Hi, friends! I have a Keynote file, in which I create design for macOS applications settings and system settings, that I use and which are installed on my Mac. I like to record my settings so that every time I reinstall the system or an application I can open my file and set it up exactly the way I want. It's like a user manual, only it looks nice with Mac design elements. And I do it in a presentation (Keynote). I also use a Sketch for the design. I want to turn all this into an app for myself, using Swift Playground. Does anyone know how to, for example, add a macOS Dock icon from a Sketch to Swift Playground?

Does anyone know how to extract files from SharedSupport.dmg? There is a comappleMobileAsset_MacSoftwareUpdate file inside, and inside it there are many files, payload.... how to extract all data from payload files, system files, wallpapers, applications. How do you extract them? Earlier, there was InstallEsd, and I extract all files without problems.
