TipJar

Simple app showing how to implement a Tip jar with RevenueCat and SwiftUI

Requirements
Install RevenueCat package
Create In-App Purchases in App Store Connect
Configure project in RevenueCat
Configure App Key
Test application

Requirements

RevenueCat Account https://www.revenuecat.com
Apple Developer Account https://developer.apple.com

Step 1

Install RevenueCat package in your project

Go to File > Add Packages > Search for https://github.com/RevenueCat/purchases-ios.git

Select RevenueCat in the list

Step 2

Create project in App Store Connect

Create In-App Purchases
Go to Features > In-App Purchases and add a new one

Once inside choose Availability, Price, Localization and very important Review information with an image and save it. Create as many In-App purchases as you want

NOTE: If your In-App purchase has the status of Missing Metadata, it means something is missing and this could prevent RevenueCat from getting it

Create an App-Specific Shared Secret

Go to General > App Information under App-Specific Shared Secret click on Manage

And then in Generate

This key will be used when we configure the RevenueCat project

Step 3

Create project in RevenueCat

Select App Store app, App Bundle ID is the one you find in your Xcode project under Signing & Capabilities and then set the previously created secret key in your project from App Store Connect

Create Products

Go to Products and create a new one

Identifier should be the same as the Product ID in the App Store Connect

Create a Product for each In-App purchase you have created

Create Offerings

Identifier and description could be anything

Click on your new Offering and create a New Package

You can select a default identifier depending on the recurrence of your In-App purchase but in this case as we are creating a tip jar, I will put a custom identifier with the title of each In-App purchase

After creating all the necessary Packages

You will need to assign your Products to each Package

Select a Package and click on Attach

Select the corresponding Product

Now you will be able to see all the Products attached to your Packages

Create an Entitlement

Click on your created Entitlement

And Attach all your Products

Step 4

Configure your RevenueCat public key in your Xcode project

Go to API Keys in RevenueCat and copy the Public app-specific API keys

And then paste that key into you app

You can import the IAPManager.swift and the TipJarView.swift into your project to validate your In-App Purchases

Note: Remember to inject the SuscriptionsManager into your main view

  @StateObject var subscriptionManager = IAPManager()

  var body: some Scene {
      WindowGroup {
          ContentView()
              .environmentObject(subscriptionManager)
      }
  }
  init() {
      Purchases.logLevel = .debug
      Purchases.configure(withAPIKey: "PublicKeyFromRevenueCat") //Public key from RevenueCat project
  }

Step 5

Testing your app

If you run your app, you should be able to see all your In-App Purchases that are in status Ready to Submit in the App Store Connect

And that is it, to test your In-App Purchases you have to create a Sandbox Tester in App Store Connect and toggle to Sandbox Data in RevenueCat
