Could not build the application for the simulator. Error launching application on iPhone 11.

I am using bumblebee version of android studio. I have tried pod deintegrated and pod install but still not working.

Thanks is advance.

Solution

You need upgrade packages according to your iOS deployment target & flutter sdk version.

Then try below steps.

1. Run flutter clean
2. Run flutter pub get
3. Remove xcode derived data - check this link
4. Remove Pods folder form project iOS folder.
5. Remove Podfile.lock file from project iOS folder.
6. Remove project.workspace file
7. Run again in iOS platform.
