Declare enum Router Alamofire swift 3.0 - swift

Question

I'm currently using cocoapods 1.1.0.rc.2. I've installed the Alamofire pod. With version 1.1.0.rc.2 it should work with swift 3.0.
However I'm trying to declare the following enum
enum Router: URLRequestConvertible {
static let baseURLString = "https://api.instagram.com"
static let clientID = "myID"
static let redirectURI = "http://www.example.com/"
static let clientSecret = "mySecret"
case PopularPhotos(String, String)
case requestOauthCode
static func requestAccessTokenURLStringAndParms(code: String) -> (URLString: String, Params: [String: AnyObject]) {
let params = ["client_id": Router.clientID, "client_secret": Router.clientSecret, "grant_type": "authorization_code", "redirect_uri": Router.redirectURI, "code": code]
let pathString = "/oauth/access_token"
let urlString = Instagram.Router.baseURLString + pathString
return (urlString, params as [String : AnyObject])
}
// MARK: URLRequestConvertible
var URLRequest: NSMutableURLRequest {
let result: (path: String, parameters: [String: AnyObject]?) = {
switch self {
case .PopularPhotos (let userID, let accessToken):
let params = ["access_token": accessToken]
let pathString = "/v1/users/" + userID + "/media/recent"
return (pathString, params as [String : AnyObject]?)
case .requestOauthCode:
let pathString = "/oauth/authorize/?client_id=" + Router.clientID + "&redirect_uri=" + Router.redirectURI + "&response_type=code"
return (pathString, nil)
}
}()
let baseURL = NSURL(string: Router.baseURLString)!
let URLRequest = NSURLRequest(url: NSURL(string: result.path ,relativeTo:baseURL as URL)! as URL)
let encoding = Alamofire.ParameterEncoding.encode(baseURL as! ParameterEncoding)
//let encoding = Alamofire.ParameterEncoding.URL
return encoding.encode(URLRequest, parameters: result.parameters).0
}
}
However I get the following error when building this.
Type 'Router' does not conform to protocol 'URLRequestConvertible'
Does anyone know what I'm missing here?

enum Router: URLRequestConvertible {
static let baseURLString = "www.google.com"
case getToken([String: AnyObject])
var method: HTTPMethod {
switch self {
case .getToken:
return .post
default:
break
}
}
var path: String {
switch self {
case .getToken:
return "token"
default:
break
}
}
func asURLRequest() throws -> URLRequest {
let url = Foundation.URL(string: baseURLString)!
var urlRequest = URLRequest(url: url.appendingPathComponent(path))
urlRequest.httpMethod = method.rawValue
urlRequest.setValue("application/json", forHTTPHeaderField: "Content")
urlRequest.setValue("keep-alive", forHTTPHeaderField: "Connection")
switch self {
case .getToken(let parameters):
urlRequest = try URLEncoding.default.encode(urlRequest, with: parameters)
default:
break
}
return urlRequest
}
}
