Thanks!

Thanks @kiichi! Here is modified for swift 3:

let payload = "payload={\"channel\": \"#dev\", \"username\": \"bot\", \"icon_emoji\":\":calling:\", \"text\": \"hello\"}"
    
    let data = payload.data(using: .utf8)!
    
    if let url = NSURL(string: "https://hooks.slack.com/services/(your slack incoming webhook url)")
    {
        let request = NSMutableURLRequest(url: url as URL)
        request.httpMethod = "POST"
        request.httpBody = data
        let session = URLSession.shared
        let task = session.dataTask(with: request as URLRequest){
            (data, response, error) -> Void in
            if error != nil {
                print("error")
            }
            else if data != nil {
                if let str = NSString(data: data!, encoding: String.Encoding.utf8.rawValue) {
                    print("\(str)")
                }
                else {
                    print("error")
                }
            }
        }
        task.resume()
    }
    else {
        print("url invalid")
    }
