Learning iOS

iOS is a mobile operating system developed by Apple; it is a derivative of the Mac OS X desktop operating system, with which it shares many (but not all) common frameworks and other components. These include Cocoa Touch, the Mach/Darwin/XNU kernel and code from the Berkeley Software Distribution (BSD). Each iOS application runs in its own secure sandbox to prevent altering other applications, the operating system, or any other data.

The iPhone is a smartphone made by Apple Inc. It and the iPad, along with several other mobile devices from Apple, run on the iOS operating system, which has its own topic, as does the iPad for device-specific questions. Native iOS applications are written in Objective-C or in Swift using the Cocoa Touch frameworks or HTML5 compiled with the help of a package manager such as Adobe PhoneGap; a common IDE is Xcode.
