Introducing xcbolt!

A modern Xcode CLI and interactive TUI that humans and AI agents both love.

Claude Fable 5 is by far the most ridiculous model that makes me genuinely afraid for the future of software engineering.

I compiled the top 10 most unbelievable things I've seen Claude Fable 5 do today:

— Migrate a 50M line codebase from Stripe in a day (humans take 2mos)
— Draw amazing 3D graphics a) Boeing 747 b) space simulations with >5000 objects c) Minecraft roller coasters d) full photorealistic forest scenes e) NYC skyline f) stormy clouds)
— One-shot Pokemon FireRed the game
— Optimize a real world proprietary interaction net evaluator 10x more than the next best model, gpt5.5

AND it's about the same price as GPT 5.5 ($10/M input, $45/M output) vs Fable 5 ($10/M input, $50/M output) and 6x cheaper than GPT 5.5 Pro.

@lumendriada hopefully GPT 6 will be able to beat Fable...
at least I'm hopeful according to this vague post:

@robertcourson Feeling pretty good about things

[Vedran Burojević @vburojevic]

@thsottiaux @robertcourson man if you introduce a better model than Fable, and keep it under subscription, I will buy a 3rd Codex Pro subscription...

[Vedran Burojević @vburojevic]

@shadcn nice one! 🤝

[shadcn @shadcn]

You have Claude Fable for only a few days. Here's how to make the most of it.

Introducing /improve: use your most capable model to audit your codebase and write plans for cheaper models to execute later.

Studies your code, figures out bugs, perf, tech debt, missing tests, what to build and writes plans any agent can run.

@Dimillian Ask the model

[Jordan Morgan @JordanMorgan10]

Here are the skills that ship with Xcode 27.

Apple did a fantastic job with these (no surprise) from what I've poked around and looked at. Baseline SwiftUI guidance, and nuggets on how to use the new stuff like the reorderable APIs.

[Mark Gurman @markgurman]

Lol could they be any more blatant?

[Vedran Burojević @vburojevic]

@thekitze Apple - the Internet Explorer of AI

[OpenAI Developers @OpenAIDevs]

More of the iOS app loop, now inside Codex.

The Build iOS Apps plugin lets Codex view and test your iOS app in the in-app browser, open SwiftUI previews, and hot reload edits without leaving Codex.

[Vedran Burojević @vburojevic]

@rudrank it's amazing, try it out

[Vedran Burojević @vburojevic]

Ok, would anyone actually be interested in @herdrdev native iOS/macOS/iPadOS apps powered by Ghostty (libghostty)?

I’m building them and using them privately, but having second thoughts of putting the extra work into it to be production ready and open source.

Do you guys think herdr TUI is enough?

This is ghostty + herdr in screenshot below.

And thanks to @mitchellh and @lumendriada for building such amazing opensource.

[Vedran Burojević @vburojevic]

@maddada @trycua Cua is amazing

[Vedran Burojević @vburojevic]

I don’t get the current hate for @_HermesAgent and @Teknium and all the skill discussions (just turn off the ones you don’t want). Hermes is amazing, so don’t let all of this stop you from trying it out.

[Vedran Burojević @vburojevic]

@peduarte raycast v2 public/stable when?

[Vedran Burojević @vburojevic]

@maddada @DavidOndrej1 ooh, nice one!

[Vedran Burojević @vburojevic]

@NousResearch @StepFun_ai tried it, doesn’t seem very good with tool use

[Siro @Siron93]

2996 customers later, it’s time to release ScreensDesign V2 !

3 months of work.
A more complete library.
A truly agentic /create.

→ Research what works in real iOS apps
→ generate onboarding, paywalls, and full app flows
→ hand it to AI coding agents
→ Make the printer go brrrr

First 200 retweets+replies/DMs get free credits dm'ed ;)

@steipete I used cmux and it is awesome. Currently trying out https://t.co/g3wAgqj5oS and building native apps for it as a weekend project

[Vedran Burojević @vburojevic]

@thekitze Or https://t.co/XidrgbtXrI? Dibs on a free invite when you do it 😛

[Vedran Burojević @vburojevic]

@thekitze built supermac app with 999+ functionalities and subapps basically, mobile apps, MCP, browser extensions, api, website, etc… in like a few days…

And this is what AI agents can do for a senior engineer who knows his stuff and can utilize his knowledge…

So yeah, when someone says you can’t build it right with AI… skill issue…
