iOS developers are some of the most in-demand and well-paid specialists. They generate and implement their ideas for Apple mobile devices: iPhone, Apple Watch, iPad, iPod.

The main task of an OS-developer is to create new applications, user-friendly interfaces, updates, and to make sure that these developments bring profit to the client.

In their work, iOS developers use the Swift programming language, which is relatively easy to learn and error-resistant. As a result, the speed of development increases significantly.

After developing the product, developers test it, fix bugs, test it again and, if everything is OK, place the final version in the AppStore. To make it clear what this product is and how to use it, the developers prepare a brief description and instructions for working with the application.

The work with a particular application does not end here – it is necessary to write updates, add new features and make changes in accordance with user feedback. It is necessary to constantly keep their hand on the pulse and, if necessary, solve disputable issues regarding the created product.
