WWDC26: Create robust evaluations for agentic apps | Apple
Apple's new Evaluations framework in Xcode 27 lets Swift developers test and scale agentic AI app quality.
“The quality of your evaluation results is only as good as the data behind them.”
At WWDC26 Apple detailed its Evaluations framework (new in Xcode 27 across iOS, macOS, watchOS, visionOS) for assessing intelligence-powered Swift app features, including synthetic data generation and evaluating tool-calling agentic workflows. It signals Apple's push to give developers production-grade tooling for on-device AI quality, but as a technical tutorial it is a niche developer-ecosystem signal rather than a market-moving announcement.
