iPhone operating system iOS supports Objective-C, C, C ++, programming language Swift. It is based on Macintosh OS X. iPhone, iPod touch and iPad all come with IOS. Thus, targeting smart wearables like the apple watch. Hence iOS platform is trending
What is iOS? Let’s have the iOS platform overview. iOS is Apple’s proprietary operating system that runs on the iPhone, iPod Touch, and iPad.
Cocoa Touch frame and various user interface components are specific to iOS. Here are key features of the iOS platform include :
- Conventions designed the user interface and consistent
- Design that is minimal
- Guidelines related to apple human interface
- Cocoa Touch
- Cured and application distribution system closely controlled
Making an app for iPhones and iPads is easier and faster than making an app for Android phones. iPhones use a simple language called Swift, while Androids use a more complicated language called Java.
Android phones have many different types, which makes it harder to make apps that work well on all of them. But iPhones are all the same, which makes it easier to make apps for them.
However, Apple has very high standards for apps that go on the App Store, and it can take a long time for them to approve an app. So even if you make an app for iPhones, it might not be allowed on the App Store if it’s not good enough.
- iOS powers the iPod Touch, iPhone, and iPad
- As a matter of fact, 1 billion iOS devices sold as per the announcement at the start of 2015
- Also, Currently over 1.4 million apps on App store
- Identically, iOS is the operating system that powers the iPod Touch, iPhone, and iPad. Additionally, it powers the Apple TV
There are currently over 1 billion iOS devices that have been sold. Thus it is rather an incredible number especially considering the platforms have only been available for a few years.
It’s the new market of India and China that will take this market to an even greater number in the many more years to come.
As of now, there are over 1.4 million apps available on the App store. This has been a very popular platform for developers.
iOS architecture is a layered architecture. At the top level, iOS acts as an intermediary between the underlying hardware and applications are made. However, applications do not communicate directly with the underlying hardware. Similarly, applications talk to the hardware through a collection of well-defined interface systems.
These interfaces make it easy to write applications that work consistently on devices that have different hardware capabilities.
Lower layers provide basic services to all applications. Likewise, it is based on the upper layer level and gives a sophisticated graphics interface and related services.
Apple provides most of its system interfaces in special packages called frames. A frame is a directory that contains a dynamic shared library that is filed, such as header files related images and helper applications needed to support that library resources. Thus, each layer has a set of the framework that the developer uses to build applications. Here is the layered architecture of the iOS platform.
Cocoa Touch is a user interface framework. It is used for building software programs to run on iOS.
It provides an abstraction layer iOS, the operating system for the iPhone, iPod Touch, and iPad. Similarly, Cocoa Touch is based on macOS set of API tools and cocoa, as it is written mainly in Objective-C language. Thus, Cocoa Touch allows the use of hardware and features not found in Mac OS computers and therefore are exclusive to the range of iOS devices. Furthermore, Cocoa Touch follows the architecture of the Model-View-Controller (MVC) software.
Cocoa Touch contains a different set of control elements graphics from cocoa. Thus, tools to develop applications based on Cocoa Touch applications are included in the iOS SDK of iOS platform.

Core services layer. Some of the major frameworks available in the layers of basic services are as follows:
- Marco Address Book – Allows programmatic access to a database of user contacts. Thus, maintaining records.
- Cloud Frame Kit – Provides a means to move data between your application and icloud.
- The framework of basic data – Technology management data model of an application of Model View Controller.
- Core Foundation framework – The interfaces that provide management functions critical data and application services for iOS. Thus, providing core foundation facilities.
- The Core Location framework – The location and heading information applications.
- Core frame motion – access all data based on movies available on a device. Using this information framework based core of the accelerometer can be accessed movement.

The core layer OS is the last layer of the stack and IOS is directly on top of the hardware device. Likewise, this layer provides a variety of services including networking low-level access to external accessories and usual services such as memory management, file system management, and basic operating system threads.
The core layer of the operating system has characteristics of the low level that most other technologies are based on :
- Bluetooth Framework core
- Accelerate framework
- Marco external accessory
- The framework security services
- Local authentication framework
- 64-bit support iOS7 supports the development of 64-bit applications and allows the application to run faster
Core OS layer provides the following services :
- Security Services
- Networking
- Threading
- Standard
So, to keep it short, it is a very SIMPLE level of functioning at the top layers (Cocoa Touch) and as we move down to Core OS, the amount of code that we write and the complexity of the code generally increases.
