Interesting. I would definitely look into this if I ever need to do another iOS app.
How does it work in a language without garbage collection? If you replace an element in a vector and only keep a reference to the new vector there will be a stray element there that would need mopping up. Is ARC clever enough to recognise this? I wouldn't have thought so unless you maintain a reference count for every element within the vector.. Which I don't imagine would be particularly efficient.
