Apple is planning to add a built-in language translation feature and full Apple Pencil support to Safari in iOS and iPadOS 14, according to details found in a leaked version of iOS 14 by 9to5Mac.
Safari's built-in translation feature would allow users to translate web pages without using a third-party app or service. If such a feature comes to iOS 14, we can probably also count on it coming to the next-generation version of macOS as well.
The code suggests the translation option will be available for each website that's visited, but an automatic translation feature will also be able to be turned on, similar to Chrome's automatic translation. Apple also appears to be testing translation options for other apps, such as the App Store, allowing users to do things like read reviews in other languages.
