Hi folks!
[i|mac|tv|vision|watch]OS 26.3 is out in the wild, and we’re now waiting for the final Xcode 26.3 release—with its new agentic coding powers. Safari 26.3 also gained support for Zstandard, a fast, lossless compression algorithm designed for real-time scenarios with impressive compression ratios.
Along with the positive news on the releases, there was an update that may have been overlooked. Apple is reportedly pushing back Gemini-powered Siri features beyond iOS 26.4 - yet another setback in their effort to deliver truly competitive capabilities to Siri.

Tools
XcodeBuildMCP
Dubbed “A Model Context Protocol (MCP) server and CLI that provides tools for agent use when working on iOS and macOS projects” XcodeBuildMCP is a pretty well-documented open-source MCP server that you can now use along with the one that Apple ships with Xcode 26.3.
Recently, it was promoted to version 2 and now ships with tons of updates (a new CLI, LLDB debugging, MCP tool annotations, Xcode integration and interoperability, config file support for project-level fine-tuning, and more). Definitely worth a look!
That’s it for Issue 79 — see you next week!
