Every operating system or project in the world has a Kodi name, which developers and project owners use to express it and leave the administration to search for a suitable trade name, for example the word "Manhattan Project" was used to refer to the project that developed the first atomic bomb in history, "Longhorn" was the code name for Windows Vista, and the iOS operating systems we see only in numbers, such as iOS 5 or iOS 3, and so on. Have you thought what the code names for these systems were before their release?

Apple did not use an organized series of names in the code naming of its systems, so sometimes you find names from nature, sometimes animals, and so on, and this is a list of the names of the systems that mean:
iOS 1.0: Alpine.
iOS 1.0.2: Heavenly.
iOS 1.1: Little Bear.
iOS 1.1.1: Oktoberfest.
iOS 1.1.2: Snow Bird.
iOS 2.0: Big Bear.
iOS 2.1: Sugarbowl.

iOS 2.2: Timberline.
iOS 3.0: Kirkwood Forest.
iOS 3.1: Northstar.
iOS 3.2: “Wildcat” (iPad only).
iOS 4.0: Apex Summit.
iOS 4.1: Baker.
iOS 4.2: Jasper.
(iOS 4.2.5 - iOS 4.2.10): Phoenix.
iOS 4.3: Durango.
iOS 5.0: Telluride.
iOS 5.1: Hoodoo.

Finally the current system, iOS 6.0, is called “Sundance”.
