`Launching lib/main.dart on iPhone 8 in debug mode...
Running pod install...
Running Xcode build...
Xcode build done. 15,0s
Failed to build iOS app
Error output from Xcode build:

Could not build the application for the simulator.

Can anybody help me?

Thanks.

Same problem here!

I am having the same issue... Is the repo being maintained? Seems like as soon as this package is added... my whole project breaks

[guilhermefilippo]

Hello @shaun0203 @Noninus

Add on pubspec.yaml

  flutter_card_io:
    git:
      url: git://github.com/ogestor/flutter_card_io.git

OR

  flutter_card_io:
    git:
      url: git://github.com/procedurallygenerated/flutter_card_io.git

This repository is working to me.
