In the long run the approach Svelte takes seems very promising so I've kept an eye on it for a while now. I took umbrage at the snooty messaging towards a browser in a tool pitched as a way to "build production-grade websites".
Sure but the "snooty messaging" you're commenting on is from their tutorial, which is used to conveniently learn the framework in the browser.
This has nothing to do with Sveltekit itself. You can download a demo repo, enter "npm run dev" and see that it works on Safari without any issues. Hell, I've deployed ecommerce sites using Sveltekit used by 500k people/month where 60% of visitors are on mobile Safari without any issues.
So when a product is posted that you are unfamiliar with, maybe try giving it more that 30 seconds of consideration before dismissing it due to something completely unrelated to the product itself.
