You've got you access of the JSON dictionary around the wrong way. The top level objects are dictionaries, but you are treating them as arrays and trying to load by the indexPath.row.
Something like this should work instead:
cell.textLabel.text = _objects[@"Name"][indexPath.row];
cell.detailTextLabel.text = _objects[@"URLs"][indexPath.row];
Broken out, it looks like this:
NSArray *nameArray = _objects[@"Name"];
NSArray *urlArray = _objects[@"URLs"];
cell.textLabel.text = nameArray[indexPath.row];
cell.detailTextLabel.text = urlArray[indexPath.row];
