Facebook iOS 10 Light contains the stuff you use the most when designing for iOS. Most of the components there match vanilla iOS components so you can be confident designs map to the tools your engineers use. In Figma, Sketch, and XD, we’ve worked in 1x and in Photoshop at 2x. Where possible we’ve tried to make components scale across device widths.
In addition to the commonly used UI elements, Facebook iOS 10 contains a ton of elements found throughout the latest iOS release.
