Last call for Agent Conf Call for Papers. Submissions close June 20. We're still looking for talks about vibe coding, agentic engineering fundamentals, orchestration & multi-agent systems, or adoption stories from teams already working with agents in practice. Link below 👇

ASC CLI gives agents a way to work with App Store Connect without clicking through the dashboard. In the next React Universe On Air, @grabbou.com talks with @rudrank.bsky.social about building release automation for agents, with agents. Premieres June 18 👇

When multiple teams are shipping into one banking app, delivery friction stops being a local problem. That is where platform thinking matters most: shared standards, stronger release paths, testing, and observability. We wrote about it on our blog ➡️ clstk.com/4vhCcds

We optimized self-hosted Gemma 4 31B for Apex, our specialized React Native coding model. The setup: vLLM, two-GPU tensor parallelism, KV cache tuning, context limits, and MTP speculative decoding. The result: up to 2.48x higher output-token throughput. Read more 👇 Link below

We’re building an AI-assisted migration workflow to React Native. It helps add React Native to an existing app, build the first proof of concept, and evaluate the ROI faster, with engineers still reviewing the work. Learn more in the article ⬇️

AI is making it easier to move through tasks without getting stuck on every small blocker, and it’s changing how teams work day to day. @thymikee.bsky.social and @zebenfeld.bsky.social talk about React Native, agents, verification, QA, and testing in the latest React Universe On Air. Link below 👇

A React Native sandbox can have its own JS runtime and still leak through shared native resources. We wrote about how turboModuleSubstitutions fixes that by swapping in sandbox-safe TurboModules for files, storage, and more, without changing sandbox JS. Check it out - Link below 👇

Expo Updates now works in Isolated Brownfield with Expo SDK 55. We put together a guide that covers: 🔹 iOS packaging with XCFrameworks 🔹 the current Android patch 🔹 end-to-end OTA update testing Useful if you’re shipping RN inside an existing native app. Check it out 👇 Link in the comments

The full episode is live. As AI speeds up code generation, engineering shifts toward judgment: what to trust, what to test, and what is safe to ship. React Native, QA, review, Agent Device, and agents with Zack Ebenfeld and Michał Pierzchała. Listen to the episode now 🎧 clstk.com/4907T1T

Agent writes code. You click around. Check logs. Report back. Repeat. Sounds familiar? In our latest podcast we chat with Zack Ebenfeld on how he adopted fully agentic SDLC pipeline in Total Wine & More app to ship faster while maintaining quality (hint: he uses agent-device). Tune in May 13, 5PM👇

Apple Foundation Models fit best in the supporting layer around mobile AI. Titles, summaries, rewrites, and labels are a good match for local execution. Long-context and heavier reasoning still belong in the cloud. We wrote about where that split works well on mobile. Link in the comments 👇

⏰ 5 PM CEST Zattoo on moving from multiple TV codebases to one shared React Native setup. • what it takes to get there • what changes for teams • delivery: months → ~week • handling platform differences Q&A included. Link in comments 👇
