1 Cannot find "xcodebuild". Xcode 11.0 or greater is required to develop for iOS. Could not build the precompiled application for the device.
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
如果路径不对，可以找到Xcode，拉去路径
2 flutter model下面没有 .ios 文件夹
flutter create --template module my_flutter
