This is the worst kind of pedantry. There is now code in a text file that wasn't there before. It doesn't really matter to me if they code came from human fingers, an auto generator tool, an LLM or a ouija board. It looks like written code and it compiles like written code - it's written code. You can rightly criticise the use of LLMs in many ways but it is more useful to focus on the actual reasons they cause harm t…

> it's amazing to use Claude to prompt an app into existence, and pretty frustrating when that app doesn't work right and Claude is all thumbs fixing the problem. Such an in interesting sentence. App that doesn't work doesn't seem like it's yet come into existence. This has been my (limited) experience so far. I haven't been able to get an AI/LLM to help me build an app. Even React apps it fails at. I have been able…

I've made a lot of apps with claude.e.g I made a pretty complex swiftui app recently even though I don't know swift. Usually you have to help Claude debug them and sometimes point it in the right direction.

Since the vast majority of Swift and SwiftUI documentation online is outdated, I've found that concatenating the best of "what's new in Swift 5.x / 6.x" blogs then asking it to organize that into a prompt for itself, then adding that to the system prompt, helps the LLM produce idiomatic and current code.

While these changes may require "new ways of thinking" in humans, the LLM seems to have these conceptual approaches embedded already thanks to other languages that did these things earlier. The what's new just shows it the syntax for these concepts in Swift.

It does seem like the same type of UI as v0.dev ("What do you want to do?") is a strange UI/UX for fixing a bug, although I see there is a way to import code. The ideal UI/UX seems to be a CLI tool or VS code extension where I give it access to the directory and describe the bug and it just figures out what to do

Yeah, we allow importing projects so you can fix bugs you've encountered elsewhere, but we want to streamline the app building process and the UX used in v0/Bolt etc is already really well done. We want this app building to be more reliable though, it's easy to hit bugs that prevent progression.

We're also interested in using our API with MCP so that e.g. Cursor could be used to fix bugs you're seeing locally, and plan to explore that angle before long.

You say it's called Nut because it's about cracking nuts. Wouldn't a truer reason be it's a play on bolt? (Nuts and bolts) I'd be interested to read a blog post or technical write up. I think conceptually it's an interesting idea

Well, it can be both. This post https://blog.replay.io/the-nut-api is the best technical overview of the API and discusses several examples.
