Who is and what does a Mobile App Developer do?

Mobile Developer, is a person who creates functional and aesthetically pleasing applications that meet all the needs of the end customer. Such a developer specializes in mobile technologies such as app development for the aforementioned Android, iOS, or Windows Phone systems. Mobile app developers create, test, update and manage mobile apps throughout the app lifecycle. They are responsible for both programming the mobile application and designing its user interface.

The main task of a Mobile Developer is designing and coding mobile applications and taking care of their development and updating (also in client-server architecture), dealing with issues of relational databases. Mobile Developers must also take care of the code quality, as well as write unit and functional tests, because nowadays both clients and end users are very demanding and expect a product of the highest quality, working flawlessly.

The Mobile Developer works closely with the entire development team and with the client itself. He may receive assistance from the project team in creating mock-ups of the application and cooperate with other teams in the organization in order to coordinate the deployment strategy.

What skills should a Mobile App Developer have?

A mobile app developer needs to know the right languages and technologies to practice their profession. There are two main positions: iOS Developer and Android Developer. The differences are closely related to the software itself, and in a nutshell, Android is a universal and open system, while iOS on the contrary – a significant part of the software is created internally by Apple. Each application coming from “outside” is carefully analyzed and subjected to numerous tests.

What does an iOS Developer do?

An iOS Developer creates, tests, and updates apps for iOS devices. For this platform, until recently, proficiency in Objective-C was sufficient. Nowadays, Xcode (a development environment) is mainly used to create iOS apps and Swift, which replaced Objective-C and became the primary iOS programming language, was implemented in the eighth release of the system. However, knowledge of Objective-C can be useful when you have been writing iOS applications for 2-3 years and want to get to know this platform better. It is worth knowing its basics, as well as the elements that influenced the Swift language, i.e. the Objective-C Runtime and the object-oriented approach it implements. Knowledge of Objective-C is also useful for understanding how external libraries work that have not yet been fully ported to Swift, or for working on programs written in Objective-C. An iOS developer should be able to design and architect iOS device applications from scratch.

Skills an iOS Developer should have

  • Swift

Swift is the main programming language used to develop iOS apps. It is a very modern programming language, relatively easy to learn, and frequently updated. A successful iOS developer should have a good understanding of Swift and its core concepts.

What does an Android Developer do?

Android is the most popular mobile operating system in the world, and the devices supported by it are expected to grow in the future.

For programming on the Android platform, it is necessary to know primarily Java. It is not uncommon for a mobile application developer to use frameworks such as Core Data, Networking, and Push Notifications in his work. According to one of the Android Developers from KISS Digital, it is advisable for a mobile application developer to be familiar with reactive programming, with a particular focus on the ReactiveX library, and to have a good command of English.

Skills an Android Developer should have

  • Building user interfaces

That is, the ability to turn a design into a functional Android application using Java and XML. To do this, an Android Developer must know how to use all the conventional view containers and know all the standard views, as well as other components that may appear in an Android application.

  • Data storage and notifications

An Android Developer should know how to store, update and delete information on an Android device. Even if he relies on external APIs for the application, he still needs to store the information locally, on the user’s device. Also, he should be able to implement push notifications to reach more users.

  • Material Design Guidelines

Many Android apps use the Material Design framework, created by Google in 2014. For this reason, an Android Developer should know how Material Design works in the context of designing and developing new apps. Additionally, the ability to implement basic Material Design guidelines in an app is essential.
