Error (Xcode): Framework 'smart_auth' not found

[canbi]

If you encounter this error while running the iOS simulator, I resolved it by following the steps and redownloading all the pods, which allowed me to successfully run it on the simulator again.

flutter clean
rm -Rf ios/Pods
rm -Rf ios/.symlinks
rm -Rf ios/Flutter/Flutter.framework
rm -Rf ios/Flutter/Flutter.podspec
flutter pub get
cd ios
pod install # (or on an M1+ mac: arch -x86_64 pod install)
cd ..
flutter build ios
flutter run
