Alamofire loading from cache even when cache policy set to ReloadIgnoringLocalAndRemoteCacheData

I'm using this way in a project and it's working:

let mutableURLRequest = NSMutableURLRequest(URL: SERVICEURL)
mutableURLRequest.HTTPMethod = "POST"

mutableURLRequest.HTTPBody = self.createJson()
mutableURLRequest.setValue("application/json", forHTTPHeaderField: "Content-Type")
mutableURLRequest.cachePolicy = NSURLRequestCachePolicy.ReloadIgnoringCacheData

request(mutableURLRequest).validate().responseJSON{ response in...

Hope it helps.

Thanks to @FábioSalata I solved my problem like this.

 var req = URLRequest(url: URL(string: "<URL>")!)
 req.httpMethod = "GET"
 req.setValue("application/json", forHTTPHeaderField: "Content-Type")
 req.setValue("<Auth KEY>", forHTTPHeaderField:"Authorization" )
 req.cachePolicy = NSURLRequest.CachePolicy.reloadIgnoringCacheData

 Alamofire.request(req).validate().responseJSON { response in ...

ReloadIgnoringLocalAndRemoteCacheData is not implemented.

Update: Starting with iOS 13, NSURLRequest.CachePolicy.reloadRevalidatingCacheData and NSURLRequest.CachePolicy.reloadIgnoringLocalAndRemoteCacheData are implemented. https://developer.apple.com/documentation/ios_ipados_release_notes/ios_13_release_notes
