Unity IAP iOS tvOS tutorial

Introduction

This is the second tutorial on Unity IAP. In the previous one, we talked about Android. Today, we are going to talk about iOS and tvOS. I am not going to repeat the topics that apply to both Android and iOS. You can refer to the first tutorial for things like creating a unity project, enabling analytics, importing the IAP plugin, using the demo app, modifying player settings. In this tutorial, I am going to focus on creating iOS provisioning profiles, using iTunes connect to upload a test app, defining IAP products, creating sandbox test accounts, debugging tvOS SSL using Charles proxy.

iTunes Connect Users

Unity Project

We just finished all the required setup. The next step is to import, configure, build and deploy the Unity IAP demo app to a device. Everything for iOS should be similar to Android which was explained in the previous article. Instead of exporting an APK, we export an Xcode project. Open it in Xcode then build it to the device. You should have everything properly configured right after you export from Unity. If things do not work, pay attention to the following

• Make sure the bundle ID that you entered in Unity player settings is correct and matches that on iTunes.

• Make sure your are selecting the right team.

• If you have not downloaded all profiles (Xcode, preferences, accounts, etc) as we explained earlier, please do so.
• For tvOS, though Unity has to take care of this, if the store kit library is not included, add it manually.
