I really don’t agree with this post: No Single Swift Style by Jeremy Sherman.
His conclusion (that we won’t end up with one idiomatic style) may be correct, but I really don’t think it would be a good thing.
In fact I think it would be a pretty damning indictment of the language if it was seen to be "too big to be confined to having a single style”.
It would certainly be grist to the mill for people who argue that Swift is too much of a bastard child formed from many disparate influences. I’m not totally sure I buy into that as a criticism - I don’t think a synthesis of old stuff to form something new is necessarily a bad thing at all - but I certainly do think that not all choice is good. Just because we can do things in ten different ways in a given language, it doesn’t mean we should. I rather hope that we do develop some best practise, and that it falls naturally out of the best features of the language (whatever they turn out to be).
