No file found

There are two major mistakes.

• You have to check if the file exists at fileLocation

  let fileExists = NSFileManager().fileExistsAtPath(fileLocation)
  

• The file path Documents/ doesn't exist at all. You have to get the URL to the documents folder in the sandbox with

  let documentsURL = try! FileManager.default.url(for: .documentDirectory, 
                                                   in: .userDomainMask, 
                                       appropriateFor: nil, 
                                               create: false)
  

  (sorry, that's Swift 3 code)

• Not related to the errors, but after printing the error write return to exit the completion block.

Never use the class names NSURL, NSURLResponse, NSError as variable names, use url, response, error instead.
