Key differences between Swift and Gleam
| Characteristic | Swift | Gleam |
|---|---|---|
| Syntax | C-like, modern, concise, and expressive with familiar curly braces and type inference. | Erlang/ML-inspired, indentation-based, minimalistic, and designed for clarity and safety. |
| Paradigm | Multi-paradigm: supports object-oriented, protocol-oriented, and functional programming. | Purely functional, emphasizing immutability and strong static typing. |
| Typing | Statically typed with type inference, optionals, and strong type safety. | Statically typed with strong, sound type system and no nulls or runtime type errors. |
| Performance | High performance, compiled to native code, suitable for system and application development. | Compiles to Erlang or JavaScript, performance depends on BEAM VM or JS engine; optimized for reliability over raw speed. |
| Libraries and frameworks | Rich ecosystem, especially for iOS/macOS development (e.g., SwiftUI, UIKit, Vapor). | Smaller ecosystem, can use Erlang/Elixir libraries, but fewer native Gleam libraries and frameworks. |
| Community and support | Large, active community with strong support from Apple and extensive learning resources. | Small but growing community, mostly open source contributors, limited resources compared to Swift. |
| Learning curve | Moderate; easier for those familiar with C-like languages, but some advanced features can be complex. | Gentle for those new to functional programming, but may be challenging for those used to imperative or OOP languages. |
