Take a look at their respective code files, RazeFaceProducts.swift and IAPHelper.swift. Notice that MasterViewController is using an object called RazeFaceProducts.store of type IAPHelper to do the heavy lifting. Purchases are stored as an array of SKProduct objects. ![]() This class displays the table view which will contain a list of available IAPs. The main view controller is in MasterViewController.swift. Head over to Xcode to take a quick look at the code. If you delete and reinstall the app, the Restore button will reinstate any previously purchased RazeFaces. ![]() Upon finishing this tutorial, there will be a list of RazeFaces listed in the table view which you’ll be able to buy. The answer is: Not a lot! You’ll see an empty table view, with a single Restore button in the navigation bar, which will be hooked up later to restore purchases. Build and run to see what it does so far. In this in-app purchase tutorial, you’ll build a small app called “RazeFaces”, which allows users to buy a “RazeFace”, which is a neat illustration commonly used on this site for books and videos.ĭownload the materials using the link at the top and open the starter project in Xcode. You’ll also need a paid developer account, with access to both the iOS Developer Center and App Store Connect. If these are unfamiliar topics, then check out our range of Swift tutorials before getting started. You’ll need to be familiar with basic Swift and iOS programming concepts. In this in-app purchase tutorial, you’ll leverage IAPs to unlock extra content embedded in an app. Following the initial release of an app, new paid content can be added to the same app instead of having to develop a brand new app to earn more money.You can display advertisements to the user in a free app with an option to remove them by purchasing an IAP.If users enjoy the app, then they can purchase more content or functionality later. Free apps will typically get many more downloads than paid apps. An app can be offered for free, which makes it a no-brainer download for most people.Some users are willing to spend a lot more on extra content or features. ![]() It’s an extra way to earn money, in addition to simply selling the app for a fee upfront.Implementing IAPs is particularly compelling for several reasons: One of the great things about building iOS apps is that you have lots of choices when it comes to monetizing your app: plain vanilla paid apps, free apps supported by ads, or even apps that support in-app purchases.Īn in-app purchase (or IAP) allows developers to charge users for specific functionality or content while using an app. Get started with in-app purchases to grow app revenue!
