A software application designed for use on iPhone devices powered by Apple’s iOS. Accessible via the Apple App Store, iPhone applications are designed to run on the iOS mobile operating system of Apple, which drives the iPhone and the iPad and iPod Touch devices of Apple.
iOS operating system
iOS is an Apple-developed mobile operating system. It was initially called the iPhone OS, but in June 2009, it was renamed iOS. Currently, iOS runs on iPhone, iPod touch, or iPad. Like other modern operating systems, iOS uses a graphical user interface or GUI. However, because it’s a mobile operating system, rather than a keyboard and mouse, iOS is built around touchscreen input. For example, it is possible to open applications or “apps” with a single tap rather than a double-click. By swiping your finger over the screen, different screens can be displayed rather than clicking on open windows. iOS is a closed system, which means that no third-party apps were allowed to run on the device in the iPhone OS.
iOS App Store
The Apple App Store is a digital distribution platform where digital software and applications can be bought and downloaded by people. Apps is an abridgment of the word “applications.” Apps are software tools that provide additional functionality to an operating system. Apps purchased from the Apple App Store are stored in the iCloud – cloud storage and cloud computing service from Apple for easy access from any signed-in device.
iOS software development kit
To create applications for Apple mobile devices, developers can use the iOS software development kit (SDK). The SDK includes tools and interfaces for developing, installing, running, and testing apps. Native apps can be written using the iOS system frameworks and the Objective-C programming language. Xcode Tools are included in the iOS SDK and include an Integrated Development Environment (IDE) to manage application projects, a graphical user interfaces creation tool, and a debugging tool to analyze runtime performance. It also includes an iOS simulator that allows developers to test apps on a Mac and a library of developers for iOS that provides all the documentation and reference material required.
