# DeviceActivityFilter A type that filters the device activity data to include in a report. ``` struct DeviceActivityFilter ``` ## Overview Your app can choose to filter device activity data for a specific date interval, filter by user and device, as well as specify a subset of applications, categories, and web domains to include in a report. ## Topics ### Structures [`struct Devices`](/documentation/DeviceActivity/DeviceActivityFilter/Devices-swift.struct) A type your app uses to indiciate which devices to include in a device activity report. [`struct Users`](/documentation/DeviceActivity/DeviceActivityFilter/Users-swift.struct) A type your app uses to indicate which users to include in a device activity report. ### Initializers [`init(segment: DeviceActivityFilter.SegmentInterval, devices: DeviceActivityFilter.Devices?, applications: Set, categories: Set, webDomains: Set)`](/documentation/DeviceActivity/DeviceActivityFilter/init(segment:devices:applications:categories:webDomains:)) Creates a new filter for the current user. [`init(segment: DeviceActivityFilter.SegmentInterval, users: DeviceActivityFilter.Users, devices: DeviceActivityFilter.Devices, applications: Set, categories: Set, webDomains: Set)`](/documentation/DeviceActivity/DeviceActivityFilter/init(segment:users:devices:applications:categories:webDomains:)) Creates a new filter for the specified users and devices. ### Instance Properties [`var applications: Set`](/documentation/DeviceActivity/DeviceActivityFilter/applications) An optional set of applications to include in a report. [`var categories: Set`](/documentation/DeviceActivity/DeviceActivityFilter/categories) An optional set of categories to include in a report. [`let devices: DeviceActivityFilter.Devices?`](/documentation/DeviceActivity/DeviceActivityFilter/devices-swift.property) The devices to include in a report. [`var segmentInterval: DeviceActivityFilter.SegmentInterval`](/documentation/DeviceActivity/DeviceActivityFilter/segmentInterval-swift.property) The interval at which the system subdivides the report’s device activity data during a specified date interval. [`let users: DeviceActivityFilter.Users?`](/documentation/DeviceActivity/DeviceActivityFilter/users-swift.property) The users to include in a report. [`var webDomains: Set`](/documentation/DeviceActivity/DeviceActivityFilter/webDomains) An optional set of web domains to include in a report. ### Enumerations [`enum SegmentInterval`](/documentation/DeviceActivity/DeviceActivityFilter/SegmentInterval-swift.enum) A type indicating the interval at which the system subdivides device activity data within a specified date interval. ## Relationships ### Conforms To [`Equatable`](/documentation/Swift/Equatable) --- Copyright © 2026 Apple Inc.
