‍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.

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.

AI-assisted builds grew 164x in a year. The rate teams ship to users fell by a fifth. Arpad Kun, VP of Engineering and Infrastructure at Bitrise, on the gap that opened up in between, and what his team built to close it.

‍An outdated build environment can slow down your team, introduce security risks, and cause hard-to-debug issues. With our upgraded Linux stacks, you get a faster, more secure, and fully maintained build environment: so your team can focus on shipping great apps, rather than managing infrastructure. Ubuntu Noble 24.04 - Bitrise 2025 Edition is now available as a stable stack, bringing Noble Numbat as the default Ubuntu version to Bitrise.

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 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.

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.

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.

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.
