// App Sandbox:
// Project / Target / Signing & Capabilities / App Sandbox / File Access / Downloads Folder:
// "com.apple.security.files.downloads.read-write" OR "*.read-only"
- (NSURL*)downloadsURL:(NSError**)error{
    NSFileManager *fm = [NSFileManager defaultManager];
    NSURL *sandboxDownloadsURL = [fm URLForDirectory:NSDownloadsDirectory
                                            inDomain:NSUserDomainMask
                                   appropriateForURL:nil
                                              create:YES
                                               error:error];
    NSURL *resolvedURL = sandboxDownloadsURL.URLByResolvingSymlinksInPath;
