Alamofire Type 'ParameterEncoding' has no member 'URL' Swift 3

Question

I am trying to migrate my codes from swift 2 version to swift 3 version. I could not migrate following code part and I did not find any solution for it. How can I do it?

I'd change the name of this computed property to, say, request, to avoid clashing with the new type name, URLRequest. Coincidentally, this computed property should use a type of URLRequest:

public var request: URLRequest {
    let url = URL(string: Router.baseURL)!
        .appendingPathComponent(Router.basePath)
        .appendingPathComponent(path)

    var request = URLRequest(url: url)
    request.httpMethod = method.rawValue

    var parameters = [String: Any]()
    parameters["key"] = Router.key
    parameters["hl"] = "en"

    switch self {
    case .getMostPopularVideos(let pageToken):
        parameters["part"] = "snippet,contentDetails,statistics"
        parameters["chart"] = "mostPopular"
        parameters["videoCategoryId"] = TubeTrends.Settings.topTrendsCat
        if let pageToken = pageToken {
            parameters["pageToken"] = pageToken
        }
        return try! Alamofire.URLEncoding.default.encode(request, with: parameters)
    }
}
