Documentation for the new Metal Performance HUD in macOS/iOS/iPadOS/tvOS 26 is now available – covering in great detail HUD customization, available metrics, performance insights, and performance reports: (5 articles in total).

In Xcode 26, the Dependency Viewer in Metal Debugger has been updated to visualize fine-grain per-stage dependencies.

The Metal Performance HUD has been updated with new metrics and a customizable user interface. It also now has the ability to identify performance insights and generate performance reports. Learn more at

Metal Debugger in Xcode 26 comes with brand new debugging support for Machine Learning in Metal 4. Use the new Machine Learning network debugger to inspect and debug your ML network, including inspecting intermediate tensor data. Learn more at

Metal 4 comes with a streamlined API for optimal performance. Compilation is explicit and faster. And comes with first-class support for ML. Execute full models in your command buffers or inline inference operations alongside your shader code.
