The programming languages primarily used for mobile development include Flutter (Dart), Kotlin (Android), and Swift (iOS). Each language is tailored for specific platforms, facilitating the creation of high-quality mobile applications. Flutter’s capability for cross-platform development allows developers to write code once and deploy it on both Android and iOS, enhancing productivity. Kotlin is recognized for its concise syntax and seamless integration with Android Studio, while Swift remains the go-to for native iOS app development, leveraging Apple’s resources effectively.
