I have a lot of respect for Lattner, obviously, but Swift has spent a LOT of goodwill that people were willing to spare it. Unless IBM pulls a really good thing out of their hat, I fear that swift might be in a perl6 position where they finally made a language worth a shit, but ran out of gas as they reached top speed.
I guess time will tell. I WANT swift to be awesome, but in order to make it a rational choice, I NEED swift to be stable, common, and approachable for new employees. (something scala can struggle with for some programmers)
It's really gonna bum me out when swift4 gets announced this spring (/s) and completely ruins everything, and then swift5 would of course be announced around the time swift4 becomes even remotely stable.
It's just been a disaster so far.
