NaiveDate
<p align="left"> <img src="https://img.shields.io/cocoapods/p/NaiveDate.svg?style=flat)"> </p>The standard Date
type is excellent for working with timestamps and time zones (e.g. 2024-09-29T15:00:00+0300
), but there are scenarios where you don't know or care about the time zone. These types of dates are often referred to as naive.
Usage
The NaiveDate
library implements three types:
NaiveDate
(e.g.2024-09-29
)NaiveTime
(e.g.15:30:00
)NaiveDateTime
(e.g.2024-09-29T15:30:00
- no time zone and no offset).
They all implement Equatable
, Comparable
, LosslessStringConvertible
, and Codable
protocols. Naive date types can also be converted to Date
, and DateComponents
.
Create
Naive dates and times can be created from a string (using a predefined format – RFC 3339, using Decodable
, or with a memberwise initializer:
NaiveDate("2024-10-01")
NaiveDate(year: 2024, month: 10, day: 1)
NaiveTime("15:30:00")
NaiveTime(hour: 15, minute: 30, second: 0)
NaiveDateTime("2024-10-01T15:30")
NaiveDateTime(
date: NaiveDate(year: 2024, month: 10, day: 1),
time: NaiveTime(hour: 15, minute: 30, second: 0)
)
Format
NaiveDate
supports Foundation.FormatStyle
:
let dateTime = NaiveDateTime("2024-11-01T15:30:00")!
dateTime.formatted(date: .numeric, time: .standard)
// prints "11/1/2024, 3:30:00 PM"
In addition to the format style, you can use built-in NaiveDateFormatter
directly.
let date = NaiveDate("2024-11-01")!
NaiveDateFormatter(dateStyle: .short).string(from: date)
// prints "Nov 1, 2024"
let time = NaiveTime("15:00")!
NaiveDateFormatter(timeStyle: .short).string(from: time)
// prints "3:00 PM"
let dateTime = NaiveDateTime("2024-11-01T15:30:00")!
NaiveDateFormatter(dateStyle: .short, timeStyle: .short).string(from: dateTime)
// prints "Nov 1, 2024 at 3:30 PM"
Convert
When you do need to work with time zones, simply convert NaiveDate
to Date
:
let date = NaiveDate(year: 2024, month: 10, day: 1)
// Creates `Date` in a calendar's time zone
// "2024-10-01T00:00:00+0300" if user is in MSK
Calendar.current.date(from: date)
let dateTime = NaiveDateTime(
date: NaiveDate(year: 2024, month: 10, day: 1),
time: NaiveTime(hour: 15, minute: 30, second: 0)
)
// Creates `Date` in a calendar's time zone
// "2024-10-01T15:30:00+0300" if user is in MSK
Calendar.current.date(from: dateTime)
Important! The naive types are called this way because they don’t have a time zone associated with them. This means the date may not actually exist in some areas in the world, even though they are “valid”. For example, when daylight saving changes are applied the clock typically moves forward or backward by one hour. This means certain dates never occur or may occur more than once. If you need to do any precise manipulations with time, always use native Date
and Calendar
.
