Swift Question

Type does not conform to protocol 'URLRequestConvertible' with Alamofire

Here's the code:

enum Router: URLRequestConvertible {
//Error: Type 'Five100px.Router' does not conform to protocol 'URLRequestConvertible'

static let baseURLString = "https://api.500px.com/v1"
static let consumerKey = "MY_KEY"

case PopularPhotos(Int)
case PhotoInfo(Int, ImageSize)
case Comments(Int, Int)

var URLRequest: NSURLRequest {

let (path, parameters) : (String, [String: AnyObject]) = {

switch self {

case .PopularPhotos(let page):
let params = ["consumer_key": Router.consumerKey, "page": "\(page)", "feature": "popular", "rpp": "50", "include_store": "store_download", "include_status": "votes"]
return ("/phtos", params)

case .PhotoInfo(let photoID, let ImageSize):
var params = ["consumer_key": Router.consumerKey, "image_size": "\(ImageSize.rawValue)"]
return ("/photos/\(photoID)", params)

case .Comments(let photoID, let commentsPage):
var params = ["consumer_key": Router.consumerKey, "comments": "1", "comments_page": "\(commentsPage)"]
return ("/photos/\(photoID)/comments", params)
}
}()

let URL = NSURL(string: Router.baseURLString)
let URLRequest = NSURLRequest(URL: URL!.URLByAppendingPathComponent(path))
let encoding = Alamofire.ParameterEncoding.URL

return encoding.encode(URLRequest, parameters: parameters).0
}
}


I imported Alamofire and added this code, then comes the error. I wrote this code according to raywenderlich tutorial: http://www.raywenderlich.com/85080/beginning-alamofire-tutorial, which is written in Swift 1.2 while I use Swift 2.

Answer

You need to return an NSMutableURLRequest in the URLRequest property instead of an NSURLRequest. That will fix up the error.
