Nanoseconds

Simple high resolution time stamps for swift developers, along with helpful tools to work with them.

Key Features

  • High resolution time stamp
  • Built-in operators overloads
  • Useful extensions for unit conversion
  • Covert time intervals to a human readable strings
  • Linux compatible

Install

Install via the Swift Package Manger by declaring Nanoseconds as a dependency in your Package.swift:

.package(url: "https://github.com/dominicegginton/Nanoseconds", from: "1.0.0")

Remember to add Nanoseconds to your target as a dependency.

Getting Started

import Foundation
import Nanoseconds

let start = Now()
sleep(1)
let end = Now()
let duration = end - start
print(duration)  //=> 1004222113.0
