Oh God, they just compared the speed of Objective C, Swift and... Python! It's nice to see Swift being faster than Objective C, etc., but what has Python got to do with coding native iOS/OS X apps? Of course it's going to fail at speed when compared to a static compiled language. What a weird and pointless comparison, imo (I mean the inclusion of Python, seems so random to me).
It's neither weird nor pointless. They're going for something that is as comfortable to work with as modern dynamic languages, for something that eschews the cruft of ObjC. Python is simply a very popular representative for this type of language. Of course, it's an easy target. But I can see why they went for it.
Yeah, I kind of get it after some additional thought (and reading through the replies).
Maybe I missed out on some detail (not watching the live video, just a text stream) – now that I've taken a look at the syntax, the comparison seems more valid. Still, comparing this to Javascript would've been more interesting (webapps, all that stuff).
