It seems to sit naturally in pure Swift syntax, so I wouldn’t be surprised if it shows up as a language feature before long. However, the drawback is that it’s not compatible with Obj-C-style methods. That’s because Obj-C properties have no mechanism for handling the transfer of control implied by Swift throw/try. I’d recommend you try to avoid calling the Swift side “exceptions”. It’s error handling, and although it’s not completely unlike exception handling in other (non-Obj-C) languages, it’s treacherous to confuse the two when dealing with Obj-C. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
