The foundation framework contains code for common code that you can find within apps. This is a quote from apple

The Foundation framework provides a base layer of functionality for apps and frameworks, including data storage and persistence, text processing, date and time calculations, sorting and filtering, and networking. The classes, protocols, and data types defined by Foundation are used throughout the macOS, iOS, watchOS, and tvOS SDKs.

If you want to check out all of its functionality, here's a link to the documentation. https://developer.apple.com/documentation/foundation
