WWDC 2026: Device Hub and what it means for CI/CD

At WWDC 2026, Apple shipped a long list of changes, and we covered the ones flying under the radar in our round-up of the less-reported announcements. One of them deserves a closer look on its own: the way Xcode 27 reshapes how developers manage devices and simulators. Xcode 27 ships with a new app called Device Hub, replacing Simulator.app found in older Xcodes. Device Hub is where both physical devices and simulators can be managed from now on.

WWDC 2026: Under-the-radar announcements for iOS developers

WWDC 2026 delivered plenty to talk about. Apple's renewed AI push, Xcode 27 (that we shipped to customers in beta within 24 hours of the keynote!), and refreshing Liquid Glass. It also delivered a notable absence: no M5 Mac minis yet, which we covered separately. Now that the dust has settled, Bitrise’s Ben Boral went looking for the announcements that slipped past the highlight reel. If you're a mobile developer, these three are worth your time.

Maven Central rate limits: What you need to know

Maven Central introduced rate limits for high volume users. Bitrise is protecting its users from rate limiting errors on dependency resolution by hosting a repository manager, a sort of pull-through cache, to reduce load on Maven Central and provide faster dependency downloads. This is enabled by default at not additional cost for all Bitrise hosted builds.

The most reliable Mac fleet for GitHub Actions: M4 Pro available now

Apple didn't announce the M5 Pro at WWDC, and the M4 Pro Mac Mini industry shortage isn't going anywhere either. Neither should affect your CI. Apple pulled the base model from its store and discontinued the 32GB config. What's still available ships in weeks with some configs months out. Resellers are asking $979 for $599 machines and Tim Cook confirmed the constraints will last several more months.

Ship iOS and Android builds twice as fast on GitHub Actions

Last year, Nathan Hillyer's iOS platform engineering team at ForeFlight had self-hosted Mac hardware in their office, two engineers keeping them alive, and a codebase with over 2 million lines of Objective-C, Swift, and C++. Every Xcode update was a fire drill. Every capacity spike during a merge meant somebody was physically racking hardware in the Austin office. ForeFlight didn't want a new CI system. They wanted to stop being a data centre.

Open Source Registries Are Changing: Here's How Bitrise Keeps Your Builds Running

There is a shift happening in a previously quiet corner of the open source community. You may have experienced this in your own Android builds with an HTTP 429 ("Too Many Requests") error during dependency resolution from Maven Central. Over a period of a few days in late April to early May 2026, a subset of Bitrise users experienced these errors. Here's what happened, what we did about it, and what it means for you.

Build Cache for React Native setup guide

Learn how to leverage Bitrise Build Cache to reuse build outputs and compilation data in your React Native projects.

CopyFail, Local Privilege Escalation, and what Bitrise customers should know

With all the online chatter about Copy Fail, DirtyFrag, and Fragnesia, we prepared this simple explainer about what these local privilege escalation vulnerabilities are and how they affect Bitrise customers. Bitrise provides a full-stack, vertically integrated mobile DevOps solution that unites the tools, processes and testing frameworks engineering teams need to build best-in-class mobile experiences. Over 400,000 developers use Bitrise’s products: Bitrise CI, Build Cache, Release Management, and Insights.

Q&A: Changing the game for creators: how Substack doubled mobile build speed with Bitrise

When Substack first launched in 2017, the company set out to give writers a better business model, built on subscriptions and direct relationships with readers. Since then, Substack has expanded into multi-format publishing across text, audio, and video, while building powerful tools for community and discovery, for creators, writers, and thinkers of all kinds.

What App Stores allow with OTA updates: Apple and Google policy explained

A critical bug is live in production. Your fix is ready. And now your team is staring at a potential multi-day wait for app store review. This is exactly what over-the-air (OTA) updates are designed to solve. Tools like Expo EAS Update, CodePush, Shorebird, Revopush or Stallion make it easy to push updates directly to users’ devices. But OTA updates don't bypass app store rules, they operate within boundaries that both Apple and Google have defined.
