Have hidden implementation of functions in Swift like in the documentation?

Question

I am building a rather large library and I think it would be a lot cleaner if I could have the implementation for my methods and such hidden. For example, when you view the in-code documentation for standard Swift types, such as UInt64, you see things like:

With the actual implementation of the methods hidden, and only the declarations and headers shown. How can I do this with my own library?

Answer 1

You need to distribute your library as a precompiled binary, in which case only the public headers + documentation will be visible for consumers of your library.

For more information, you can watch the WWDC2019 video of about Binary frameworks in Swift.
