Concentric shapes are a key element in Apple's new design system, as discussed in the session Get to know the new design system. Concentric shapes are used to create layouts where shapes nest comfortably within each other by aligning radii and margins around a shared center. This approach helps maintain optical balance and is particularly useful in creating touch-friendly layouts.

There are three types of shapes used to build concentric layouts:

  1. Fixed Shapes: These have a constant corner radius.
  2. Capsules: These use a radius that's half the height of their container, naturally supporting concentricity.
  3. Concentric Shapes: These calculate their radius by subtracting padding from the parent container.

Capsules are prominently used in the system for elements like sliders, switches, bars, buttons, and the rounded corners of grouped table views. They bring focus and clarity, especially in touch-friendly environments, while in dense desktop environments, they are best used for standout actions.
