Yes, you’re right. The question in my mind is whether the array struct ever gets copied in this code — it’s not explicitly passed as a parameter, just closed over. I don’t think I’ve read any docs that describe explicitly what the behavior is, maybe because it only becomes significant when you introduce threads? This situation also begs the question of what kind of lower-level data structure one can use in Swift when Array is too high-level. In Obj-C one can drop down to C arrays, for example. Gerriet, would you mind re-asking your initial question on swift-users? I’d love to hear what the Swift gurus say about it. —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
