Flutter app can run in Xcode and not in Android Studio

Question

As the title suggests, I simply cannot run my flutter app on Android Studio (using the IOS simulator). Somehow, if I run and fix all Xcode errors in Xcode itself, I am able to run it. However, when I try to run it in android studio a second later, many errors appear coming from the IOS build. There is no specific error log as the warning are always different. Here are some of the causes that I am suspicious of:

I updated to Xcode 13, which has a new build system.
I updated to a new Flutter version.
I updated to a new Android Studio Version (Arctic Fox).

I have tried many things, including:

Pod deintegrate** & pod install
Cleaning and running
Restarting the computer
Legacy build system

There are just too many things I have tried, I only remember half of them. Here is my latest error log when trying to build from Android Studio:

EDIT-------- Here is my most recent error log:

Could not build the application for the simulator.
Error launching application on iPhone 12 Pro.

Apple requires the use Xcode to run on iOS simulator or device. I could be wrong, but that is my understanding and my take of how the [Flutter website describes testing for iOS](https://flutter.dev/docs/get-started/install/macos). — daddygames, Sep 29 '21 at 13:52
@daddygames Android Studio and Flutter are prepared for simulation of IOS apps. I have already done it a thousand times. Android Studio takes the Xcode (IOS) module and runs it. However, after some updates, something is wrong and I can't get to the bottom of it. As if the errors only occur in Android Studio and not Xcode, which doesn't make sense since they are both running the same thing. — Tomas Ward, Sep 29 '21 at 13:59

The only truly important error was the following:

ld: building for iOS Simulator, but linking in dylib built for iOS, file '/Users/tomasward/Desktop/Fredi/ios/Pods/TwitterKit/iOS/TwitterKit.framework/TwitterKit' for architecture arm64

What is it actually saying? arm64 is an architecture used for physical devices, not for the simulator. So, I was trying to simulate an invalid architecture in a virtual device. I had read that I needed to exclude arm64 from my build settings in my target project. However, the missing step was to also exclude it from pods as follows:

Voilá!

The "pod install" command will continuously override these settings.
