Such a weird ranking. Looking up how Tiobe perform it's ranking, it seems like they base it on search engine hit counts for the query '+"<language> programming"'. I would not rely on this

If you’re going to program a Mac or an iOS device, you’re going to use Swift or ObjC. The former is at 0.87%, the latter at 0.45%

Those figures seem rather low for one of the larger platforms on the planet.

As a reminder, this is an index that ranks Perl, Object Pascal and Fortran above Go and PHP. It means absolutely nothing.
