Error when trying to run or build Flutter project for iOS

Question

So basically I can run other projects and I can run this one for Android but when I want to run it or build it for iOS I get the following error message. Also it's not project related issue, my co-worker can run it just fine. I tried every possible online solution, adding post install stuff to Podfile, tried changing to 'legacy build system' in Xcode but same error, tried reinstalling Pod, CocoaPods, even switched to beta. No idea what to do anymore.

Launching lib/main.dart on iPhone 11 Pro Max in debug mode...
 
Running pod install...                                             23.5s

Related to Flutter project - XCode build failed

First, verify that you are in flutter channel stable, and flutter upgrade

Then, what worked for me :

sudo gem uninstall cocoapods; 
sudo gem install cocoapods; 
flutter clean
flutter pub get
cd ios; pod install; cd ..;

Other commands that might help

cd ios; pod install --repo-update; cd ..;
//deactivate rvm
rvm use system

Other ideas :

• Delete the entire repo and git clone
• Delete Derived Data (check Google)
• Delete Podspec.lock and Gemfile.lock
