Or you can install it with Carthage:

github "intelygenz/Kommander-iOS"

Or install it with Swift Package Manager:

dependencies: [
    .package(url: "https://github.com/intelygenz/Kommander-iOS.git")
]

🐒 Usage

Making, executing, cancelling and retrying Kommands:

Kommander().make {
    // Your code here
}.execute()

Kommander().make {
    // Your code here
}.execute(after: .seconds(2))

Kommander().make {
    return "Your string"
}.success { yourString in
    print(yourString)
}.execute()

Kommander().make {
    throw CocoaError(.featureUnsupported)
}.error { error in
    print(String(describing: error!))
}.execute()

Specify Error type:

Kommander().make {
    throw MyError.error
}.error(MyError.self) { error in
    // error is MyError type.
}.execute()

Retry after cancellation:

let kommand = Kommander().make { () -> Any? in
    // Your code here
}.success { result in
    // Your success handling here
}.error { error in
    // Your error handling here
}.execute()

kommand.cancel()

kommand.retry()

Retry after failure:

let kommand = Kommander().make { () -> Any? in
    // Your code here
}.error { error in
    // Your error handling here
}.retry { error, executionCount in
    return executionCount < 2
}.execute()

Creating Kommanders:

Kommander(deliverer: Dispatcher = .current, executor: Dispatcher = .default)

Kommander(deliverer: Dispatcher = .current, name: String, qos: QualityOfService = .default, maxConcurrentOperations: Int = .default)

Shortcuts:

Kommander.main

Kommander.current

Kommander.default

Kommander.userInteractive

Kommander.userInitiated

Kommander.utility

Kommander.background

Creating Dispatchers:

CurrentDispatcher()

MainDispatcher()

Dispatcher(name: String, qos: QualityOfService = .default, maxConcurrentOperations: Int = .default)

Shortcuts:

Dispatcher.main

Dispatcher.current

Dispatcher.default

Dispatcher.userInteractive

Dispatcher.userInitiated

Dispatcher.utility

Dispatcher.background
