Unable to resolve reference 'UnityEditor.iOS.Extensions.Xcode'. Is the assembly missing or incompatible with the current platform? How to fix

It's been a while since I last updated a past project, and a new error appears during the plugin update process.

Unable to resolve reference 'UnityEditor.iOS.Extensions.Xcode'. Is the assembly missing or incompatible with the current platform?

When developing for Android on Windows.. why an iOS issue? After searching, I found that when using SDKs like Firebase, you must install the iOS modules in the Unity Editor even when developing in a Windows environment.

According to the solution, you need to add iOS Build Support via Add Module in Unity Hub.

The fix was easy, but the reason seems a bit frustrating.

It seems like unnecessary size is increasing overall..
