Reads the network load using sysctl / NET_RT_IFLIST2
Shows how to alloc and dealloc Swift pointers of type UnsafePointer and UnsafeMutablePointer
Includes a timer implementation using Grand Central Dispatch / DISPATCH_SOURCE_TYPE_TIMER
Does not require third-party code to compile. The only dependencies are import Cocoa and import Darwin.

Visual parameters, update intervals, and the maximum network load can be set in the file App.swift

Disclaimer

This just is a simple app to test the capabilities of Swift and not intended to be used in production environments. If you are looking for a real app that monitors your Mac, i highly recommend iStatMenus.

Please notice that i'm not affiliated in any way with Bjango, the developer of iStatMenus.
