Turbine a conectividade do dispositivo com o Wi-Fi Aware

6:57 - Access capabilities and services

import WiFiAware

// Check if Wi-Fi Aware is supported on your device
guard WACapabilities.supportedFeatures.contains(.wifiAware) else { return }

// Publishable service declared in Info.plist
extension WAPublishableService {
    public static var fileService: WAPublishableService {
        allServices["_file-service._tcp"]!
    }
}

// Subscribable services declared in Info.plist
extension WASubscribableService {
    public static var fileService: WASubscribableService {
        allServices["_file-service._tcp"]!
    }
    public static var droneService: WASubscribableService {
        allServices["_drone-service._udp"]!
    }
}

10:33 - Pair with DeviceDiscoveryUI

import DeviceDiscoveryUI
import WiFiAware
import SwiftUI

// Listener (Publisher) Device
// Invoke Listener UI
DevicePairingView(.wifiAware(.connecting(to: .fileService, from: .selected([])))) {
    // Provide a view to display to user before launching System UI
} fallback: {
    // Provide a view in case of error
}

// Browser (Subscriber) Device
// Invoke Browser UI
DevicePicker(.wifiAware(.connecting(to: .selected([]), from: .fileService))) { endpoint in
    // Process the paired network endpoint
} label: {
    // Provide a view to display to user before launching System UI
} fallback: {
    // Provide a view in case of error
}

12:29 - Pair with AccessorySetupKit

import AccessorySetupKit

// Configure ASDiscoveryDescriptor (Subscriber)
let descriptor = ASDiscoveryDescriptor()
descriptor.wifiAwareServiceName = "_drone-service._udp"
descriptor.wifiAwareModelNameMatch = .init(string: "Example Model")
descriptor.wifiAwareVendorNameMatch = .init(string: "Example Inc", compareOptions: .literal)
let item = ASPickerDisplayItem(name: "My Drone",
                               productImage: UIImage(named: "DroneProductImage")!,
                               descriptor: descriptor)

// Create and activate session
let session = ASAccessorySession()
session.activate(on: sessionQueue) { event in
    // Closure will execute when device is added with event: .accessoryAdded
    // ASAccessoryWiFiAwarePairedDeviceID can be used to lookup a WAPairedDevice
}
// Present Picker UI
session.showPicker(for: [item]) { error in
    // Handle error
}

13:51 - Access paired devices

import Foundation
import WiFiAware

// WAPairedDevice
var device: WAPairedDevice // Get using WAPairedDevice.allDevices

// Access WAPairedDevice properties
let pairingName = device.pairingInfo?.pairingName
let vendorName = device.pairingInfo?.vendorName
let modelName = device.pairingInfo?.modelName

// Create a filter to select devices of interest
let filter = #Predicate<WAPairedDevice> {
    $0.pairingInfo?.vendorName.starts(with: "Example Inc") ?? false
}

// Get all paired devices, matching the filter, at the current moment
// A new snapshot of all paired devices each time a device is added, changed, or removed
for try await devices in WAPairedDevice.allDevices(matching: filter) {
    // Process new snapshot of all paired devices
}

16:23 - Filter paired devices

import Foundation
import WiFiAware

// Listener (Publisher) Device
// Specify the paired devices of interest for the use case
let deviceFilter = #Predicate<WAPairedDevice> {
    $0.name?.starts(with: "My Device") ?? false
}

// Browser (Subscriber) Device
// Specify the paired devices of interest for the use case
let deviceFilter = #Predicate<WAPairedDevice> {
    $0.pairingInfo?.vendorName.starts(with: "Example Inc") ?? false
}

16:54 - Create listener and browser

import WiFiAware
import Network

// Listener (Publisher) Device: Construct a NetworkListener
let listener = try NetworkListener(for:
        .wifiAware(.connecting(to: .fileService, from: .matching(deviceFilter))),
    using: .parameters {
        TLS()
    })
    .onStateUpdate { listener, state in
        // Process state update
    }

// Browser (Subscriber) Device: Construct a NetworkBrowser
let browser = NetworkBrowser(for:
        .wifiAware(.connecting(to: .matching(deviceFilter), from: .fileService))
    )
    .onStateUpdate { browser, state in
        // Process state update
    }

17:44 - Establish a connection

// Listener (Publisher) Device: Start NetworkListener
try await listener.run { connection in  // Radio resources in use
    // Closure executes for each incoming connection
    connection.onStateUpdate { connection, state in
        // Process state update
    }
}

// Browser (Subscriber) Device: Start NetworkBrowser
let endpoint = try await browser.run { waEndpoints in // Radio resources in use
        // Review endpoints, decide whether to return or skip
        if let endpoint = self.endpoint(in: waEndpoints) { return .finish(endpoint) }
        else { return .continue }
    }
// Create the connection
let connection = NetworkConnection(to: endpoint, using: .parameters {
        TLS()
    })
    .onStateUpdate { connection, state in
        // Process state update
    }

21:11 - Tune performance

// Listener (Publisher) Device
// Configure .realtime + .interactiveVideo on NetworkListener
let listener = try NetworkListener(for:
        .wifiAware(.connecting(to: .fileService, from: .matching(deviceFilter))),
    using: .parameters {
        TLS()
    }
    .wifiAware { $0.performanceMode = .realtime }
    .serviceClass(.interactiveVideo))

// Browser (Subscriber) Device
// Configure .realtime + .interactiveVideo on NetworkConnection
let connection = NetworkConnection(to: endpoint, using: .parameters {
        TLS()
    }
    .wifiAware { $0.performanceMode = .realtime }
    .serviceClass(.interactiveVideo))

// Listener (Publisher) Device & Browser (Subscriber) Device
// Read performance report
let performanceReport = try await connection.currentPath?.wifiAware?.performance
