I. iOS is Apple's mobile operating system used on iPhones, iPads and iPod touch devices. It was originally developed for the iPhone and now supports additional Apple devices. II. The iOS architecture consists of four main layers - the Core OS layer, Core Services layer, Media layer and Cocoa Touch layer. The Core OS layer interacts directly with hardware while the Cocoa Touch layer provides APIs for building iOS apps. III. iOS has undergone several major version updates since its initial release in 2007. Some key updates include the addition of third-party apps in 2008, Siri voice assistant in iOS 5, a complete visual redesign in iOS 7 and performance improvements in iOS 9. iOS
![• The most advanced mobile experience. Now even more so.
• What’s new in iOS 9.
I. iOS 9 brings you refinements at every level — from the apps you see on
your Home screen down to the foundation of the system. Siri is smarter
than ever, proactive suggestions keep you on track, and multitasking
on iPad hits an all-new high with Slide Over, Split View, and Picture in
Picture. All these enhancements enable your devices
II. iOS 9 is the ninth release of the iOS mobile operating system designed
by Apple Inc which is the successor to iOS 8. It was announced at the
company's Worldwide Developers Conference 2015 on June 8, 2015,
and was released on September 16, 2015.
III. iOS 9 focuses less on new features and more on under-the-hood
optimizations, as well as battery improvements.[1] On September 21,
2015, Apple announced that iOS 9 had been installed on more than
50% of active iOS devices, making it the fastest adoption rate for a new
operating system and significantly faster than that of its predecessor.
As of November 2, 2015, iOS 9 has been installed on 66% of
compatible Apple devices.

- 6. The Layers in iOS Architecture Technology Consists of four Abstraction layers• Core OS Layer • Core service Layer • The Media Layer • The Cocoa Touch Layer Uses Darwin foundation and therefore a unix like OS The user interface of iOS is based on the concept of direct manipulation, using multi- touch gestures.

- 29. Conclusion The objective of the seminar was to study and enhance our knowledge about Apple iOS , mobile operating system. We have learnt about the new features of the iOS 5 operating system. So we have learnt about the layers of iOS technology viz. core OS, core services, media and cocoa touch. The fact that all the information regarding iOS cannot be bound in this Presentation, I have tried to cover almost all points that made study of iOS worthy.
