What Is Cross-Platform Development?

Cross-platform development is the practice of building a single application codebase that can run on multiple platforms, such as:

Android
iOS
Windows
macOS
Linux
Web Browsers

Instead of creating separate applications for each platform, developers write code once and deploy it everywhere.

Introduction

Traditionally, companies developed:

Android App → Java/Kotlin
iOS App → Swift/Objective-C

This required separate development teams, higher costs, and longer delivery times.

Cross-platform technologies solve this problem by allowing developers to share most of the code across multiple platforms.
