I would not recommend using this as the name for your NSView subclass,
since ObjC lacks namespaces. I doubt there's still a View class
hanging around anywhere, but it's safer to prefix it with some
initialism of your own.

First of all, as the documentation you quoted explains, -validate is
an NSToolbarItem method, not an NSView method. If you want custom
validation logic for your view-based NSToolbarItem, you must subclass
NSToolbarItem and override -validate.
But since you're not actually doing any validation logic, there's no
need to implement custom validation at all, at least until you provide
an overflow menu representation for your toolbar item (which as the
documentation describes is disabled by default).

Looks like you changed your NSToolbarItem into a View by mistake.
