Making it to the iOS

Using Unity 2021.3.3f1. It compiles for all and run (PC, MAC, Android, and iOS) But my main target is iOS
Used this https://learn.unity.com/tutorial/publishing-for-ios#5ecfa875edbc2a00231dbfa4 to make my way around compiling to iOS and loading it sussecfully into the XCODE.

Questions:
01- Dont have an phone I select Simulatior, and it shows the Simulator with the icon, it launches and closes inmediatelly, the error says:
Products/ReleaseForRunning-iphoneos/UnityFramework.framework/UnityFramework'
(mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64')),

02- I selected on the certificate etc the WIFI option since it will need to access internet, so simulator must get internet from the MAC right?

03-With NO phone, I need to be able to test it, and then for my customer he will just make the whole proccess again but on his AppleDeveloper account (im a hired guy), test it and uploaded to the store.

How do I manage to run it on Simulator on the MacBook Air ? What do i need to touch? Maybe im RT(Wrong)FM

Cheers
