    Workaround is to flutter run to a simulator, or open ios/Runner.xcworkspace in Xcode and deploy to a real iOS device from there.

    You need the ios-deploy 1.11.2 for the released version of iOS14. https://github.com/ios-control/ios-deploy/releases/tag/1.11.2

    Earlier betas of iOS14+Xcode12 worked with ios-deploy 1.11.0, but won't work with the final/GM versions.

    @DhavalRKansara You might do better opening a new bug. It appears you are using an old copy of ios-deploy since those lines were changed in https://github.com/ios-control/ios-deploy/pull/464/files

    if you have homebrew (you should)

    brew install --HEAD ios-deploy

    then flutter channel stable
    flutter upgrade
    flutter clean
    flutter run -d device

    You shouldn't need to run brew install --HEAD ios-deploy, it's distributed in Flutter.
