Compiler error “expected method not found” when using subscript on NSArray

You’ve got to be compiling with the iOS 6 or OS X 10.8 SDKs — otherwise Foundation objects don’t have the necessary methods for the subscripting bit of the literal syntax.* Specifically in this case, the subscripting expects objectAtIndexedSubscript: to be implemented by NSArray, and that’s a new method that was created to interact with this compiler feature. The parts of the new syntax that just have to do with object creation should work fine, though — I don’t believe that requires any new methods.
