Technologies that support mobile app development frameworks include programming languages such as Java and Swift, as well as cross-platform tools like React Native and Flutter. These tools provide developers with pre-built components, access to native features, and a streamlined development process. Additionally, cloud services like Firebase offer backend support, real-time data synchronization, and user authentication, enhancing app functionality. Integrated development environments (IDEs) further facilitate coding, testing, and deployment. Together, these technologies create a comprehensive ecosystem that simplifies mobile app creation.
