June 2026 Summaries

Bitrise has launched Remote Dev Environments (RDE) in beta to streamline development by allowing developers and coding agents to work in the same environment as the Bitrise CI and Build Hub, eliminating the discrepancies that arise when local development environments differ from CI environments. By offering the same virtual machines, stacks, and cache infrastructure used in Bitrise's CI builds, RDE ensures consistent execution and testing, thus removing the common "works on my machine" problem. This approach provides developers with the benefits of real macOS systems on Apple Silicon, complete with the Xcode toolchain and build caching for Bazel, Gradle, and Xcode, and enables the use of tools like Claude Code and Codex. The integration simplifies the configuration process, as developers can connect using VS Code, JetBrains, or SSH, and orchestrate parallel agents through an open-source MCP server, leveraging the existing security infrastructure previously approved for Bitrise.

Developers building iOS apps on Bitrise using Xcode 26 edge stacks must transition to the Xcode 26 stable stacks by July 31, 2026, as Bitrise will retire all Xcode 26 edge stacks on that date. These edge stacks are designed for short-term use to test upcoming Xcode versions and are frequently updated with the latest tools, including beta versions, unlike the stable stacks which provide long-term reliability with only critical security updates. To ensure seamless continuity, users should check and update their workflows, replacing any edge stack references in their configurations with the stable stack equivalents or the new Xcode 27 edge stack, depending on their needs. If changes are not made by the deadline, Bitrise will automatically migrate builds stored on bitrise.io to the appropriate stable stack to prevent disruption, but users with configurations in git repositories will need to manually update their stack targets to avoid build failures. Once changes are made, running a test build can confirm the successful transition, which is crucial for maintaining consistent and reliable production CI workflows.

Bitrise has introduced an upgraded build environment with the release of Ubuntu Noble 24.04 - Bitrise 2025 Edition as the new stable stack, enhancing speed, security, and reliability for continuous integration and continuous deployment (CI/CD) pipelines. The update includes a range of new and updated preinstalled tools, such as Ruby 3.4, Node 24, and Go 1.25, aiming to streamline the build process for mobile app developers. Meanwhile, the previous stable stack, Ubuntu 22.04 for Android & Docker, is now frozen and will be removed in April 2027, prompting users to transition to the new stack in advance. The introduction of Ubuntu Resolute 26.04 - Bitrise 2026 Edition as an edge stack indicates Bitrise's commitment to regularly updating its Linux stacks in alignment with the latest Ubuntu LTS versions. These changes ensure that developers can focus on app development rather than managing infrastructure, with Bitrise providing resources to facilitate a smooth transition to the new environment.

Despite the considerable changes and growth, he hopes that the core values of open communication and community will remain unchanged.

At WWDC 2026, Apple introduced significant changes with Xcode 27, notably replacing Simulator.app with a new application called Device Hub, which unifies the management of both physical devices and simulators. This update extends the capabilities of Apple's existing CLI tool, devicectl, to handle simulators, aligning the management interface across both device types. Device Hub, which can run standalone or bundled with Xcode 27, features a three-part interface—Sidebar, Canvas, and Inspector—that streamlines settings adjustments and diagnostics, enhancing developers' efficiency in local workflows. This unified approach is particularly beneficial for CI/CD processes, enabling consistent simulator configurations and reducing manual setup time. While some new simulator capabilities in devicectl are still under development, the tool offers consistent syntax and JSON output support, promising a more streamlined workflow for developers. As Xcode 27 is still in beta, some features are expected to be fully functional in future updates, but the current integration already facilitates more reliable testing and automation.

At WWDC 2026, Apple unveiled significant updates and tools for developers, with a notable focus on AI integration, performance enhancements, and containerization. The event highlighted the introduction of App Intents as the exclusive framework for Siri interactions with third-party apps, marking the deprecation of SiriKit and emphasizing the need for developers to adapt to this change. Additionally, Apple showcased new performance profiling tools in Xcode 27 and Instruments, including the FoundationModels template for debugging AI-driven applications and enhancements in Organizer and Top Function capabilities for identifying app performance bottlenecks. The announcement of Apple's Container Machines, which enable running OCI Linux containers on macOS, was another key feature, aimed at improving the development of Linux-based server applications on Apple devices, although it currently lacks multi-container orchestration support. These developments represent Apple's strategic push to enhance app accessibility, performance, and development tools for its ecosystem.

Quick Connect is a new feature designed to optimize the use of Build Cache by identifying which workflows within continuous integration (CI) processes will benefit most significantly from caching, thereby reducing feedback loops. By analyzing the last 30 days of build data, Quick Connect offers tailored predictions of time savings, allowing users to connect high-impact workflows and skip those that won't yield significant improvements. These predictions are based on actual workflow compositions and compared against similar projects, ensuring relevance to specific user scenarios. The feature considers the diverse nature of workflows, such as those heavy on compilation versus those focused on testing, to provide accurate recommendations. The process involves establishing a baseline without caching, grouping commands into buckets like Gradle and Xcode, and classifying workflows before enabling Build Cache. Users are given a ranked list of their workflows by projected time savings, enabling informed decision-making to enhance efficiency and reduce build times. This approach leverages real usage data to offer a more precise starting point for optimization compared to traditional benchmarks.
