Simply put, iOS development is the process of creating applications for Apple's mobile operating system, the operating system used by the iPhone and iPod Touch. In this most important sense, it has a lot in common with other types of software or application development, but there are some key differences. One of the things that makes mobile app development different from many other apps is that because apps are designed to run on mobile devices with more power, they rely on a network connection. to take advantage of computer software. To give an example: there are translation programs that you can load on a desktop computer and run locally, including their large databases. In contrast, in the conversion process written for iOS or another mobile platform, the installable software package - the application that lives on our phone - is basically to create a touch point that the user can s' interface; the application sends a request to a remote platform that does the actual translation, and the results are sent back to the application for the user to read.


This type of client server allows the application to take up less memory on the device and provides a simpler configuration and user experience, but adds complexity on top of the software running locally. From now on, this application must communicate with the network of remote actors. Not all iOS apps require a mobile connection to work (you can use a sketchbook app without first connecting to a network, for example), but all mobile apps require a connection to be installed and updated, an issue for the iOS developer. consider. attention.


Today, the smartphone operating system market is dominated by two major players: Google's Android and Apple's iOS. While Android is open-source, iOS is only used on Apple hardware. This leads to another big difference between iOS development and the development of other types of software: iOS developers rely on two programming languages, Swift and Objective-C, which are often used externally of the Apple ecosystem. . Although Objective-C dates back to the early 80s and is part of the same family of languages as C and C++, Apple developed Swift for iOS and is a new feature, first released in 2014.

What are the responsibilities of an iOS Developer position?

An iOS developer job description may include all of the following duties: 


  1. Design and develop advanced applications for mobile devices that use Apple's iOS platform 
  2. Work with cross-functional teams to design, define and deliver new application functionality. Team tests code for robustness, including usability, usability, and general reliability to ensure software quality and performance.
  3. Identify potential problems, fix bugs and fix app crashes. Bug fixes before final release.
  4. Publish apps in the app store. Manage iOS app code with atomization and design and implement app updates.
  5. Continually identify, evaluate and implement new technologies to increase the efficiency of application development.
