PromiseKit Alamofire Extensions Build Status

This project adds promises to Alamofire.

This project supports Swift 3.1, 3.2, 4.0 and 4.1.

Usage

Alamofire.request("https://httpbin.org/get", method: .GET)
    .responseJSON().then { json, rsp in
        // 
    }.catch{ error in
        //
    }

Of course, the whole point in promises is composability, so:

func login() -> Promise<User> {
    let q = DispatchQueue.global()
    UIApplication.shared.isNetworkActivityIndicatorVisible = true

    return firstly { in
        Alamofire.request(url, method: .get).responseData()
    }.map(on: q) { data, rsp in
        convertToUser(data)
    }.ensure {
        UIApplication.shared.isNetworkActivityIndicatorVisible = false
    }
}

firstly {
    login()
}.done { user in
    //
}.catch { error in
   UIAlertController(/**/).show() 
}
