I'm working on a new application that is basically a "library" type app similar to iPhoto or iTunes, i.e. the user enters data into the app and it handles storage rather than the user storing files himself.

I'm working on a Snow Leopard app and I'm doing some view animations (swapping them) and I've seen some older examples using NSViewAnimation. I'm wondering if these are completely obsoleted by Core Animation? It seems fairly simple for me to use [[myView animator] setFrame:newSwapFrame]; But I'm just wondering if I'm missing somethin...
