Here is a little different approach using asynchronous request. You can use synchronous approach this way too but since everyone above used synchronous request, I thought show asynchronous request instead. Another thing is it seems cleaner and easier this way.

    let JSONObject: [String : AnyObject] = [
        "name" : name,
        "address" : address,
        "phone": phoneNumber
    ]

    if NSJSONSerialization.isValidJSONObject(JSONObject) {
        var request: NSMutableURLRequest = NSMutableURLRequest()
        let url = "http://tendinsights.com/user"

        var err: NSError?

        request.URL = NSURL(string: url)
        request.HTTPMethod = "POST"
        request.cachePolicy = NSURLRequestCachePolicy.ReloadIgnoringLocalCacheData
        request.setValue("application/json", forHTTPHeaderField: "Content-Type")
        request.HTTPBody = NSJSONSerialization.dataWithJSONObject(JSONObject, options:  NSJSONWritingOptions(rawValue:0), error: &err)

        NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue()) {(response, data, error) -> Void in
            if error != nil {

                println("error")

            } else {

                println(response) 

            }
        }
    }
