Question AR Core Extension doesn't work in IOS

I was testing an app using the Google Geospatial API.
On Android, it worked perfectly. But when I turn on the "IOS Support Enabled" in Project Settings -> ARCore Extensions, and play it, I am getting the following error "EntryPointNotFoundException"

full error message:

EntryPointNotFoundException: ArSession_create

The project is Google's Geospatial API Sample.

Did you try to add ARCore library to your xcode project?

 

No, is there anything else I need to do besides installing the package?
Do you mean AR Core SDK??

 

I solved it! I didn't know how to install the AR Core SDK so I fixed something related to Cocoapods and it worked!
To be precise, the "EntryPointNotFoundException" in the Unity Editor is still there, but it builds fine.
I apologize for my poor English and thank everyone who helped.
