Mobile development has become a key factor of business success in the digital era. Companies are investing heavily in mobile applications to stay competitive and reach out to potential customers. As a result, programming languages such as iOS, Android, Swift and Kotlin have become popular among developers.

iOS

iOS is a mobile operating system developed by Apple Inc. It is used for all Apple products such as iPhones, iPads, and iPods. iOS development is done using the Swift programming language. Swift is a powerful and intuitive language developed by Apple that is easy to learn and use. It is a modern language that is built with safety in mind. Here is a simple example of a „Hello World“ program written in Swift:

import UIKit

class AppDelegate: UIResponder, UIApplicationDelegate {

        return true
    }
}

Android

Android is a mobile operating system developed by Google. It is used for a variety of devices such as smartphones, tablets, and watches. Android development is done using the Kotlin programming language. Kotlin is a modern and concise language created by JetBrains that is interoperable with Java. It is designed to be safe and expressive, and is easy to learn and use. Here is a simple example of a „Hello World“ program written in Kotlin:

fun main(args : Array) {
    println("Hello, World!")
}

Conclusion

Mobile development is an important part of the digital era, and programming languages such as iOS, Android, Swift and Kotlin are essential tools for developers.
