Modern Development Platforms and Languages

Today’s mobile application development is divided into two main categories:

1. Native Development
   • iOS: Developed using Swift or Objective-C in Xcode.
   • Android: Built with Kotlin or Java using Android Studio.
     Native apps provide high performance and deep integration with device hardware but require separate development efforts for each platform.
2. Cross-Platform Development
   • Popular frameworks: Flutter, React Native, Xamarin, and Ionic.
   • These allow developers to write code once and deploy across both iOS and Android.
     Cross-platform development significantly reduces time and cost but may have limitations in performance for highly complex apps.

Key Components of App Development

1. Front-End Development
   This involves the user interface (UI) and user experience (UX) design — how the app looks and feels.
2. Back-End Development
   This includes servers, databases, APIs, and cloud services that support the app’s functionality behind the scenes.
3. APIs and Integrations
   Apps often connect with third-party services such as Google Maps, payment gateways, and social media platforms.
4. Testing and QA
   Ensuring the app works across multiple devices, screen sizes, and OS versions is crucial before launch.
