Instruction 2

When considering the translation overlay, it’s important to take into account several factors beyond just its core functionality. Apple’s accessibility guidelines provide a comprehensive approach to making user interfaces accessible. Below are some key points to consider when you’re using this simple yet powerful feature.

Accessibility

As the translation overlay comes with default styling from device theme, you need to ensure that the overlay is accessible to all users, including those with visual impairments. This includes considering text size, contrast, and compatibility with screen readers. Even though you can’t customize much of the overlay itself, you should provide accessibility customizing the translate Button and the target TextView in following ways:

Button("Translate") {
    // Perform translation
}
.accessibilityLabel("Translate button")
.accessibilityHint("Translates the cafe review")

    // Perform translation and order a coffee from the menu
}

4. Oyxavj Zsegsoq yi Qnpogax Ficmoyr: Umpionso tgwarez cejyiqx owxunep, qidn ej, ygagqliluoc momitmp, we gne ulesn.

Button("Translate") {
    // Perform translation
    UIAccessibility.post(notification: .announcement, 
      argument: "Cafe review translated")
}

Privacy and Security

Privacy is a crucial concern when using the translation overlay, as this API may handle sensitive or personal data during translations. The translation overlay performs local, on-device translation, so privacy is inherently protected. This is because data does not leave the device, making it ideal for applications handling confidential information.

Testing

Testing the translation overlay is essential to ensure that the translation functionality works correctly, offers a smooth user experience and meets the diverse needs of users across various devices and iOS versions. The overlay API introduces real-time text translations. These are the reason to implement proper testing for the apps using the Translation APIs:
