Apple's system fonts, particularly the SF family of typefaces, are a key component of their design system. These fonts are variable fonts, which means they allow for a range of stylistic options by adjusting qualities like weight, width, and corner softness on a continuous scale. This flexibility is particularly useful in creating dynamic and accessible user interfaces.

For instance, in the session Say hello to the next generation of CarPlay design system, it is highlighted that the SF family of typefaces is used because they are variable fonts, allowing for a wide range of stylistic options beyond the traditional light, regular, or bold options.

Additionally, the session Get started with Dynamic Type discusses how the system font is a great starting point for implementing dynamic type in your apps. Dynamic type allows text to adjust automatically to different sizes, improving readability and accessibility. This session also covers how to use built-in text styles with SwiftUI and UIKit to ensure that text scales appropriately with user preferences.

For more detailed information on how to implement and test dynamic type in your apps, you can refer to the chapter markers in the session "Get started with Dynamic Type":

These resources will help you understand how to effectively use system fonts and dynamic type to create accessible and visually appealing apps.
