Duration

ISO 8601 duration implementation for Swift using Codable.

This micro-framework should help with handling duration written using the ISO 8601 standard. It allows parsing a string like "P3Y6M4DT12H30M5S" to TimeInterval. More about ISO 8601 standard you can read in wiki https://en.wikipedia.org/wiki/ISO_8601#Durations

Usage

Usage is very simple, you can use Duration(string: String):

import ISO8601Duration

let duration = Duration(string: "P3Y6M4DT12H30M5S")
print(duration.timeInterval) //110615405.0

Or you can decode from JSON like this:

{
  "duration": "P3Y6M4DT12H30M5S"
}

then you can create your own structure:

import ISO8601Duration

struct Box: Codable {
  let duration: Duration
}

add load data in a typical way:

let data =  Data(bytes: "{\"duration\":\"P3Y6M4DT12H30M5S\"}".utf8) //load you data
let decoder = JSONDecoder()
let box = try decoder.decode(Box.self, from: data)
print(box.duration.timeInterval) //110615405.0

Installation

Use the CocoaPods.

Add to your Podfile

pod 'ISO8601Duration'

and then call

pod install

and import

import ISO8601Duration
