React Native debugging poses particular challenges due to the framework’s cross-platform codebase, which combines JavaScript and native platform components. However, an effective React debugging regime will enable you to proactively fix issues in both production and development. Today’s post will give you the fundamentals to build that regime, showing you: Want to jump to a specific bit of knowledge? Here’s the full list of contents.

A React Native build is really two builds stacked on top of each other. On Android, Gradle compiles your Kotlin and Java, then drops down into cmake and ndk-build to compile the C++ that ships inside Hermes, Folly, ReactCommon, and your own turbo modules. On iOS, Xcode does the equivalent: Swift and Objective-C on top, the same C++ underneath via Clang. Two build systems, two languages on top, one shared set of C++ underneath.

‍Build Cache can meaningfully shorten CI feedback loops, but only if it’s connected to workflows where it’ll actually make a difference. So how do you figure out which workflows will benefit? That’s the part that’s been easy to get wrong — until now. Quick Connect is a new feature that takes the guesswork out of estimating time savings: it looks at your last 30 days of build data and surfaces the workflows that will benefit themost from caching.

Debug logging is a particular form of logging that records detailed information about how an application behaves during execution, so we can identify, understand, and fix issues. This guide will give you a rookie-to-pro guide to debug logging, showing you: By the end, you will have a clear, practical approach to using debug logs effectively in real applications.

TL;DR AI is no longer the future. It is the present. Global enterprise AI spending will roughly reach $2.6 trillion in 2026, generative AI now touches 65% of Fortune 500 workflows, and your competitors in both the mid-market and enterprise space are deploying agents, copilots, and predictive models at a pace that would have seemed impossible 3 years ago.

Having maintained a CodePush fork for 18 months and served billions of updates, we decided it was time for an overhaul. We’re big fans of CodePush, and it was a great benefit to the React Native community. But, it was written in 2015 and had some weaknesses. The biggest of these was architectural, with limitations in how update checks and release metadata could scale. The result, Codemagic Patch, is now public and available to self-host.

WWDC 2026 delivered plenty for app developers to talk about, but some of the most consequential announcements were aimed squarely at the people running the infrastructure underneath. We've already covered the under-the-radar announcements for iOS developers and what Xcode 27's Device Hub means for CI/CD. This one is for the fleet operators. If you run Mac infrastructure at any scale, the Virtualization framework is already part of your life. On Apple Silicon, it's the only way to run a macOS guest.

If you're building iOS apps on Bitrise and using one of the Xcode 26 edge stacks, you must switch to the Xcode 26 stable stack before July 31, 2026.

Every CIO has a slide deck full of AI pilots by now. A chatbot that answers FAQs. A copilot that drafts emails. An agent that summarizes meetings and files the notes nobody reads. The demos get applause in the boardroom, the budget gets approved for “phase two,” and then largely nothing happens. The pilot quietly lives on in a sandbox, forever 80% done, forever six weeks from launch. If that sounds familiar, you are not behind. You are, statistically, in the majority.
