`import Collections` does make no sense errors.

I downloaded package, I can see it in Package Dependencies tab, [swift-collections | https://github.com/apple/swift-collections.git | Up to Next Major Version] — looks OK.

But (quite strange):

import Collections //🛑 No such module 'Collections'

typealias Objects = OrderedSet<anyHashable> // No error

I took Collection word from a list or typed — no difference.

if I remove import Collections there is no OrderedSet anymore (of course)

Can't compile. Cleaned build folder, restarted Xcode...

What could be wrong with it? Any ideas?
