Flutterfire: [cloud_firestore] iOS build failed

[NoahVersace]

Describe the bug
After adding cloud_firestore: any to pubspec and launching it, Flutter fails to build the IOS App and outputs the following:

Launching lib/main.dart on iPhone 8 in debug mode...
Running pod install...
Xcode build done.                                           50.8s
Failed to build iOS app
Exited (sigterm)
Could not build the application for the simulator.
Error launching application on iPhone 8.

To Reproduce
Steps to reproduce the behavior:

1. Run "flutter create (projectname)"
2. Open pubspec.yaml
3. Add "cloud_firestore: any" to dependencies
4. flutter pub get
5. Run "flutter run"
6. Get Error Message

Expected behavior
I expected it, to build the ios App successfully and then open the app in the Xcode Simulator.

Additional context
I tried different versions of cloud_firestore, Flutter and Cocoapods.
And when I put the GoogleService-Info.plist in the Runner/Runner folder and run it i get the following Error

Xcode's output:

The problem was gRPC itself. It probably failed cloning all the files to the cached version of gRPC-C++. I deleted the cached version and now it works.

Hey @NoahVersace , I faced the similar issues. Could you share more about where to deleted the cached version of gRPC-C++ ?

Thanks a lot !

Hey @shingsoso @YazeedAlKhalaf

What I did is:

1. Open terminal
2. Enter cd /Users/yourusername/Library/Caches/CocoaPods/Pods/Release/
3. Enter open .
4. Delete gRPC-C++
5. Go back to your flutter project, navigate in to the ios/Pods folder and delete gRPC-C++
6. Run your flutter app

Cocoapods will then detect, when trying to install the gRPC-C++ Pod, that there is no cached version and clone it again from its repository.

I hope this helps!

Thanks a lot, man! You literally saved hours of refactoring the project!

I really appreciate it, btw this is the project I am talking about. It is a flutter chatting app called "beast". Under development.
