What is the extension of an application on iOS? An extension is a set of components that an app uses to provide additional functionality. These components are bundled with an app’s binary and are delivered via the App Store. When a user downloads an application, he or she is given the option to install one or more extensions to the app. If a user installs several extensions to the same file, the result is that the app’s functionality is duplicated.
Extensions are useful in extending the functionality of an app. These extensions give users easy access to content and data they need, such as social networks. Nativescript has released beta support for share extensions in iOS 5.3, and has helped developers launch share extensions enabled apps into production.
