I'm beginning to delve into Core Data and I've been looking at the
generated code for the Xcode Core Data project. I'm finding their
implementation of -applicationSupportFolder interesting. They grab the
NSApplicationSupportDirectory using
NSSearchPathForDirectoriesInDomains, which makes sense, but then they
go on to do a check to make sure the directory was retrieved looking
at the item count in the returned NSArray. If count is not greater
than 0 then it returns an NSTemporaryDirectory. What's the point? Is
that check really necessary? Will there ever be an instance where
NSSearchPathForDirectoriesInDomains will not return the
NSApplicationSupportDirectory when asked for? If so, why and what
would be the appropriate way to handle this?
