A Swift Wrapper for libdispatch aka Grand Central Dispatch (GCD) Framework that supports method chaining.

Tired of this?

dispatch_async(dispatch_get_global_queue(QOS_CLASS_BACKGROUND, 0)) { () -> Void in
    for index in 1...UInt64.max{
        print(index)
    }
    dispatch_async(dispatch_get_main_queue(), { () -> Void in
        print("Back to main thread")
    })
}

With RunKit

Run.background { 
    for index in 1...UInt64.max{
        print(index)
    }
}.main { 
    print("Back to main thread")
}

Installation

Cocoapods

Add this to your Podfile

pod 'RunKit', '~> 1.0'

Carthage

Add this to your Cartfile

github "khoiln/RunKit"

Usage

Supported Queues:

Run.main {}
Run.userInteractive {}
Run.userInitiated {}
Run.utility {}
Run.background {}

Queues Chaining:

Run.main { 
    print("main queue")
}.background { 
    print("background queue")
}.userInitiated {
    print("userInitiated queue")
}.main { 
    print("Back to main thread")
}

Using Custom Queue:

let queue = dispatch_queue_create("queue1", DISPATCH_QUEUE_SERIAL)
Run.custom(queue: queue){
    print("User created Queue")
}

Store blocks reference for chaining

let longRunningBlock = Run.background{
    for index in 1...UInt64.max{
        print(index)
    }
}
longRunningBlock.main{
    print("Back to main thread")
}

You can also cancel a running process

longRunningBlock.cancel()

Or wait for it to finish

longRunningBlock.wait()
print("Continue..")
