Async

A lightweight wrapper around Grand Central Dispatch

Async makes it easy for you to chain operations together that should run on different threads.

Usage

You have two ways of using Async: You could use .async(...) and .then(...) like this:

Async.async(QOS: .Background, block: {
    print("Performing Task 1")    
}).then(after: 3, QOS: .Main) { 
    print("Performing Task 2")
})

Or by using .main() like this:

Async.main(block: {
    print("Performing Task 1") 
}).background(after: 3, block: {
    print("Performing Task 2") 
})

Both ways use the same mechanics internally so you can chose the syntax you like better.

In any case, you can specify a delay (in seconds) after which the block will be executed. The delay parameter is optional and nil (=0) by default.

You can find examples in the Playground file. Please feel free to play around with it :)

##Installation Just download the Async.swift file and you are ready to go.

I am also working on support for the Swift Package Manager.

##More Words I wrote a few lines about this project on my blog. Please let me know if you have any comments ☺️
