You can just do what you have mentioned:

import Foundation
...
string.contains("Swift");

From the docs:

Swift’s String type is bridged seamlessly to Foundation’s NSString class. If you are working with the Foundation framework in Cocoa or Cocoa Touch, the entire NSString API is available to call on any String value you create, in addition to the String features described in this chapter. You can also use a String value with any API that requires an NSString instance.

You need to import Foundation to bridge the NSString methods and make them available to Swift's String class.
