iOS

iOS is a mobile operating system for Apple-manufactured devices. iOS runs on the iPhone, iPad, iPod Touch and Apple TV. iOS is best known for serving as the underlying software that allows iPhone users to interact with their phones using gestures such as swiping, tapping and pinching. Developers can use the iOS software development kit (SDK) to create applications for Apple mobile devices. The SDK includes tools and interfaces for developing, installing, running and testing apps.
