The Facebook Design team has updated its collection of articles, videos, and resources.
These include a comprehensive iOS 10 UI Kit (remember, this team now includes Tehan+Lax folks, the #OG iOS Kit makers). The new iOS 10 kit is available in Sketch, Photoshop and Figma formats. #wow
The Devices imagery section is also updated with latest hardware in Sketch format. This really cements the Facebook Design website as an indispensable resource for app designers.
