为 iOS 运行 flutter 项目时出现错误

Question

I am getting below output error while running the flutter project in iOS.

This error is related to Cocoapods.

Please guide me how should I resolve it.

Earlier error was related to iOS version 8.0 which I upgraded to 9.0, after that I am facing this issue and getting error while running for iOS

Answer 1

You can try to uncomment platform:ios, '9.0' by removing # in your podfile. Then re-install pods.
