I am able to show Device usage in a pie chart / custom view by using DeviceActivityReport extension. DeviceActivityReportScene, DeviceActivityResults every thing is working as expected.
I can get application identifier and names from DeviceActivityData but wondering how I can show/get the Application ICON for each app while showing its usage.
Apple in its presentation show the custom view that is showing Application icons. I have attached the screen show and also highlighted the App icon section.
