ParallelSwift

Wrapper to simplify parallel execution of methods. With three different excution modes. Plus optional timeout to prevent locking app, and possibility to shuffle queue order. Made purely in Swift. See Test folder for usege examples.

Install

ParallelSwift is available through CocoaPods. and via Swift Package Manager.

Cocoapods

To install it, simply add the following line to your Podfile:

pod 'ParallelSwift'

Swift Package Manager

Add link to this repository in Xcode to projects Swift Packages. https://github.com/jvk75/ParallelSwift

Manually

Add Sources folder to your project

Modes

All

Execution closure is executed after all phase closures are finnished.

Any

Execution closure is executed after first phase closure is finnished.

None

Execution closure is executed immediately after phases are started.

Usage

Add methods to be executed as closure with addPhase (one by one) or with addPhases (as array). Both methods take one parameter that defines where the phase/s are executed (.main or .background (default)) Once excute is called all phases are launch simultaneusly (in parallel).

Methods will mark themself finnished a by calling input closure (e.g. done in the example) .

Execution completion closure is always executed in main thread. See modes.

    let p = ParallelSwift()

    p.addPhase { done in
       print("1")
       done()
    }
    p.addPhase { done in
       print("2")
       done()
    }
    p.addPhase(.main) { done in
        print("3")
        done()
    }
    p.execute(.all) {
        print("all done")
    }

See tests for more use cases.

Parameters

timeout : Time in seconds after which execute completion is called even if phases are still running. Default: 0 (no timeout)

shufflePhases: If true the order which phases are put to operation queue is randomized. Default: false
