Details

• Reads the cpu load using host_processor_info / PROCESSOR_CPU_LOAD_INFO
• 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.

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.
