Use the Metrics organizer to view metrics reports for apps that you distribute through the App Store.
Important: For apps released in the App Store, collecting metrics data requires that the user agree to share user crash and energy data with developers.
To view metrics reports, choose Window > Organizer and click Metrics. Xcode refreshes the data in the metrics reports daily. Note that there is a delay between when you first distribute a version of your app and when metrics data is available for that version.
Use the first column to select an app and the second column to select a category of metric reports. In the detail area, view the metrics report. If the Metrics organizer is empty, go to If no crash, energy, or metrics reports appear in the organizer and review Supported metric reports. The time the metrics were last updated is shown at the upper-left of the detail area.
Use the device selection drop down to view data for one model of iPhone or iPad, all iPhone models, or all iPad models. Use the displayed data subset drop down to show the typical (50th percentile) data or to show the data with the highest impact (90th percentile.)
