XCode version = 26 && macOS version = 26
Running the app from XCode (not in release mode)
I want to implement in app purchases for my macOS application, for that i want to first test it locally through StoreKit config file.
Steps i have done uptill now:
- Added the capability in target-> Signing & Capabilities -> In_App Purchase(while adding this i had got the popup: Make changes to In-App Purchase by changing all configurations - i have no idea about it, Researched on it - didnt got something)
- Added the storekit config file -> added Group for autorenewable subscription -> reference name & product ID (i have used same Bundle ID and product ID, also i have used different both but still the same issue in both case) - also added it to scheme
- Added the storeManager implementation that is:
import StoreKit
class IAPManager {
// Shared instance (optional singleton pattern)
static let shared = IAPManager()
private init() { }
// Array to store fetched products
var products: [Product] = []
// MARK: - Fetch Products
func fetchProducts() async {
let productIDs = ["com.app.yearly"]
do {
// Fetch products from StoreKit
let fetchedProducts = try await Product.products(for: productIDs)
self.products = fetchedProducts
print("✅ Successfully fetched products:")
for product in fetchedProducts {
print("----------------------------")
print("Product ID: \(product.id)")
print("Display Name: \(product.displayName)")
print("Description: \(product.description)")
print("Price: \(product.displayPrice)")
print("Subscription Type: \(product.type)")
// if let subscription = product.subscription {
// print("Subscription Duration: \(product.duration)")
// print("Intro Offer: \(subscription.introductoryOffer?.description ?? "None")")
// }
}
} catch {
print("❌ Failed to fetch products: \(error)")
}
}
}
extension IAPManager {
func observeTransactions() {
Task.detached(priority: .background) {
for await result in Transaction.updates {
switch result {
case .verified(let transaction):
print("🔄 Transaction updated: \(transaction.productID)")
// Finish transaction to mark as delivered
await transaction.finish()
case .unverified(_, let error):
print("⚠️ Transaction unverified: \(error.localizedDescription)")
}
}
}
}
// MARK: - Purchase Product
func purchase(product: Product) async {
do {
let result = try await product.purchase()
switch result {
case .success(let verification):
// Check if transaction is verified
switch verification {
case .verified(let transaction):
print("✅ Purchase successful!")
print("Product ID: \(transaction.productID)")
print("Transaction ID: \(transaction.id)")
print("Purchase Date: \(transaction.purchaseDate)")
// Finish transaction to update entitlements
await transaction.finish()
case .unverified(_, let error):
print("⚠️ Purchase verification failed: \(error.localizedDescription)")
}
case .userCancelled:
print("❌ Purchase cancelled by user")
case .pending:
print("⏳ Purchase is pending...")
@unknown default:
print("❓ Unknown purchase result")
}
} catch {
print("❌ Purchase failed with error: \(error.localizedDescription)")
}
}
}
- I triggered the function from my Viewcontroller:
// in viewDidLoad
Task {
await IAPManager.shared.fetchProducts()
}
// in button action
Task {
// Wait until products are fetched
while IAPManager.shared.products.isEmpty {
try? await Task.sleep(nanoseconds: 200_000_000) // 0.2s
}
guard let product = IAPManager.shared.products.first else {
print("❌ No product available")
return
}
print("Product to be purchased \(product)")
await IAPManager.shared.purchase(product: product)
}
- In App Delegate:
// in applicationDidFinishLaunching
IAPManager.shared.observeTransactions()
Problem: Although the product is getting fetched correctly, but while purchasing it shows me the error in terminal as:
