pod 'Dispatch'

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
