Dispatch

Note:

Dispatch requires swift 3.0. Use version 1.0.0 for swift 2.3 or version 0.9.8 for swift 2.2.

Installation

CocoaPods

Dispatch is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'Dispatch'

Carthage

---

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

To integrate Dispatch into your Xcode project using Carthage, specify it in your Cartfile:

github "Swiftification/Dispatch"

Run carthage update to fetch the Dispatch library and drag into your Xcode project.

And then simply

import DispatchFramework

And your good to go!

Manually

1. Download and drop Dispatch.swift anywhere you like in your project.
2. That's it.

Usage

Basic

Dispatch.async(dispatch_get_main_queue()) {
  //Code to be run on the main thread
}

Or using the helpers provided by Dispatch.Queue enum

Dispatch.async(Queue.main) {
  //Code to be run on the main thread
}

Or using the overloaded method to run on the main thread

Dispatch.async {
  //Code to be run on the main thread
}

Types of Dispatch

Async

Dispatch.async(Queue.main) {
  //Code to be run on the main thread
}

Sync

let someCustomQueue = dispatch_queue_create("custom.queue.dispatch", DISPATCH_QUEUE_CONCURRENT)
Dispatch.sync(someCustomQueue) {
  //Code to be synchronously on someCustomQueue
}

After

Dispatch.after(1.0, queue: Queue.main) {
  //Code to be run on the main thread after 1 second
}

Or using the overloaded method to run on the main thread

Dispatch.after(1.0) {
  //Code to be run on the main thread after 1 second
}

Once

let token : dispatch_once_t
Dispatch.once(&token) {
  //Code to be run only once in App lifetime
}

Queue Helpers

Main queue

let mainQueue = Queue.main 

Custom queue

let customConcurrentQueue = Queue.custom("custom.concurrent.queue.dispatch", Queue.Atribute.concurrent)
let customSerialQueue = Queue.custom("custom.serial.queue.dispatch", Queue.Atribute.serial)

Global queues

let priority = 0 // or you use one of the Global priorities (ex: Queue.Priority.UserInteractive)
let globalQueue = Queue.global(priority)

// For comodity there are helpers for getting the Global queues

let globalUserInteractiveQueue = Queue.globalUserInteractive
let globalUserInitiatedQueue = Queue.globalUserInitiated
let globalUtilityQueue = Queue.globalUtility
let globalBackgroundQueue = Queue.globalBackground
