Alamofire.download() method: Where is the file and did it save successfully?

Question

The example for using Alamofire.download() works just fine, but there isn\'t any detail in how to access the resulting downloaded file. I can figure out where the file is and wh

Answer 1

The example on the Alamofire readme file actually has the file path in it, so I grab it with a separate variable to use elsewhere in my code. It is not very elegant and I am hoping there is a way to get that info in the response, but for now, this is getting the job done:

var fileName: String?
var finalPath: NSURL?

Alamofire.download(.GET, urlToCall, { (temporaryURL, response) in

    if let directoryURL = NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)[0] as? NSURL {    

        fileName = response.suggestedFilename!
        finalPath = directoryURL.URLByAppendingPathComponent(fileName!)
        return finalPath!
    }

    return temporaryURL
})
    .response { (request, response, data, error) in

        if error != nil {
            println("REQUEST: \(request)")
            println("RESPONSE: \(response)")
        } 

        if finalPath != nil {
            doSomethingWithTheFile(finalPath!, fileName: fileName!)
        }
 }
