How to display a list of all standard libraries?

Question

Apple Xcode

Hello! I work in Xcode, I'm taking a course (iOS Development Course Beginner). It is already several years old and Xcode has been updated several times. In the video, the author has a navigator for "apple" headers in the left panel under the project files, but in the latest version I don't see this and I can't find it anywhere in the settings. Tell me - is it possible to display such a panel now? I would like to have it at hand for self-analysis.
