Learning C++ to Contribute to the Swift Compiler The Swift compiler is written mostly in C++ , and this won’t change in the near future. You can extend the standard library using Swift, but if you want to contribute a new language feature or some optimization, you’ll need to write C++.

You use where in Swift to filter things, kinda like a conditional . In various places throughout Swift, the “where” clause provides a constraint and a clear indicator of the data or types you want to work with. What’s so special about where – as you’ll soon see – is its flexible syntax.
