mxcl/PromiseKit: Promises for Swift & ObjC.

Promises simplify asynchronous programming, freeing you up to focus on the more important things. They are easy to learn, easy to master and result in clearer, more readable code. Your co-workers will thank you.

UIApplication.shared.isNetworkActivityIndicatorVisible = true

let fetchImage = URLSession.shared.dataTask(.promise, with: url).compactMap{ UIImage(data: $0.data) }
let fetchLocation = CLLocationManager.requestLocation().lastValue

firstly {
    when(fulfilled: fetchImage, fetchLocation)
}.done { image, location in
    self.imageView.image = image
    self.label.text = "\(location)"
}.ensure {
    UIApplication.shared.isNetworkActivityIndicatorVisible = false
}.catch { error in
    self.show(UIAlertController(for: error), sender: self)
}

PromiseKit is a thoughtful and complete implementation of promises for any platform that has a swiftc. It has excellent Objective-C bridging and delightful specializations for iOS, macOS, tvOS and watchOS. It is a top-100 pod used in many of the most popular apps in the world.

In your Podfile:

use_frameworks!

target "Change Me!" do
  pod "PromiseKit", "~> 8"
end

PromiseKit 8 supports recent Xcodes (13+). Some Podspecs were dropped as a result. Pull requests are welcome.

PromiseKit 6, 5 and 4 support Xcode 8.3, 9.x and 10.0; Swift 3.1, 3.2, 3.3, 3.4, 4.0, 4.1, 4.2, 4.3 and 5.0 (development snapshots); iOS, macOS, tvOS, watchOS, Linux and Android; CocoaPods, Carthage and SwiftPM; (CI Matrix).

For Carthage, SwiftPM, Accio, etc., or for instructions when using older Swifts or Xcodes, see our Installation Guide. We recommend Carthage or Accio.

As of Swift 5.5, the Swift language now offers support for built-in concurrency with async / await. See Async+ for a port of PromiseKit's most useful patterns to this new paradigm.

Promises are only as useful as the asynchronous tasks they represent. Thus, we have converted (almost) all of Apple’s APIs to promises. The default CocoaPod provides Promises and the extensions for Foundation and UIKit. The other extensions are available by specifying additional subspecs in your Podfile, e.g.:

pod "PromiseKit/MapKit"          # MKDirections().calculate().then { /*…*/ }
pod "PromiseKit/CoreLocation"    # CLLocationManager.requestLocation().then { /*…*/ }

All our extensions are separate repositories at the PromiseKit organization.

Then don’t have them:

pod "PromiseKit/CorePromise", "~> 8"

Note: Carthage installations come with no extensions by default.

Promise chains commonly start with a network operation. Thus, we offer extensions for URLSession:

// pod 'PromiseKit/Foundation'  # https://github.com/PromiseKit/Foundation

firstly {
    URLSession.shared.dataTask(.promise, with: try makeUrlRequest()).validate()
    // ^^ we provide `.validate()` so that eg. 404s get converted to errors
}.map {
    try JSONDecoder().decode(Foo.self, with: $0.data)
}.done { foo in
    //…
}.catch { error in
    //…
}

func makeUrlRequest() throws -> URLRequest {
    var rq = URLRequest(url: url)
    rq.httpMethod = "POST"
    rq.addValue("application/json", forHTTPHeaderField: "Content-Type")
    rq.addValue("application/json", forHTTPHeaderField: "Accept")
    rq.httpBody = try JSONEncoder().encode(obj)
    return rq
}

Support for Alamofire is welcome, please submit a PR.
