React Universe On Air

Rudrank Riyam joins React Universe On Air to talk about App Store Connect CLI, an open-source tool for automating App Store Connect workflows without living in the dashboard.

What started as a way to pull TestFlight feedback turned into a broader interface for metadata, submissions, localization, analytics, reviews, and release operations. Mike Grabowski and Rudrank discuss why these workflows are a strong fit for CLI automation, why Go became the right language for an agent-built tool, how teams are using it in CI/CD and agent workflows, and what changes when multiple coding agents build against the same codebase.

They also get into code structure, command design, agents.md, public vs. private App Store Connect endpoints, and what changed after Rork acquired the project while keeping it open source.

What we cover:

- Why App Store Connect workflows are a good fit for CLI automation
- How the tool handles TestFlight feedback, metadata, localization, analytics, reviews, and submissions
- Why Rudrank chose Go over Swift for an agent-built CLI
- What he learned from running multiple agents against one open-source project
- How clear structure and command naming make a codebase easier for both humans and agents
- What Rork’s acquisition means for the project going forward

Guest: Rudrank Riyam is a software engineer at Rork and the creator of App Store Connect CLI. He works at the intersection of Apple development, release tooling, and agentic workflows.

Zack Ebenfeld joins Michał Pierzchała to talk about AI-assisted coding, testing, QA, code review, and why verification matters more than ever in mobile workflows. It is a practical conversation about trust, feedback loops, and how engineering work is shifting from pure implementation toward judgment, architecture, and product thinking.

What happens when you combine voice agents and teddy bears? A hands-on look at local-first systems, voice AI, and security lessons from poking real apps. Kraen Hansen and Ola Desmurs-Linczewska talk about Software, AI Agents, parenting, stoicism and more!

Vercel’s v0 iOS app is built with React Native, but it looks and feels like a fully native iOS product.

In this episode of React Universe On Air, we go deep into how the v0 mobile app was built: from choosing Expo and going iOS-first, to writing native modules, fixing low-level React Native issues, and upstreaming improvements back to the ecosystem. This is a hands-on engineering conversation with Fernando Rojo, Szymon Rybczak, and Oskar kwaśniewski about real trade-offs, real constraints, and what it takes to ship a polished app under real deadlines.

This year, React Universe On Air is doing something different for Christmas. No guests, demos, or framework updates. Instead, Ola Desmurs Linczewska tells a Christmas story.

A (Secure) Christmas Carol is a holiday fairytale for JavaScript and React Native developers. Set on Christmas Eve, it follows Npmezer Scrooge, a senior engineer who believes deadlines matter more than holidays, and warnings can always wait.

Over the course of one long winter night, he’s visited by unexpected guides who show him what his choices look like across time: the optimism of the past, the quiet damage of the present, and a future no one wants.

All technical details, real-world security issues, and references mentioned in the story are explained in the show notes 📚  https://clstk.com/4pEVYwv

We’ll be back in January with regular episodes. Until then, stay kind, stay curious, and have yourself a very merry Christmas.
