# Accessibility for UIKit Make your UIKit apps accessible to everyone who uses iOS and tvOS. ## Discussion Making your app accessible means making it usable by everyone. By designing your app with accessibility in mind, you make it possible for everyone to enjoy your app. For more information, see . UIKit controls and views come with built-in accessibility, providing an accessible user experience by default. Typically, you don’t need to do extra work to enable the standard accessibility features. In some cases, you might want to modify the default values to better represent your app, to provide additional context, or to modify the user’s flow through the app. UIKit makes these customizations straightforward, involving a few lines of code or Interface Builder adjustments as you define your user interface. For more information about customizing accessibility for UIKit elements, see . If your app contains custom user interface elements that don’t inherit from [`UIView`](/documentation/UIKit/UIView) or one of the other UIKit classes with built-in accessibility, make those elements accessible by subclassing [`UIAccessibilityElement`](/documentation/UIKit/UIAccessibilityElement). If you build your app with SwiftUI, see . ## Topics ### Essentials [UIAccessibility](/documentation/UIKit/uiaccessibility-protocol) A set of methods that provides accessibility information about views and controls in an app’s user interface.
