Echo is a simple way to create an event loop and use GCD in Swift for Linux and OSX

How to use?

Using Echo is simple, to start the main run loop, just call:

Echo.beginEventLoop()

or

Echo.begin()

When you want to exit the loop, just call exit

Echo.exit()

How to use GCD?

Using GCD is the same as with Mac OS X (With limited current features)

main.swift

import Echo

dispatch_async(dispatch_get_global_queue(0, 0)) {
    for i in 0 ..< 1000 {
        dispatch_async(dispatch_get_main_queue()) {
            print(i)
        }
    }

    dispatch_async(dispatch_get_main_queue()) {
        Echo.exit()
    }
}

Echo.begin()

The above code snippet will print all the numbers on the main loop whilst looping in the global queue.

What is it used for?

• Blackfish

• Orca (Coming soon...)

Is that it?

Yep, it's that simple.

Please feel free to fork and extend to the rest of GCD's functions for Linux
