I can build the SimpleFirewall application (https://developer.apple.com/documentation/networkextension/filtering_network_traffic ) using xcode: After I run the application, seems can't block any traffic.

I find there is some logs from network extension process:

networkd_settings_read_from_file Sandbox is preventing this process from reading networkd settings file at "/Library/Preferences/com.apple.networkd.plist", please add an exception.

Any step I am missing ?

It could just be how you are running the application and network system extension. When you build the application, are you able to move it to the application directory and then execute the container app? Have you also changed the bundle identifiers on the container app and the network system extension to be compatible with your developer account?
