Improving Accessibility with SwiftUI ViewModifiers

Accessibility is a crucial aspect of app development, ensuring inclusivity for all users. SwiftUI provides powerful modifiers that enable developers to create apps that are accessible to everyone. In this blog post, we’ll explore how SwiftUI’s Accessibility modifiers can be utilized to improve the usability and experience of your app for people with various needs.

What are Accessibility Modifiers?

Accessibility modifiers in SwiftUI are tools that allow developers to enhance the accessibility of their app’s user interface elements. These modifiers help in making the app more usable for people with disabilities, such as visual impairments or motor skill limitations. They provide features that assist users in navigating and interacting with the app more comfortably. Feel free to check the Apple documentation.

Examples of Accessibility Modifiers:

accessibilityLabel:

The accessibilityLabel modifier allows you to provide a descriptive label for an element, making it accessible to VoiceOver users. For instance:

Text("Submit")
    .accessibilityLabel("Button for submitting the form")

accessibilityHint:

Use the accessibilityHint modifier to provide additional contextual information about an element's functionality. This helps VoiceOver users understand the purpose of an element or based on Apple doc:

Communicate to the user what happens after performing the view’s action.

Button(action: submitAction) {
    Text("Submit")
}
.accessibilityHint("Tap to submit the form")

accessibilityValue:

For elements with changing values, such as sliders or progress bars, the accessibilityValue modifier can convey the current value to assistive technologies or based on Apple doc:

Adds a textual description of the value that the view contains.

Slider(value: $sliderValue, in: 0...100)
    .accessibilityValue("\(Int(sliderValue))")

accessibilitySortPriority:

The accessibilitySortPriority modifier allows you to set the order in which elements are read by VoiceOver. This is useful when elements are visually ordered differently from their logical reading order or based on Apple doc:

Sets the sort priority order for this view’s accessibility element, relative to other elements at the same level.

VStack {
    Text("Title")
        .accessibilitySortPriority(1)
    Text("Subtitle")
        .accessibilitySortPriority(2)
}

Conclusion:

Accessibility is a fundamental aspect of creating inclusive apps. SwiftUI’s Accessibility modifiers empower developers to ensure their apps are usable by everyone. By utilizing these modifiers, you can enhance the user experience for individuals with disabilities, contributing to a more inclusive digital environment.

By embracing Accessibility modifiers in your SwiftUI projects, you’re not only building better apps but also making a positive impact on the lives of users who rely on these features to navigate and interact with technology.
