Safari extensions
Enhance and customize the web browsing experience on iPhone, iPad, and Mac with
Safari extensions.
Using powerful native APIs and frameworks, as well as familiar web technologies such as HTML, CSS, and JavaScript, you can easily create
Safari extensions
in Xcode and distribute them on the
App Store
in the Extensions category. Xcode 12 and later supports the popular WebExtension API and includes a porting tool to make it easy to bring your extensions to Safari.
