"Simulate MetricKit Payloads" missing from Debug menu in Xcode 27.0 beta 3

The MetricKit documentation ("Track performance by app state using MetricKit") states:

"MetricKit delivers reports on a system-determined schedule. To generate reports during development, choose Debug > Simulate MetricKit Payloads in Xcode."

https://developer.apple.com/documentation/metrickit/track-performance-by-app-state-using-metrickit

This menu item was present in Xcode 26.6, but is no longer shown under the Debug menu in Xcode 27.0 beta 3.

Steps to reproduce:

  1. Open a project in Xcode 27.0 beta 3
  2. Open the Debug menu
  3. "Simulate MetricKit Payloads" is not listed

Expected: The menu item should be available as documented, and as it was in Xcode 26.6.

Has anyone else run into this, or found a workaround for triggering MetricKit payloads in Xcode 27 betas? Filed as FB23760649.

Environment: Xcode 27.0 beta 3, macOS 26.5.2

Hi there, thanks for filing the feedback! An app needs to link to MetricKit and be running in Xcode for the payload simulation button to show up. These requirements for payload simulation to work have not changed -- only UI. Does your use case satisfy these conditions? Please update your Feedback if this doesn't work as intended.

Thanks for confirming this. I tested it myself and can confirm the menu item does appear once MetricKit is linked and the app is running via Xcode on a physical device — as described above.

However, I noticed the actual menu path differs from what's documented: it's located at Debug > MetricKit > Simulate MetricKit Payloads, not Debug > Simulate MetricKit Payloads as the documentation states.

I've filed feedback for this documentation discrepancy: FB23896803.
