- This is a very welcome improvement but I should note the title is a bit clickbaity: using Swift on e.g. Cursor was always possible, it's just that after Microsoft banned forks from accessing the official VSCode marketplace last year you started having to workaround it by downloading and installing the .vsix file manually. Having the extension on the Open VSX Registry sorts this out so you can now install it via the proper way once more. Very happy this finally happened!
- I'm building iOS apps without opening Xcode. All in VSCode and CLI build tools. This is excellent!
- This is huge, long time coming. Interested to see if there is SwiftUI support.
- This extension is for "pure" Swift development, not iOS development. I doubt the latter will ever officially happen. It's possible to make it work for iOS at an unofficial capacity though by hooking into the extension's LSP support. We did this at Spotify to enable iOS development in Cursor for Bazel iOS projects: https://github.com/spotify/sourcekit-bazel-bsp
- You also can't do Android (app) development outside Android Studio.
- As others have stated it's possible, but might be cumbersome.
I made an example of an iOS/Android monorepo with a shared Rust core a few months ago: https://github.com/Antonito/bazel-app-core-native-example/
You do need the Android SDK to build, Android Studio makes things easier (even though the Bazel IDE plugin is a whole other topic itself..) but isn't mandatory to develop or run your app.
- That's just untrue on the face of it. All of the build tools are open and cross-platform. Is there a specific piece of Android Studio that you require for Android app development?
- Not certain if this answers the question, but it seemed like you're generally expected to install Android Studio to get the correct build versions of all of the tools and libraries. I guess theoretically you could repackage them yourself, but also not entirely clear why you would—other than perhaps download size. The tools can be driven externally, once installed, but so could XCode projects (with `xcodebuild`).
- This is not an expectation, no. Libraries are managed via Gradle or whatever build system you use. Android-specific host tools are Gradle-managed, installed via the sdkmanager tool, or managed via other means; I maintain a repository to install them via Nix [0], and many Linux distributions package them. The Android Studio IDE is not required, and doing so would pretty much break everyone's CI setup.
- They've always offered a bundle of the command line tools separately to Android Studio:
https://developer.android.com/studio#command-line-tools-only
- Are you sure about that? Flutter development for Android works great in VS Code/Codium. The Android extension [0] for VS Code has also worked fine in the past on a small Java-based App for me.
Android Studio is a probably the best IDE for this usecase but is not the only way.

- Incorrect. You can (if you really want to) build an Android app without having any Google tools.
But even if you don't want to do any crazy stuff, Android SDK itself is just a bunch of Gradle scripts and Java apps. You can download and install them without any GUI in the way.
This is very common in CI/CD environments. Google provides a handy tool for that: https://developer.android.com/tools
Sorry, but Android and iOS are simply incomparable in their quality. Android SDK is a high-quality tool for developers that provides all the expected interfaces.
iOS SDK is a lock-in GUI hell that requires you to use a shitty macOS-only tool to even _upload_ apps to Apple Store. Never mind doing headless builds in CI/CD. Why that tool is shitty? It uses its own protocol for upload and doesn't do proper PMTU, so if you have a misconfigured MTU somewhere in the chain between you and Apple, uploads will just silently hang.
Edit: D'Oh, the correct URL for the sdkmanager is: https://developer.android.com/tools/sdkmanager
- On the contrary, commit your code to your GitHub repo, triggering Xcode cloud build to take it from there, build, test, deploy to TestFlight or store.
Found a bug while backpacking Sardinia? Edit the GitHub repo source on your phone, commit... hey, new build shipped.
See the App Store Connect mode: https://developer.apple.com/xcode-cloud/
- You can definitely avoid Xcode, what are you talking about?
- Just to nit pick a bit, that link is for Android Studio and downloads from the "Google for Developers" website, then instructs how to install and manage the the command line tools using the GUI
- Not trying to argue but you can indeed pretty much completely avoid Xcode at this point. I’ve been doing it the past few weeks, including pushing to my phone and AppStore connect
- what? this is super easy with vim and gradle CLI
- What's the point then? Because nobody use Swift outside of iOS app development.
- > Because nobody use Swift outside of iOS app development
Because that isn't true, people do use it outside of iOS app dev, and is becoming more true as time goes on to boot.
It's also a chicken-and-egg problem: no one will use Swift for non-iOS tasks if the tooling support isn't there. The more investment into it, the more it will be picked up for other tasks.
But it's been used outside of Apple-specific things since the early days in various niches.
- I've been migrating my DikuMUD (originally C) to Swift for years! It's been pretty fun and Swift is a great language for it
- No so straightforward, but there is project that parses xcodebuild logs and pass them to lsp to provide LSP for SwiftUI projects https://github.com/SolaWing/xcode-build-server
Also I build extra tooling to facilitate iOS development in VSCode https://github.com/sweetpad-dev/sweetpad
- Thanks for your great work on sweetpad. I’ve always been a bit curious where the name came from though.
- Sweet=sweeft=swift+pad?
- I hate that I need to create an Apple account (with email and phone verification) just to be able download the sdk to use MacOS APIs. To make things worse I tried for like one hour to create an account and couldn't because for some reason I was no receiving the verification email.
- What type of support do you mean? Language checking? Live previews?
- I think swift is a really great language from the design perspective.
What makes it unusable outside the apple ecosystem imho is that while the C interop is amazing on paper, it sucks hard in practice due to the abomination of pointer types they build in.
The "all pointers are evil" attitude doesn't help when you want to use a C library and noone will write rewrite all these libraries.
- Some recent fixes went into 6.2.3 which really help with C interop, this post shows what that looks like in practice https://www.swift.org/blog/improving-usability-of-c-librarie...
- yup, it got much better recently
- Not to be that agentic coding guy, but I think this will become less of a problem than our historic biases suggest.
For context, I just built a streaming markdown renderer in Swift because there wasn’t an existing open source package that met my needs, something that would have taken me weeks/months previously (I’m not a Swift dev).
Porting all the C libraries you need isn’t necessarily an overnight task, but it’s no longer an insurmountable mountain in terms of dev time.
- My favorite part is the AI will still estimate projects in human-time.
“You’re looking at a multi-week refactor” aaaaand it’s done
- Yeah lol. “I estimate this will take 15-20 days” I do it in like 5 hours lol
- It's not necessary to rewrite perfectly fine libraries written by exceptional programmers. And whoever thinks it is an easy task (sorry rust guys) is severely suffering from the dunning-kruger effect.
- Very high quality comment that is being downvoted unfairly because it defends AI. HN is on the wrong side of history on this one.
- But can I develop iOS apps with vim? As in, easy to execute commands for debugging, running app and tests?
- Yes, provided you are running vim on macOS, and calling into the xcode command line tooling.
- If you’re willing to try Neovim I’ve been using xcodebuild.nvim for a couple of years (for macOS not iOS, but they’re both supported).
- Yes, But an iOS app requires a helluva lot more than just the Swift language. For example, Metal has zero support so you have to use ft=cpp and disable lsp diagnostics. And you can completely forget Xcode’s wonderful Metal debugger entirely.
Otherwise swift works just like any other clang/llvm project and the tooling is basically the same.
- i was hoping this was going to be AppCode rising from the grave but nah it's just more rebranded versions of VSCode. nothing new here
- The free Kotlin Multiplatorm plugin provides 1st class Swift support in IntelliJ IDEA. It’s heavily based on old AppCode codebase.
- Use swift as a scripting language without the slow start time:
Swift Caching Compiler - https://github.com/jrz/tools
- Is “$0” (`argv[0]`) correct when the pre-compiled binary is launched instead of the script?
- I recently started to enjoy working in Xcode more than before, using Swift. Not sure what changed, but it seems more responsive for lack of a better expression.
- Little by little, Xcode is making progress. Probably a lot of the improvements come from the open-source and actual work on its build system… It’s still far from perfect, but at least it’s getting better.
- Is there an open—source Swift IDE that can modify itself without restarting? (written in Swift) I loved Oberon µSystems Oberon/F aka Component Pascal for that capability.
Or am I going to have to vibe-code one.
- That is a very specific set of requirements. I doubt it.
- If you could reimplement Emacs in Swift that’d be great
- Now if only they'd open up iOS development so we can get AppCode back.
The primary thing keeping me away from trying it again is I have to use Xcode instead of my beloved JetBrains IDEs where I know all the keyboard shortcuts.
- Everyone should post to open-vsx by default.
- The loss of AppCode from Jetbrains was a huge blow to my motivation to continue working with Swift. Xcode just can't compare.
- Apparently most folks were happy enough with XCode and didn't bother to buy AppCode licenses, hence why JetBrains gave up on it.
- I've recently been using this plugin [1], which is still under development but is an adequate stopgap until a better solution comes along.

- [flagged]
- I don't even see the code. All I see is blonde, brunette, redhead.
- What the heck type of software are you shipping that you can just avoid looking at the slop the LLM serves you?
- The person you are replying to lives in the best of all possible worlds. I'm sure all is for the best within the code his LLM generates.
- We’ve used SweetPad and it worked fine for us, so this doesn’t change much.
- TLDR: same VScode extension now listed on OpenVSX registry, for Eclipse Theia et al.
But it's unclear if they tested it. For me, it fails basic configuration steps on the simplest project. Plugin compatibility between VSCode and others seems iffy.
Couple this with Xcode 26.4 AI lacking agentic features and you get Swift programmers being left behind.
