importing swift file to obj-c
Question: Okay, this one is too much for me. I'm trying to import manually file from
socket-io which are written in swift, to my project who is fully written in
obj-c.

I have read the doc from [Swift and
obj-c](https://developer.apple.com/library/ios/documentation/Swift/Conceptual/BuildingCocoaApps/MixandMatch.html#//apple_ref/doc/uid/TP40014216-CH10-ID138),
but that's not really helpful at all. And from [socket-
io](https://github.com/socketio/socket.io-client-swift), same thing. All it
says is to download the github project, import the "source" folder to my obj-c
project, and then follow the instruction from Apple doc which to my opinion
are definitively not clear at all.

My question is: what is the concept of swift module? Because I definitively
didn't found what conceptually is a module, and how to build it from a folder
of swift file, even if I think it is a collection of swift class, but with
Apple, I'm not even sure of this.

my project is structured like this:

    
    
    .
    +-- projectName
    +-- Source
    |   +-- SockectFile_0.swift
    |   +-- SockectFile_1.swift
    |   +-- SockectFile_2.swift
    |   +-- SockectFile_3.swift
    
    +-- ViewController
    |   +-- viewController_0.h
    |   +-- viewController_0.m
    

Then how to import the whole "Source" folder with all this files inside to my
viewController_0.m ? I don't have even any idea how to compile it as a module.
Or if it is the right way to do it. Like I said, I'm in a confused state right
now.

Thanks for the answers in advance.

**Note** After further research, I have give it up. What I did is compile the
entire swift project alone and import it as framework. But of course, it is
too much for Xcode to handle the framework as a fat binary. Sorry if I look
gross, but I don't understand why Xcode is a sooooooooooo bad IDE tool. For
info, it took me approximatively 1 minute to import socketIO in my python
project where it took me 3 hours with Xcode with the source code, and I just
dodged the problem because what I did is the binary solution (Xcode is even
not good at making a simple fat binary by itself. Where it took 3 lines of
script to implement). I really hate.


Answer: # Making Swift Module

You have to follow these steps Goto Build Setting > Search = Defines Module to
**YES** then > Search product module name and give name for your Module there

Your Can use your Module Like `@import MQTTKit;`
