NetworkFlows

A simple SwiftPM package reporting network traffic to you.

Introduction

NetworkFlows provides you with all the information you need to display network traffic.

Include:

• Upload / Download Total (After Reboot): wifi, cellular, all
• Upload / Download per Second: wifi, cellular, all

Value and unit are in separate properties, so you can display them as you like.

Usage

With ObservedObject (SwiftUI)

1. Add the ObservedObject.

@ObservedObject var traffic = ObservableTrafficMonitor.observableShared

2. Show everything you want.

Text(traffic.newTrafficInfo?.trafficPerSecond.downTotal.humanReadableNumber ?? "--")
+
Text(" ")
+
Text(traffic.newTrafficInfo?.trafficPerSecond.downTotal.humanReadableNumberUnit ?? "--")

It should look like: 100 KB/s.

With Delegate

1. Conform to TrafficMonitorDelegate.

func trafficMonitor(updatedInfo: TrafficInfo) {
    let number = updatedInfo.trafficPerSecond.downTotal.humanReadableNumber
    let unit = updatedInfo.trafficPerSecond.downTotal.humanReadableNumberUnit
    print(number + " " + unit)
}

2. Set the delegate to self.

TrafficMonitor.shared.delegate = self

That's it! Check out the demo app for more information.
