Error:Unity to xcode; Undefined symbols for architecture arm64:

Right now, I am making an augmented reality with unity. And I tried building with x-code. But I got the following error. If you have a similar experience, please advise me. Mu Unity's build setting is ARM46

It's missing library.

In your Unity3D project, please make sure XR is enabled.

If you are using the latest version of Unity3D, you have to enable ARKit Build Settings in Project Settings. Meanwhile, in XR Plug-in Management(iOS), you have to toggle on the ARKit as Plug-in Providers.

and of course, don't forget to add camera usage description in build settings.
