The mobile application industry is huge and growing, according to some research, the total value of the mobile app industry will increase to $ 407 billion by 2026. With this growth, the market looks very profitable and offers many possibilities.

The figure that deals with the development of mobile applications are called: Mobile App Developer, these figures are responsible for the development and maintenance of the applications we use on our phones, both on Android and iOS.

With the right mobile app development skills, you can go several ways, work as a freelance developer or decide to pursue a professional career, which can offer attractive salaries and lucrative job prospects. But knowing how to become a mobile app developer may not be that clear. That is why we have decided to create a how-to guide for you to become an app developer.

  1. iOS Developer

IOS developers create, test, and update applications for iOS-based devices. They normally use Xcode as their development environment and Swift as their main iOS programming language.

2. Android developer

Android developers are responsible for developing applications for Android devices. They design and develop applications, then test the code for edge cases and general usability.

Also, in this case, the programming languages differ in the operating system for which we are going to develop the application:

Initially, as the first language to develop apps for iOS, one of the few choices was Objective-C, an object-oriented superset of the C programming language that has been the focus of iOS development so far. In 2014, Apple launched Swift, a new programming language for iOS mobile apps that offers iOS developers an alternative

Swift is designed to be compatible with all existing iOS development tools — Xcode, Objective-C, and more — but due to its ease of use and improved functionality, it is rapidly starting to replace Objective-C.

While, as far as Android is concerned, compared to iOS, we have many more languages to choose from, among them, there is certainly Java, which for many years has been a great choice for all Android developers, but over time this language has become increasingly obsolete and is being replaced by Koltin, so much so that Google is also trying to make Kotlin it's the standard language for Android development

Kotlin was developed by JetBrains in 2011, and in 2017 Google began supporting Kotlin as an alternative language for Android app development.

If you’re familiar with Android Studio, you should know it’s a joint project from Google and JetBrains, so here the dots link again. In terms of complexity, Kotlin is fairly simple compared to Java.

Another great option, developed by Google, is Flutter, the latter uses the Dart programming language, it is not very popular, but easy enough to learn. The main difference in Flutter is that it is a widget-based development approach and comes with many built-in UI components.

Obviously, for Android, there are other options, such as React Native and Ionic, but in this list, we are going to list the best courses for Java, Kotlin, and Flutter.
