Along with the Developer Data API, Google is releasing a associated MCP server to allow growth groups to attach it to their IDEs and AI coding assistants. The corporate defined this may allow extra superior capabilities as builders are writing code, corresponding to with the ability to ask the easiest way to implement push notifications in Firebase, verify the docs to search out the easiest way to repair a particular error, or examine two completely different providers for a specific use case.

Xcode 26.3 provides agentic coding assist

Apple is enabling agentic coding inside Xcode within the newest model of the event platform (model 26.3).

Builders will now be capable of use Anthropic’s Claude Agent and OpenAI’s Codex immediately in Xcode.

“With seamless entry to Claude Agent and Codex, builders can convey the superior reasoning of those fashions immediately into their app-building workflow. This connection combines the facility of those brokers with Xcode’s native capabilities to offer the perfect outcomes when creating for Apple platforms, giving builders the flexibleness to work with the mannequin that most closely fits their venture,” Apple wrote in an announcement.

Opsera introduces new DevOps brokers to handle AI-assisted coding points

Opsera is releasing a number of new brokers as part of its Agentic DevOps providing that proactively handle DevOps workflows in an try to handle a few of the bottlenecks launched by AI-assisted coding.

Based on a latest report from the corporate, AI-assisted coding can velocity up metrics like Time-to-Pull Request or take a look at move fee, however it’s also topic to bottlenecks that sluggish supply down, corresponding to longer PR overview instances. For instance, the corporate discovered that AI-assisted workflows had a 48-58% quicker common Time-to-Pull Request, however that AI-generated pull requests wait 4.6x as lengthy to be reviewed in comparison with human-written ones.

Opera additionally discovered that AI-generated code suffered from points like elevated code duplication (13.5% vs 10.5%) and safety vulnerabilities (15-18% extra) in comparison with human-written code.
