Key differences between Swift and Zig

CharacteristicSwiftZig
SyntaxModern, concise, influenced by Objective-C and scripting languages; uses clear, expressive syntax.Minimalist, C-like, explicit; prioritizes clarity and control with little syntactic sugar.
ParadigmMulti-paradigm: supports object-oriented, protocol-oriented, and functional programming.Procedural and imperative; does not support OOP or functional paradigms natively.
TypingStatically typed with strong type inference and safety features.Statically typed with explicit types and compile-time evaluation; focuses on safety and predictability.
PerformanceHigh performance, optimized for Apple platforms; uses ARC for memory management.Very high performance, close to C; manual memory management, no hidden control flow.
Libraries and frameworksRich ecosystem, especially for iOS/macOS development (e.g., SwiftUI, Foundation).Smaller ecosystem; can use C libraries easily but lacks extensive native libraries.
Community and supportLarge, active community; strong support from Apple and open-source contributors.Growing but smaller community; mostly driven by open-source contributors.
Learning curveBeginner-friendly, especially for those familiar with modern languages; good documentation.Steeper learning curve due to low-level concepts and manual memory management.
