This package adds two new UnitSpeed types that distance runners often use for paces: .minutesPerMile and .minutesPerKilometer. It also adds multiplication and division operators for the basic "speed * time = distance" formula. Finally, it adds type aliases to make working with measurements easier and extensions to create measurements from Double values more readable.
// Basic usage
let pace = Measurement<UnitSpeed>(value: 10, unit: .minutesPerMile)
print(pace) // "10.0 min/mile"
// Usage with type aliases
let kmPace = Speed(value: 6, unit: .minutesPerKilometer)
let duration = Duration(value: 30, unit: .minutes)
let distance = Distance(value: 1600, unit: .meters)
// Usage with Double extensions
let milePace = 10.minutesPerMile
let duration = 30.5.minutes
let distance = 5.miles
// Operators
let duration = 10.miles * 6.25.minutesPerMile
let distance = 51.minutes * 5.minutesPerKilometer
let speed = (17.minutes / 5.kilometers).converted(to: .minutesPerMile)This component is designed to be used with Swift Package Manager. Add the following to your Package.swift file's dependencies:
.package(url: "https://github.com/brantonb/RunningPace.git", from: "0.1.0")And then add import RunningPace wherever needed.
Pull requests are welcome. Before submitting, please ensure that all tests pass and SwiftLint is clean.
This project uses SwiftLint via the Mint package manager. After installing Mint, run SwiftLint by executing:
$ mint run swiftlintInstall Docker and then run ./testLinuxOnDocker.sh. It will pull the latest swift image from Docker Hub, mount the current directory at /src, and then run the tests from inside the container.
