Swift: how can I create external interface for static library (public headers analog in Objective-C .h)

Question

I need to create a static library with Swift, and I need to know how can I implement interface for the library.

In Objective-C I can mark needed headers as public in

If you want your Swift framework to expose certain classes to the interface, simply mark the 'entities' (functions, variables etc.) public:

public class Class {}
public var variable: Int
public func function() { }

By default, all entities have internal access.

• public entities are intended for use as API, and can be accessed by any file that imports the module, e.g. as a framework used in several of your projects.
• internal entities are available to the entire module that includes the definition (e.g. an app or framework target).
• private entities are available only from within the source file where they are defined.
