I am dealing with a problem whereas constructing my Flutter app for the iOS simulator. The construct fails with the error:
vbnet
Copy
Edit
Error (Xcode): Framework ‘Flutter’ not discovered
Error (Xcode): Linker command failed with exit code 1
I’ve tried the next steps:
Recreated the ios/ folder and cleared derived knowledge.
Ran flutter clear, reinstalled CocoaPods (pod deintegrate and pod set up).
Verified AppDelegate and framework paths in Xcode.
Ensured the deployment goal is ready to 14.0 within the Podfile.
Regardless of these efforts, the difficulty persists. I am utilizing the most recent Flutter SDK, Xcode, and macOS variations. Any steerage to resolve this is able to be enormously appreciated

Deleted derived knowledge utilizing rm -rf ~/Library/Developer/Xcode/DerivedData.
Recreated the ios/ folder.
Up to date CocoaPods and ensured all dependencies in pubspec.yaml are up-to-date.
Verified AppDelegate.swift and ensured Firebase setup (added FirebaseCore initialization in AppDelegate.swift).
Regardless of these efforts, the difficulty persists. Initially, I managed to resolve it by working these steps in sequence:
bash
Copy

flutter clear
rm -rf ios/Pods
rm -rf ios/.symlinks
rm -rf ios/Flutter/Flutter.framework
sudo gem set up cocoapods
pod repo replace
cd ios
pod set up
flutter improve
flutter pub get
cd ios
pod deintegrate
pod set up
rm -rf ~/Library/Developer/Xcode/DerivedData
flutter clear
flutter pub get
cd ios
pod set up
cd ..

This mounted the difficulty quickly. Nevertheless, after two days, I confronted errors in Firebase telephone authentication. I added FirebaseCore initialization in AppDelegate.swift, which resolved the Firebase error however reintroduced the "Framework 'Flutter' not discovered" error.
I’m looking for steerage to resolve this persistent problem as soon as and for all. Any insights or solutions could be enormously appreciated!
