You can still override -dealloc in ARC. You just can't release anything (ARC will do that for you; you can assign to nil if you need explicitly clear the pointer), nor can you call [super dealloc] (again, ARC will do that for you at the end of your -dealloc implementation).
But you should not be holding on to resources like file handles until -dealloc. You have no idea who might have retained a pointer to your object—use an explicit -close method instead.
