VoiceOver และป้ายกำกับการช่วยการเข้าถึง

VoiceOver is Apple's screen reader. It speaks your interface aloud so people who can't see the screen can still use your app. 🔊

The good news: SwiftUI auto-generates accessibility for standard views. A Text already reads its content, so you start ahead.

An icon-only button has no readable text, so VoiceOver may say nothing useful. That's when you add an explicit accessibility label.

Attach accessibilityLabel to describe what a control does in plain words, not how it looks.

Write the label as the user's goal. Say Save, not "down arrow icon". The label is meaning, never decoration.

An accessibilityHint tells the user what happens after they act. It is read after the label, with a short pause.

For controls that hold data, accessibilityValue announces the current state, like a slider reading "70 percent".

Use accessibilityElement(children:) to merge a card's pieces into one swipe, so VoiceOver reads it as a single unit.

Add accessibilityAddTraits so VoiceOver announces a view's role, like calling a tappable card a button.

Purely decorative images add noise. Use accessibilityHidden(true) to skip them so VoiceOver focuses on what matters.

Turn on VoiceOver in the Accessibility settings and swipe through your app. Hearing it is the fastest way to spot gaps.

You learned to make controls speak: add an accessibilityLabel for icons, hints for outcomes, and group or hide views so VoiceOver flows clearly. ✨
