## What’s Changed

Workarounds unit test execution hanging intermittently due to xcodebuild’s built-in diagnostics collection.  
Since Xcode 26, xcodebuild collects a simulator sysdiagnose of its own after a failing test run. This is similar to what the Step collected on its own.

The Input **Collect Simulator diagnostics** (`collect_simulator_diagnostics`) set to `never` now disables xcodebuild’s diagnostic too.  
To enable Simulator diagnostics collection, use:

- `on_failure` to override any project settings, or
- `project_setting` to preserve test plan settings (the default is collection on failure).

Our collection is disabled for favor of xcodebuild’s built-in, when avaialble. (The underlying command is a similar `simctl diagnose`)
