Key differences between Swift and Grain

CharacteristicSwiftGrain
SyntaxModern, concise, and expressive syntax inspired by languages like Python and Ruby; designed for readability and safety.Functional, ML-inspired syntax similar to OCaml and ReasonML; emphasizes immutability and pattern matching.
ParadigmMulti-paradigm: supports object-oriented, protocol-oriented, and functional programming.Purely functional: emphasizes immutability, first-class functions, and strong functional programming concepts.
TypingStatically typed with type inference; strong type safety and optionals for null safety.Statically typed with type inference; uses Hindley-Milner type system for strong type safety.
PerformanceHigh performance, compiled to native code (LLVM); suitable for production mobile and server applications.Compiles to WebAssembly for efficient execution in browsers and other WASM environments; performance is good for WASM but not as fast as native code.
Libraries and frameworksRich ecosystem, especially for Apple platforms (iOS, macOS); extensive standard library and third-party frameworks.Smaller ecosystem; limited libraries and frameworks, mostly focused on WebAssembly and functional programming.
Community and supportLarge, active community with strong support from Apple and open-source contributors.Small, niche community; primarily supported by enthusiasts and core maintainers.
Learning curveModerate; approachable for beginners, especially those familiar with modern programming languages.Steep; requires understanding of functional programming and ML-family languages.
