And if you’ve opened this post in the Developer application, you will also listen to about navigational factors in the app.

No matter if you individually use VoiceOver or not, here’s how you can place yourself in the frame of mind of individuals who do to aid design and style a standout encounter.

Grasp accessibility features in your app

When somebody permits VoiceOver on iOS, iPadOS, watchOS, or tvOS, it begins describing all of the labeled features on screen. To decide what to go through, VoiceOver seems for accessibility things — unique or grouped visible things in just a perspective — as nicely as whether a person can interact with these aspects. As it describes an factor, VoiceOver also highlights it on display screen by exhibiting a black rectangle close to the content.


Tip: Discover VoiceOver on your individual unit

While Xcode presents you with several equipment to exam your app’s accessibility, you can study a lot about VoiceOver and how different applications have executed it by taking a test travel on your possess Apple iphone, iPad, Mac, Apple Observe, or Apple Television set. You can enable VoiceOver in the Configurations application or Process Tastes on your Mac, and if you want to have effortless access to the element, you can even help a hardware-dependent Accessibility Shortcut.


VoiceOver also provides a couple particular multitouch gestures and faucets to assist people navigate their device. Swiping to the appropriate wherever on the monitor will navigate to the next element in the look at, while swiping to the remaining will navigate to the former one particular. Every single time VoiceOver lands on a new ingredient, it speaks particulars like its accessibility label and benefit aloud, alongside with hints or traits if the ingredient has any.

Alternatively, persons may well tap directly on a visual ingredient to navigate to it. If it is within just the bounds of an accessibility component, VoiceOver will emphasis on it. Usually, VoiceOver will emit a “boink” audio.

Group and declutter accessibility components

When navigating by swiping, VoiceOver visits every single element in order of its visual appeal on the monitor. That said, this is not constantly the most productive way for another person to take in information: If your application has also lots of accessibility components, it could acquire someone a really very long time to realize it. Instead, look for options to group your accessibility factors jointly and produce a simplified hierarchy.

When you team your accessibility elements, VoiceOver will describe them together, which can velocity up navigation as a result of your application. For instance, you may possibly team a watch that consists of a title, text, and a time stamp label, as with Health’s Heart Charge title, heartbeat reading through, and time of most up-to-date looking through.

The Health app uses grouped elements in the Summary view to provide a streamlined experience for people using VoiceOver.

Personalized steps let individuals who use VoiceOver have obtain to all those exact same features in a distinctive manner: When VoiceOver focuses on the concept element, it speaks the hint “Actions Readily available: Swipe up or down to find a custom made motion.” When you get there at the motion you want, you can double-tap to carry out it.

Tailor made steps are really potent when blended with grouped things and can assistance simplify your navigable hierarchy. If you have a perspective as an accessibility ingredient that has many buttons as subviews, for illustration, you aren’t usually ready to navigate to all those buttons with VoiceOver. Although it may be tempting to break up this up into smaller sized factors and let buttons to develop into independently focusable, this may possibly increase litter.

We strongly advise using Custom made Actions to expose these button actions, allowing you continue to keep the element’s firm though nevertheless giving total controls to another person utilizing VoiceOver. When you very carefully group your things and insert custom made steps, it results in a greater in general navigation practical experience and will make your application far much more enjoyable for persons who count on VoiceOver.
