Sample request model that can be converted to a MutableURLRequest

request.swift

class Request {
    
    var url: String
    var requestType: RequestType
    var body: NSData?
    var headers: Dictionary<String, String>?
    
    init(url: String, requestType: RequestType, body: NSData?, headers: Dictionary<String, String>?) {
        self.url = url
        self.requestType = requestType
        
        if body != nil {
            self.body = body!
        }
        
        if headers != nil {
            self.headers = headers!
        }

    }
    
    func toMutableURLRequest() -> NSMutableURLRequest {
        println("Setting up URL: \(url)")
        var request = NSMutableURLRequest(URL: NSURL(string: url)!)
        
        println("Setting up request type: \(requestType.rawValue)")
        request.HTTPMethod = requestType.rawValue
        
        request.HTTPBody = body
        
        if let newHeaders = headers {
            for (key, value) in newHeaders {
                request.addValue(value, forHTTPHeaderField: key)
            }
        }
        
        return request
    }
