What is SwiftTimeSpecification?

SwiftTimeSpecification is an implementation of struct timespec (struct mach_timespec on OS X) in Swift.
Its prototype is YOCKOW’s Gist.

Sample Code

Measure

import TimeSpecification

let duration = TimeSpecification.measure(repeatCount: 100) { doIt() }
print("It took \(duration) seconds.") // -> Processing time to execute `doIt` 100 times. 

With Date

import TimeSpecification

let now = TimeSpecification(clock: .calendar)
let dateNow = Date(timeIntervalSince1970: now) // -> Almost same with Date(timeIntervalSince1970: Double(time(nil)))

Requirements

• Swift 5 (including compatibility mode for 4, 4.2)
