymentQueue.default().add(payment)
    }

}



//DELEGATE METHODS
func productsRequest(_ request: SKProductsRequest, didReceive response: SKProductsResponse) {
    
    print ("made it to delegate function")
    
    if let product = response.products.first {
        
        myProduct = product
        print (myProduct?.productIdentifier)
        print (myProduct?.localizedDescription)
        print (myProduct?.localizedTitle)
        print (myProduct?.price)
        print (myProduct?.priceLocale)
        
    }
    
}







func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
    
    for transaction in transactions {
        
        switch transaction.transactionState {
        
        case .purchasing:
            print ("purchase is in process")
            
            break
        
        case .purchased, .restored:
            print ("purchase was made")
            
            UserDefaults.standard.set(true, forKey: "Unlimited")
            

            
            SKPaymentQueue.default().finishTransaction(transaction)
            SKPaymentQueue.default().remove(self)

            user?.unlimited = true
            print (user!.unlimited)
            
            model.updateToUnlimited(self.user!)
            
            //TODO: UNLOCK LOCK
            imageLock.image = nil
            
            break
        
        case .failed, .deferred:
            print ("purchase failed")
            
            self.user?.unlimited = true
            print (self.user!.unlimited)
            
            model.updateToUnlimited(self.user!)
            
            //TODO: UNLOCK LOCK
            imageLock.image = nil
            
            SKPaymentQueue.default().finishTransaction(transaction)
            SKPaymentQueue.default().remove(self)
           

            
            
            
            break
            
        default:
            print ("default")
            
            SKPaymentQueue.default().finishTransaction(transaction)
            SKPaymentQueue.default().remove(self)
        }
    }
    
}

Thank you for your help!
I have one question. How do I add a Privacy Policy and Terms of Use links to the Subscription Screen?

The subscription screen is set up, I just need to add those links to submit.

Very Much Appreciated,
