Apple UI Design Resources for XD
Here’s a super useful free XD resource coming directly from Apple itself.
The included resources are comprehensive and accurately depict the full range of UI Kit controls, views and glyphs available to developers using the iOS SDK. They make it easier to understand how iOS apps are constructed and how to design apps that match the iOS design language.
A must have for any UI/UX designer who’s going to create an iOS app with Adobe XD.
Free to download from the Apple website. There are also versions available for Photoshop and Sketch.
