SwiftyStoreKit.completeTransactions(): A critical step for in-app purchase success

SwiftyStoreKit is a popular third-party library that simplifies in-app purchase implementation in Swift apps. It provides a high-level abstraction over the StoreKit framework, making it easier to manage transactions, products, and receipts.

One critical step in using SwiftyStoreKit is to call the completeTransactions() method when the app launches. This method finalizes any pending in-app purchase transactions, ensuring that users have access to the content they purchased and that all transactions are properly processed.

Why you need to call SwiftyStoreKit.completeTransactions() when the app launches

There are several reasons why you need to call completeTransactions() when the app launches:

• To ensure that users have access to the content they purchased as soon as possible.
• To prevent crashes and errors caused by unfinished transactions.
• To improve the overall user experience by streamlining the in-app purchase process.

How to call SwiftyStoreKit.completeTransactions() when the app launches

The best place to call completeTransactions() is in the app delegate's didFinishLaunchingWithOptions() method. This method is called when the app launches, so it is a good place to ensure that all pending transactions are finalized.

Here is an example of how to call completeTransactions() in the app delegate's didFinishLaunchingWithOptions() method:

import UIKit
import SwiftyStoreKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

        // Complete any pending in-app purchase transactions
        SwiftyStoreKit.completeTransactions(atomically: true) { purchases in
            // Handle the completed transactions
        }

        // Return true to indicate that the app is ready to launch
        return true
    }
}

Benefits of calling SwiftyStoreKit.completeTransactions() when the app launches

Calling completeTransactions() when the app launches has a number of benefits, including:

• Improved user experience: Users have access to the content they purchased as soon as possible, without having to wait for transactions to finalize.
• Reduced crashes and errors: Unfinished transactions can cause crashes and errors, so calling completeTransactions() helps to prevent these issues.
• Increased in-app purchase revenue: By streamlining the in-app purchase process and improving the user experience, calling completeTransactions() can lead to increased in-app purchase revenue.
