Open Source SoftEther protocol Issue in Mobile App

Good day, This is a challenge for all the programmers out there, who can help resolve this issue, and if this issue is resolved, then this is going to be a celebration time :). We have been trying to resolve this issue but so far no luck, so thought to post here with this hope and wish that someone can help resolve this issue.

Please let me know, how long it will take and how much you will cost to resolve this issue.

See below and let me know if any of you can resolve this issue:

See this code: https://github.com/SoftEtherVPN/SoftEtherVPN_Stable

We need to compile or convert the softether client pack send/receive binary protocol and encryption to swift ios project like their client do for windows and linux. Softether actually not providing the implementation for ios. We have replicated the TLS connection but not able to make the handshake binary protocol and softether server terminates the TLS connection with following logs:

On the TCP Listener (Port 443), a Client (IP address 39.60.124.38, Host name "39.60.124.38", Port number 56504) has connected.

For the client (IP address: 39.60.124.38, host name: "39.60.124.38", port number: 56504), connection "CID-4992" has been created.

SSL communication for connection "CID-4992" has been started. The encryption algorithm name is "TLS_AES_256_GCM_SHA384".

Connection "CID-4992" terminated by the cause "A client which is non-SoftEther VPN software has connected to the port." (code 5).

Connection "CID-4992" has been terminated.
The connection with the client (IP address 39.60.124.38, Port number 56504) has been disconnected.

Basically, you need to convert the C files logic of softether client into swift files that will be implemented in iOS.
