As someone who hasn’t dipped his toe into Swift yet, this sort of thing is a major disincentive. The explanation as to why Swift doesn’t suck doesn’t fit any notion in compuer science that I have ever heard of in almost 40 years of programming. Maybe it’s just the jargon that needs a clearer explantion (I suspect it is), but when things are as clear as mud as this, you are not going to see the adoption rates you want. —Graham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
