get IP address

[Jdgmx]

I'm getting a little lost in the NE documentation.
What would be the recommended way to get the IP address that the device gets when connected to the VPN?
Thanks.

I'm successfully communicating with the network extension in the method
func handleAppMessage(_ messageData: Data, completionHandler: ((Data?) -> Void)?)

But if adapter is my OpenVPNAdapter instance, then in adapter.connectionInformation?.clientIP I'm getting a nil value.
What am I missing?
