According to NSURLSessionDownloadTask issues with Storage almost full disk warnings and https://forums.developer.apple.com/thread/43263 it would seem that you will get an error and its domain will be NSPOSIXErrorDomain with an error code of ENOSPC (Error, No Space).

There is also the possibility of getting an error with the domain of NSCocoaErrorDomain and an error code of NSFileWriteOutOfSpaceError.

public func urlSession(_ session: URLSession, task: URLSessionTask,  didCompleteWithError error: Error?) {
    if let nserror = error as? NSError {
        if (nserror.domain == NSPOSIXErrorDomain && nserror.code == ENOSPC) ||
           (nserror.domain == NSCocoaErrorDomain && nserror.code == NSFileWriteOutOfSpaceError) {
            // Not enough space
        }
    }
}
