Simplest way to write an async client server (like with that python library)

Dear Sirs,

I have a question about swift 5. With this release, is coming a library for the async programming?

I just want to write a very simple app like this in python (in python I have a third party library called AsyncIO, but maybe something like that could exist for swift):

TCP ECHO CLIENT:

import asyncio 

async def tcp_echo_client(message, loop): 
     reader, writer = await asyncio.open_connection('127.0.0.1', 8888, loop=loop) 
     print('Send: %r' % message)
     writer.write(message.encode())

      data = await reader.read(100)
      print('Received: %r' % data.decode())
 print('Close the socket') 
writer.close() 

message = 'Hello World!' 
loop = asyncio.get_event_loop()
loop.run_until_complete(tcp_echo_client(message, loop)) 
loop.close()

TCP ECHO SERVER:

import asyncio 

async def handle_echo(reader, writer): 
     data = await reader.read(100) 
     message = data.decode() 
     addr = writer.get_extra_info('peername') 
     print("Received %r from %r" % (message, addr))

 print("Send: %r" % message)
 writer.write(data) 
 await writer.drain() 

print("Close the client socket") 
writer.close() 

loop = asyncio.get_event_loop() 
coro = asyncio.start_server(handle_echo, '127.0.0.1', 8888, loop=loop) 

server = loop.run_until_complete(coro)
 # Serve requests until Ctrl+C is pressed 

print('Serving on {}'.format(server.sockets[0].getsockname()))
 try: 
     loop.run_forever() 
     except KeyboardInterrupt: 
          pass 
# Close the server 
server.close() 
loop.run_until_complete(server.wait_closed()) 
loop.close()

There is a way to write something simple like that in swift 5?
