ISO8601PeriodDuration

Usage

Lightweight library to parse ISO 8601 period-duration strings into DateComponents, motivated by the lack of support for this standard in Foundation.

It's a rough equivalent of Java's PeriodDuration, except it only provides the parsing side of its functionality, leaving representation to the built-in DateComponents.

It leverages Swift 5.1's property wrappers in order to make parsing functionality as unintrusive as possible, optimistic for a seamless drop-in replacement when/if Apple ever introduces a similar solution into Foundation.

Example

Consider the following struct:

struct Appointment: Decodable {
    @ISO8601PeriodDuration var duration: DateComponents
}

Decoded with the following JSON:

{
    "duration": "PT2H30M"
}

It'll yield:

DateComponents
    .year -> nil
    .month -> nil
    .day -> nil
    .hour -> 2
    .minute -> 30
    .second -> nil

Note: weeks (P3W) are supported, though they end up translated to days.
