Swift

Swift is a powerful, modern, and open-source programming language developed by Apple for iOS, macOS, watchOS, and tvOS development. Designed to be safe, fast, and expressive, Swift combines the performance of compiled languages with the ease of scripting languages. It improves upon Objective-C by offering memory safety, optionals to prevent null errors, and concise syntax. Swift is now the primary language for Apple app development, making it a must-learn for iOS and macOS developers.

Key Features:

• Optimized for Performance: Runs faster than Objective-C.

• Memory Safety & Optionals: Prevents runtime crashes.

• Interoperability with Objective-C: Supports legacy Apple codebases.

• Modern Syntax & Type Safety: Reduces development errors.

• First-Class iOS & macOS Support: Best language for Apple platforms.

Best Use Cases:

✔ Native iOS and macOS applications.
✔ High-performance applications requiring Apple’s Metal and ARKit.
✔ Apps needing seamless integration with Apple’s ecosystem.
✔ Cross-platform apps (via SwiftUI and Server-side Swift).
