Absolutely an error there. If you try to search the literal string "move from swift to Objective-c", Google rejects the precision given there are so few results, and searches only for the words independently. The bulk of results in that case are actually about moving from Objective-C to Swift.

If you search "move from Objective-c to Swift", there are actually enough results that it honors the literal string, yielding far fewer results.

Definitely a major methodology error for pairs with a large asymmetry.

Nonetheless I found the post humorous, and I don't think it was held with the conviction some of the top posts seem to think.
