I download https://developer.apple.com/documentation/networkextension/filtering_network_traffic example
Build OK and I saw extension loaded.
NEProvider.startSystemExtensionMode() was called.
But FilterDataProvider init did not called.
I tried to disable SIP also. it does not work
I saw some warning like
/Applications/SimpleFirewall.app/Contents/Library/SystemExtensions/com.example.apple-samplecode.SimpleFirewallML4HRHFY98.SimpleFirewallExtension.systemextension: entitlement com.apple.developer.endpoint-security.client not present or not true
