SwiftForth

SwiftForth is a Forth system designed to run on the Swift programming language. It provides a runtime and development tools that enable writing and executing Forth code within a Swift-based environment. The core components include a Forth dictionary of words, a data and return stack, and an execution model in which words are defined and composed to perform operations. It supports standard Forth features such as conditionals, loops, and compilation of new words, with extensions that facilitate interoperability with Swift code and native APIs when available. The project emphasizes portability across Swift-supported platforms and aims to be usable for prototyping, education, and embedding a programmable layer in Swift applications. Users interact with SwiftForth through an interactive prompt or through using included tooling to compile and load new words. The project has a community of users and contributors who maintain documentation and sample programs. See also: Forth, Swift, Forth implementations.
