🏗️What if your whole stack was built with Swift?

Also totally agree on Xcode needing Linux as a run target — would be a game changer for server-side Swift workflows.

Swift.org Swift is a general-purpose programming language built using a modern approach to safety, performance, and software design patterns.

Note you need the swift.org open source toolchain — the Xcode one won't work. Once the Static Linux SDK is installed, you get fully statically linked ELF binaries with zero external dependencies, not even libc. Runs on any distro.

Swift.org Swift is a general-purpose programming language built using a modern approach to safety, performance, and software design patterns.

The key commands are:

swift build --swift-sdk x86_64-swift-linux-musl
swift build --swift-sdk aarch64-swift-linux-musl

To me it looked like that the github thing was prompt injection in the title but I may have mis understood. @robbinsa.me so why the lol?

So this validation on input can eliminate a rough agent from prompt injection as agents by nature need brought operation rights to be able to do there job you better know the instructions you give it are yours.

Its a mercel like tree that creates on every bit change a new hash of the tree of files in a folder. Hence giving you an ultra fast hash to verify input data into an agent you trust.

@robbinsa.me care to explain what you think it is then. In Mac OS tahoe this system is used to load criptex parts of the os for ai containing the local models. This is to prevent those models from being altered to protect against prompt injection.

Swift/JS interop used to mean "JSObject", "JSValue", and runtime surprises.

BridgeJS changes that: annotate your Swift, get typed glue code in both directions. Compile-time safe. Zero manual boilerplate. 🧵

For iterative ui testing. A thing ai needs to force it to actually build all the thinks it promised to build.

I tried antigravity but it produced numerous claims of success without any working implementation. Given its focus on eliminating precisely that I’m curious how you achieved it. We lack something like Playwright MCP to validate end-to-end autonomously native UI in apps. XCTests are very clunky

Some say Xcode previews replace unit tests 😵‍💫. We strongly disagree.

I'm seriously considering rebranding myself as a "cross-platform Swift developer" compared to "Apple platform developer". Swift in the cloud and on Android is doing amazing and for me this will be the future. 👨🏻‍💻

But I have a question when you use `swift build --build-system swiftbuild` you also have the problem?

I know compiling and talking about feelings, I must be nuts?! don't know...

More recently opensource swift only. I try to force all my projects to compile and now use the swift build --build-system swiftbuild to compile. It has a lot of issues but at least I have the feeling that xcode does not do some patch work and my final build feels more light.

This is such a stressfull thing for me. 10+ I started iOS development and loved xcode and objective-c. In some ways over the years I defended xcode way to long. I was really depressed when I discovered with swiftui xcode was not going anywhere. My salvation was moving to swift.

If you use Swift Macros in a library, use this script to remove 50 megs of junk that Xcode forces into your binaries:

Oh boy now you found a reason to buy m5 but wait for Mac Studio with at least 128gb unified memory. 😳
