Swift name, Forth game, Mac pain
SwiftForth IDE for Windows, Linux, macOS
New Forth tool lands everywhere—name and Mac support spark chaos
TLDR: SwiftForth, a Forth programming toolkit, launched on Windows, macOS, and Linux with built‑in tools and docs. Commenters joked about the misleading “Swift” name, criticized Intel‑only Mac support and command‑line-only Unix editions, and marveled at object‑oriented Forth—proof that retro tech can still spark modern drama
SwiftForth just dropped a cross‑platform dev tool for the retro‑cool Forth language—GUI on Windows, command line on macOS and Linux, no extra compiler needed, and even full source if you buy in. But the comment section immediately stole the show. The name “SwiftForth” sent half the crowd sprinting in the wrong direction—several thought it was built with Apple’s Swift or SwiftUI. Plot twist: it’s Forth, a minimalist old‑school language that still has diehards. Cue the memes and facepalms.
Then the real drama hit: Mac folks groaned that it appears to be Intel‑only on macOS, with one user calling that “one of the decisions of all time.” Translation: on newer Apple chips, that’s a headache. Meanwhile, Windows gets the fancy GUI while Mac/Linux users live in the terminal, and the peanut gallery noticed.
There’s curiosity, too. Some praised how it easily taps system features, ships robust docs (yep, PDFs), and even boasts SWOOP—its take on object‑oriented Forth. One commenter stumbled on the site’s quirky “if you’re looking for the debt relief company…” line and the Featured Forth Apps page, adding to the “what is happening but I kinda love it” vibe. Newcomers asked which Forth to pick amid a “deluge” of recent releases. Verdict from the crowd: fascinating throwback, confusing name, spicy Mac drama, surprisingly lively energy
