You should add GameKit.framework to your build

Hi liortal,

thanks for the response! The problem here is that previously the build worked without a problem and suddenly it stopped working.

Anyway, how can I add the GameKit Framework to the cloud build?

Thanks!

I am not familiar with the history of your project, so i can’t say why it stopped working.

You have 2 choices i can think of to add this:

  • If you already have iOS plugins in your project (e.g: a .framework file, or any other iOS native code file), you should be able to set it up through this file’s plugin inspector. When you select that file, the inspector will show you different settings for that plugin. In that inspector, you can select additional frameworks that the plugin requires. You can add GameKit (check its checkbox).
  • Another option is to create a custom editor script that uses the Xcode API to modify the built Xcode project to add GameKit. See this thread for info on how to do it (very simple): UCB Demos - Unity Services - Unity Discussions

Hi liortal,

It is working now, for some reason I had to add all frameworks manually to unity cloud build (following your suggestion on step 2)

Thank you SO much! :slight_smile:
