Need description for TunnelConfiguration parameter in IOS

I looked into Wireguard VPN integration in the code where, I found a structure which has following detail for VPN configuration.

struct TunnelConfig {  
var privateKey: String  
var gatewayId: String  
var gatewayIpv4: String  
var gatewayIpv6: String  
var gatewayPort: String  
var vip4: String  
var vip6: String  
}

can you please share some detail description for every variable usage description?  
Because, the basic WireGuard configuration has following things:

[Interface]  
Address = x.x.x.x/xx  
PrivateKey = xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx  
DNS = x.x.x.x

[Peer]  
PublicKey = xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx  
Endpoint = x.x.x.x:xxxx  
AllowedIPs = x.x.x.x/x

Thanks.
