Use Alamofire & SwiftyJSON to POST to a JSON API, retry every second unless cancelled or successful

1.postToIp.swift

import Alamofire

class Something {

    var postCancelled: Bool = false

    func postToIp(ip: String) {

        let parameters = [
            "a": "value 1",
            "b": "value 2",
        ]
        
        Alamofire.request(.POST, "http://\(ip)/api", parameters: parameters, encoding: .JSON)
            .responseJSON({ (_, _, jsondata, _) in
                let jsondata = JSON(jsondata!) // this is SwiftyJSON 
                if let success = jsondata["success"].dictionary {
                    println("test succeeded")
                } else {
                    if (!self.postCancelled) {
                        println("retry after 1 second")
                        let delayInSeconds = 1.0
                        let delay = dispatch_time(DISPATCH_TIME_NOW, Int64(delayInSeconds * Double(NSEC_PER_SEC)))
                        dispatch_after(delay, dispatch_get_main_queue()) {
                            println("retrying...")
                            self.postToIp(ip)
                        }
                    }
                }
            })
    }
}

I used http://www.raywenderlich.com/85080/beginning-alamofire-tutorial to add the Alamofire framework.

For SwiftyJSON I just dropped the .swift file in my project.
