Simple helper classes which will reduce the complexity for using concurrent methods in Swift.

Installation

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

pod "ROConcurrency"

How to use

Barrier

With the following class Barrier you can define a set of tasks which are all executed asynchrounisly. The barrier will keep track of the executed tasks and if all tasks are finished you can define an afterTask which will be executed after all the other ones are finished.

Creating of the tasks

var task_one = Task {
    sleep(3)
    println("Task one is doing some stuff..")
}

var task_two = Task {
    println("Task two is doing some stuff..")
}

var task_third = Task {
    println("Task three is doing some stuff..")
}

var afterTask = Task {
    println("I should get executed at the end of all the other requests")
}

Then the barrier is created with the following line of code:

var barrier = Barrier(tasks: [task_one, task_two, task_third], afterTask:afterTask)

If you want to activate the verbose logging of the task execution you can set the param verbose to true (Default is false).

var barrier = Barrier(tasks: [task_one, task_two, task_third], afterTask:afterTask, verbose:true)

The tasks can be started with the method startTasks

barrier.startTasks()

BarrierComplex

Often you already have asynchronous tasks with the method above its not possible to notify the Barrier that an asynchronous task has finished. So that’s where the TaskComplex and BarrierComplex class comes in. In the TaskComplex block you can pack an already asynchrously method and add the call of finished() at the end of the execution of the asynchronous block. The rest is exactly the same concept as in the Barrier class above.

        var taskDownload = TaskComplex { (finished) -> () in
            // Do something asynchronously and then at the end call the finished block to notify the barrier that it's finished
            finished()
        }

        var taskCompress = TaskComplex { (finished) -> () in
            // Do something else
            finished()
        }

        var notifiyEveryoneAtTheEnd = TaskComplex { (finished) -> () in
            // Notify everyone
            finished()
        }

        var barrierComplex = BarrierComplex(tasks: [taskDownload, taskCompress], afterTask: notifiyEveryoneAtTheEnd, verbose: true)

        barrierComplex.startTasks()
