I wouldn't describe Swift itself as having so much potential: I loved it and advocated for it, for years. After getting more experience on other platforms and having time to watch how it evolved, or didn't as per TFA, it's...okay to mediocre compared to peers - Kotlin, Dart, Python come to mind.

If Foundation was genuinely cross platform and open source, that description becomes more plausible for at least some subset of engineers. * (for non-Apple devs, Foundation ~= Apple's stdlib, things like dateformatting)

I don't mean to be argumentative, I'm genuinely curious what it looks like through someone else's eyes and the only way to start that conversation is taking an opposing position.

I am familiar with an argument it's better than Rust, but I'd very curious to understand if "better than" is "easier to pick up" or "better at the things people use Rust for": i.e. I bet it is easier to read & write, but AFAIK it's missing a whole lot of what I'll call "necessary footguns for performance" that Rust offers.

* IIRC there is a open source Foundation intended for Linux? but sort of just thrown at the community to build.

I'm not deep in Swift, but this would make it seem a reimplementation of Foundation is open source: https://github.com/apple/swift-corelibs-foundation/tree/main

What is there to say in favor of Dart? Isn’t it a “good enough” middle-of-the-road language?

It is truly cross platform, unlike Swift, has great UI going for it that you can use everywhere and improved greatly as a language in recent years while Swift continued siloing itself in Mac world.

Dart might not break world records for most innovative or performant general purpose language, but it’s a completely different language from 6 years ago.

Pretty much, which I love. Opinionated TL;Dr: Kotlin without the duplicates of Java classes, or 20 different inscrutable functional operators. Swift without the compile times and architecture astronaut stuff that infected stuff built on it and makes apple reinvent it every 2-4 years, c.f. async/SwiftUI. Genuinely cross platform, both in terms of code* and UI** It's indistinguishable from native in the way that's meaningful to users (note it's AOT on not-web, not JIT, and does a bunch of obvious stuff, use the platform text renderer, scollbars, scroll velocity, etc)

* I'm too old now, 36, and you have no idea how much I roll my eyes internally at hopeful invocations of 'man if only Swift was cross platform / look apple did this so swift is coming cross platform. All the "SwiftUI web is clearly coming" wish casting from big names in the Apple dev community who should have known better broke me.

** the mish mash of bad, competing solutions to bringing iOS UI cross Apple platforms forfeits the core premise of an Apple-values inheriting dev: I'm infinitely better off having a base UI engine that renders the same stuff on each platform than a shim that renders and acts differently

Dart doesn't get a lot of respect around here but after working with it every day for the last few months I've come to really appreciate how fast it compiles and reloads. It's a major productivity boost. Other comparably expressive mainstream languages are so much slower to iterate with.

Im surprised to see Python in that list. Swift being type safe and Python not puts Swift miles ahead.

Python is the new Perl. Heck its the lingua franca of ML / AI and has been for data science for a while. Dynamic types dont mean you cannot compete with a typed language. Python has type hints which gives the benefit people are usually after, catching bugs / issues ahead of time.

Theres a library for just about everything in Python. I dont know that I can say that about Swift.

One of those awkward things where I don't like it, and wouldn't go back to nulls that blow up. But as far as being the right tool/accessible it ended up winning use cases where I expected scripting and Playgrounds to have mindshare

Playgrounds is so painfully slow that you can't really "play" with it at all.

Mypy is non-nullable, as far as I know. Unless you do Type | None. (Or was it TS?)

wiseowise1y ago

Python has Mypy (yes, it’s good enough, don’t bother arguing with me that’s it’s not “real”) and ecosystem is leagues above anything Swift can offer.
