# SecurityUI

The SecurityUI framework provides a public API for displaying certificates, including support for Qualified Web Authentication Certificates (QWAC).

## Overview

For apps that use UIKit or AppKit, create an instance of [`SFCertificatePresentation`](/documentation/SecurityUI/SFCertificatePresentation), set its [`trust`](/documentation/SecurityUI/SFCertificatePresentation/trust) object, and customize its display properties. Then, use the presentation object to present a sheet in a <doc://com.apple.documentation/documentation/UIKit/UIViewController> (UIKit) or <doc://com.apple.documentation/documentation/AppKit/NSWindow> (AppKit). In SwiftUI, use the <doc://com.apple.documentation/documentation/SwiftUI/View/certificateSheet(trust:title:message:help:)> view modifier to present a sheet for a given trust object.

## Topics

### Essentials

[`SFCertificatePresentation`](/documentation/SecurityUI/SFCertificatePresentation)
