They're still only available if you import Foundation. They're just NSString methods with wrappers. The real problem is just that Swift itself doesn't have methods for locating a string in another string, or replacing strings in another string.
This is why I was careful to say that Swift's API is the best in terms of its fundamental design. It still has a lot of missing functionality compared to other languages right now.
