# allDevices(matching:) Provides a snapshot of all the paired devices known to your app. ``` static func allDevices(matching: Predicate) -> WAPairedDevice.DevicesSequence ``` ## Parameters `matching` The predicate that filters the devices. The system only provides updates for devices matching this predicate. ## Return Value A new [`WAPairedDevice.DevicesSequence`](/documentation/WiFiAware/WAPairedDevice/DevicesSequence) that returns [`WAPairedDevice.Devices`](/documentation/WiFiAware/WAPairedDevice/Devices) elements holding a snapshot of the currently paired devices known to your app. ## Discussion This method gets an `AsyncSequence` that provides snapshots of all [`WAPairedDevice.Devices`](/documentation/WiFiAware/WAPairedDevice/Devices) currently paired and known to your app that match the provided predicate, and provides updates when the snapshot of [`WAPairedDevice.Devices`](/documentation/WiFiAware/WAPairedDevice/Devices) matching that predicate changes. The sequence outputs an empty dictionary if there are no paired devices matching the predicate that are known to your app, or if a person removes all of your app’s matching paired devices. You can select the set of `Devices` matching a filter from this property using the code below: ```swift let filter = #Predicate { $0.pairingInfo?.vendorName.starts(with: "Example Inc") ?? false } // Get a snapshot of all paired devices at the current moment. guard let devices = try await WAPairedDevice.allDevices(matching:filter).current() { return } // Get a snapshot of all paired devices at the current moment, and get a new snapshot each time a device is added, changed, or removed. for try await devices in WAPairedDevice.allDevices(matching:filter) { // Process update. } ``` --- Copyright © 2026 Apple Inc.
