Swift is a more convenient Rust (2023)

📝 Discussion Summary (Click to expand)

Top 5 themes from the discussion

# Theme Key points & representative quotes
1 Swift vs. Rust – ergonomics vs. safety “Swift is more convenient than Rust” (dagmx) – “I find writing Swift is faster for me, and it’s easier to learn for people than Rust.”
“Rust is more convenient than Swift” (killingtime74) – “I would rather use Rust for the fact it's development is not tied to a big tech company.”
2 Apple’s ownership of Swift – risk of abandonment “Apple was the primary and only major sponsor of Objective‑C… Apple dropping support” (kibwen) – “Being tied so closely to Apple is an existential risk for Swift.”
“If Apple abandoned Swift tomorrow the language would almost certainly wither and die” (afavour)
3 Tooling & IDE pain points “Xcode is a rough IDE that has a hard time at scale” (JackYoustra) – “It has a special entitlement so you can’t even binary patch it if you want to fix it.”
“SPM is fine for most Swift and then fully enraging when you have a slightly divergent use case” (plagiarist) – “It’s a lot of friction.”
4 Cross‑platform maturity & ecosystem “Swift is becoming increasingly a good cross‑platform language” (mogoh) – “But the libraries, tools, and documentation still assume you use an Apple platform.”
“Rust’s ecosystem on Linux is fantastic” (rednafi) – “Swift’s cross‑platform story is still a long way off.”
5 Memory management & concurrency “ARC is deterministic and more power‑efficient than GC” (astrange) – “Swift’s reference counting still makes it hard to reason about memory.”
“Rust’s ownership model protects you from the footguns of actors and Tasks in Swift” (isodev) – “Rust makes most mistakes a build‑time error.”

These five themes capture the bulk of the debate: how Swift stacks up against Rust, the perceived risk of Apple’s control, the frustration with tooling, the state of Swift’s cross‑platform ecosystem, and the differences in memory‑management and concurrency models.


🚀 Project Ideas

SwiftX IDE

Summary

  • A lightweight, cross‑platform Swift IDE built on the Language Server Protocol that replaces Xcode for most workflows.
  • Provides fast incremental builds, integrated debugger, profiling, and seamless SPM/CMake/C++ interop.

Details

Key Value
Target Audience Swift developers on macOS, Linux, and Windows who need a faster, more reliable IDE than Xcode.
Core Feature LSP‑based editor with on‑the‑fly type checking, incremental compilation, and a built‑in debugger that works on all platforms.
Tech Stack Rust for the core compiler wrapper, TypeScript/React for the UI, SwiftPM + CMake integration, LLDB for debugging.
Difficulty High
Monetization Revenue‑ready: subscription with free tier for open‑source projects.

Notes

  • Xcode “is awful” and “chokes on package refreshes” (user xjayd16). SwiftX solves this with a lightweight build system.
  • Supports SwiftUI debugging on Linux/Windows, addressing the “no good tooling” complaint.
  • Offers a plugin system so teams can add custom linting or code generation.

SwiftCargo

Summary

  • A Cargo‑style package manager for Swift that adds C/C++ dependency resolution, vcpkg/CMake support, and lockfile determinism.
  • Makes Swift projects feel like Rust projects in terms of dependency handling.

Details

Key Value
Target Audience Swift developers who struggle with SPM’s lack of C/C++ support and slow dependency resolution.
Core Feature swift-cargo CLI that resolves dependencies via Cargo, vcpkg, or CMake, generates SPM manifests, and caches builds.
Tech Stack Rust for the CLI, JSON/YAML for manifests, integration with SwiftPM and CMake.
Difficulty Medium
Monetization Hobby

Notes

  • Users complain “SPM is much easier to work with than Cargo” but “SPM can’t use vcpkg” (ethin). SwiftCargo bridges that gap.
  • Provides deterministic builds with lockfiles, a feature missing in SPM.
  • Enables cross‑platform builds on Windows/Linux by delegating native dependency resolution to Cargo/vcpkg.

SwiftCrossLib

Summary

  • A curated registry and CI service that hosts pre‑built Swift packages for Windows, Linux, and Android, with comprehensive documentation and a simple install command.
  • Eliminates the “no libraries on Windows” pain point.

Details

Key Value
Target Audience Swift developers targeting non‑Apple platforms who need ready‑to‑use libraries.
Core Feature swiftcross install <pkg> that pulls a pre‑built binary from the registry, verifies signatures, and injects it into the project.
Tech Stack Go for the registry server, Docker for CI builds, SwiftPM for packaging, GitHub Actions for CI.
Difficulty Medium
Monetization Revenue‑ready: paid tier for private packages and priority builds.

Notes

  • “Swift has little to no toolchain support for less‑common platforms” (csmantle). SwiftCrossLib provides binaries for those platforms.
  • Users can browse a web UI to see supported OSes, versions, and dependency graphs.
  • Encourages community contributions by providing a simple “publish” workflow.

SwiftLeakGuard

Summary

  • A memory profiling and leak detection tool for Swift that integrates with LSP and works on Linux/Windows.
  • Detects ARC cycles, leaks, and provides actionable suggestions.

Details

Key Value
Target Audience Swift developers dealing with “memory leaks in SwiftUI” and “ARC cycle detection” issues.
Core Feature Real‑time memory usage dashboard, cycle detection, and automated refactoring suggestions.
Tech Stack Rust for the core analysis engine, Swift for the LSP plugin, WebAssembly for the UI, LLDB for runtime introspection.
Difficulty High
Monetization Revenue‑ready: subscription with free tier for open‑source projects.

Notes

  • “I have leaks that I still haven’t been able to find” (atombender). SwiftLeakGuard visualizes ARC reference graphs.
  • Works on all platforms, solving the “no good tooling on Linux/Windows” complaint.
  • Integrates with existing editors (VS Code, Helix, Neovim) via LSP, so developers can stay in their preferred environment.
