download timeout error message

Question

I am trying to access slides in a folder, and seeing this error when I downloading them thru SwiftyDropbox API.&nbsp;&nbsp;I want to write code to retry said downloads, but how to capture this verbose description to make sure I am retrying for a code -1001.&nbsp;My errorcode looks like this?&nbsp;ClientError: Optional(Error Domain=NSURLErrorDomain Code=-1001 "The request timed out." UserInfo={NSErrorFailingURLStringKey=https://api-content.dropbox.com/2/files/download, NSErrorFailingURLKey=https://api-content.dropbox.com/2/files/download, _kCFStreamErrorDomainKey=4, _kCFStreamErrorCodeKey=-2102, NSLocalizedDescription=The request timed out.})&nbsp;The code that prints this look like this ...&nbsp;&nbsp;func doDownloadError(error: Any, errorSource: String) {&nbsp; &nbsp; &nbsp; &nbsp; //rint("doDownloadError")&nbsp; &nbsp; &nbsp; &nbsp; switch error as!

You can cast that error as NSError to access the specific parts of&nbsp;the error information, such as:
&nbsp;
case .clientError(let clientError as NSError):
    print("ClientError code: \(clientError.code)")
    print("ClientError domain: \(clientError.domain)")
