Technologies supporting the development of mobile applications include programming languages like Swift for iOS and Kotlin for Android. Cross-platform frameworks such as React Native and Flutter allow developers to create apps that work on multiple operating systems from a single codebase. In addition, software development kits (SDKs) and application programming interfaces (APIs) provide essential tools and services to enhance app functionality. Cloud services also play an important role in mobile app development by offering data storage, authentication, and backend support, enabling efficient and scalable application performance.
