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

Solution

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

Sorry it didn't helped me as of now, I did as you said, run flutter clean and then tried to install the app and the same error I got again

Sometimes, flutter clean is not enough itself. You can try to delete ios/Podfile.lock, ios/Pods, ios/Flutter/App.Framework too.

[Admin]

you mean ios/Flutter/Flutter.Framework ??

[Akif]

Yes, you're right! Delete ios/Flutter/Flutter.Framework too.
