Swift's syntax prioritizes readability without sacrificing functionality. The language eliminates many of Objective-C's verbose requirements—semicolons are optional, and type inference reduces the need for explicit type declarations. Lyft's migration to Swift demonstrates this efficiency: their team reduced the codebase from 75,000 lines to fewer than 25,000 lines while maintaining identical functionality.

Safety features distinguish Swift from many other programming languages. The language incorporates several protective mechanisms:

• Automatic Reference Counting (ARC) manages memory allocation and deallocation
• Mandatory variable initialization prevents undefined behavior
• Array bounds checking eliminates buffer overflow vulnerabilities
• Optional types eliminate null pointer exceptions

Swift 6, released in 2025, introduced compile-time macros for reducing boilerplate code, improved compiler performance, and enhanced error diagnostics. The language maintains full interoperability with Objective-C, allowing teams to migrate existing projects incrementally rather than requiring complete rewrites.
