From simple date manipulation to complex business logic SwiftDate maybe the right choice for your next project.

Let me show to you the main features of the library:

1. Date Parsing

SwiftDate can recognize all the major datetime formats automatically (ISO8601, RSS, Alt RSS, .NET, SQL, HTTP...) and you can also provide your own formats. Creating a new date has never been so easy!

// All default datetime formats (15+) are recognized automatically
let _ = "2010-05-20 15:30:00".toDate()
// You can also provide your own format!
let _ = "2010-05-20 15:30".toDate("yyyy-MM-dd HH:mm")
// All ISO8601 variants are supported too with timezone parsing!
let _ = "2017-09-17T11:59:29+02:00".toISODate()
// RSS, Extended, HTTP, SQL, .NET and all the major variants are supported!
let _ = "19 Nov 2015 22:20:40 +0100".toRSS(alt: true)

2. Date Manipulation

Date can be manipulated by adding or removing time components using a natural language; time unit extraction is also easy and includes the support for timezone, calendar and locales!

Manipulation can be done with standard math operators and between dates, time intervals, date components and relevant time units!

// Math operations support time units
let _ = ("2010-05-20 15:30:00".toDate() + 3.months - 2.days)
let _ = Date() + 3.hours
let _ = date1 + [.year:1, .month:2, .hour:5]
let _ = date1 + date2
// extract single time unit components from date manipulation
let over1Year = (date3 - date2).year > 1

3. Date Comparison

SwiftDate include an extensive set of comparison functions; you can compare two dates by granularity, check if a date is an particular day, range and practically any other comparison you ever need.

Comparison is also available via standard math operators like (>, >=, <, <=).

// Standard math comparison is allowed
let _ = dateA >= dateB || dateC < dateB

// Complex comparisons includes granularity support
let _ = dateA.compare(toDate: dateB, granularity: .hour) == .orderedSame
let _ = dateA.isAfterDate(dateB, orEqual: true, granularity: .month) // > until month granularity
let _ = dateC.isInRange(date: dateA, and: dateB, orEqual: true, granularity: .day) // > until day granularity
let _ = dateA.earlierDate(dateB) // earlier date
let _ = dateA.laterDate(dateB) // later date

// Check if date is close to another with a given precision
let _ = dateA.compareCloseTo(dateB, precision: 1.hours.timeInterval

// Compare for relevant events:
// .isToday, .isYesterday, .isTomorrow, .isWeekend, isNextWeek
// .isSameDay, .isMorning, .isWeekday ...
let _ = date.compare(.isToday)
let _ = date.compare(.isNight)
let _ = date.compare(.isNextWeek)
let _ = date.compare(.isThisMonth)
let _ = date.compare(.startOfWeek)
let _ = date.compare(.isNextYear)
// ...and MORE THAN 30 OTHER COMPARISONS BUILT IN

// Operation in arrays (oldestIn, newestIn, sortedByNewest, sortedByOldest...)
let _ = DateInRegion.oldestIn(list: datesArray)
let _ = DateInRegion.sortedByNewest(list: datesArray)

4. Date Creation with Region (Timezone, Calendar & Locale)

You can create new dates from a string, time intervals or using date components. SwiftDate offers a wide set of functions to create and derivate your dates even with random generation!

// All dates includes timezone, calendar and locales!
// Create from string
let rome = Region(calendar: Calendars.gregorian, zone: Zones.europeRome, locale: Locales.italian)
let date1 = DateInRegion("2010-01-01 00:00:00", region: rome)!

// Create date from intervals
let _ = DateInRegion(seconds: 39940, region: rome)
let _ = DateInRegion(milliseconds: 5000, region: rome)

// Date from components
let _ = DateInRegion(components: {
	$0.year = 2001
	$0.month = 9
	$0.day = 11
	$0.hour = 12
	$0.minute = 0
}, region: rome)
let _ = DateInRegion(year: 2001, month: 1, day: 5, hour: 23, minute: 30, second: 0, region: rome)

// Random date generation with/without bounds
let _ = DateInRegion.randomDate(region: rome)
let _ = DateInRegion.randomDate(withinDaysBeforeToday: 5)
let _ = DateInRegion.randomDates(count: 50, between: lowerLimitDate, and: upperLimitDate, region: rome)

5. Derivated Dates

Date can be also generated starting from other dates; SwiftDate includes an extensive set of functions to generate. Over 20 different derivated dates can be created easily using dateAt() function.

let _ = DateInRegion().dateAt(.endOfDay) // today at the end of the day
// Over 20 different relevant dates including .startOfDay,
// .endOfDay, .startOfWeek, .tomorrow, .nextWeekday, .nextMonth, .prevYear, .nearestMinute and many others!
let _ = dateA.nextWeekday(.friday) // the next friday after dateA
let _ = (date.dateAt(.startOfMonth) - 3.days)
let _ = dateA.compare(.endOfWeek)

// Enumerate dates in range by providing your own custom
// increment expressed in date components
let from = DateInRegion("2015-01-01 10:00:00", region: rome)!
let to = DateInRegion("2015-01-02 03:00:00", region: rome)!
let increment2 = DateComponents.create {
	$0.hour = 1
	$0.minute = 30
	$0.second = 10
}
// generate dates in range by incrementing +1h,30m,10s each new date
let dates = DateInRegion.enumerateDates(from: fromDate2, to: toDate2, increment: increment2)

// Get all mondays in Jan 2019
let mondaysInJan2019 = Date.datesForWeekday(.monday, inMonth: 1, ofYear: 2019)

// Altering time components
let _ = dateA.dateBySet(hour: 10, min: 0, secs: 0)

// Truncating a date
let _ = dateA.dateTruncated(at: [.year,.month,.day]) // reset all time components keeping only date

// Rounding a date
let _ = dateA.dateRoundedAt(.toMins(10))
let _ = dateA.dateRoundedAt(.toFloor30Mins)

// Adding components
let _ = dateA.dateByAdding(5,.year)

// Date at the start/end of any time component
let _ = dateA.dateAtEndOf(.year) // 31 of Dec at 23:59:59
let _ = dateA.dateAtStartOf(.day) // at 00:00:00 of the same day
let _ = dateA.dateAtStartOf(.month) // at 00:00:00 of the first day of the month

6. Components Extraction

You can extract components directly from dates and it includes the right value expressed in date's region (the right timezone and set locale!).

// Create a date in a region, London but with the lcoale set to IT
let london = Region(calendar: .gregorian, zone: .europeLondon, locale: .italian)
let date = DateInRegion("2018-02-05 23:14:45", format: dateFormat, region: london)!

// You can extract any of the all available time units.
// VALUES ARE EXPRESSED IN THE REGION OF THE DATE (THE RIGHT TIMEZONE).
// (you can still get the UTC/absolute value by getting the inner's absoluteDate).

let _ = date.year // 2018
let _ = date.month // 2
let _ = date.monthNameDefault // 'Febbraio' as the locale is the to IT!
let _ = date.firstDayOfWeek // 5
let _ = date.weekdayNameShort // 'Lun' as locale is the to IT
// ... all components are supported: .year, .month, .day, .hour, .minute, .second,
// .monthName, .weekday, .nearestHour, .firstDayOfWeek. .quarter and so on...

7. Switch between timezones/locale and calendars

You can easily convert any date to another region (aka another calendar, locale or timezone) easily! New date contains all values expressed into the destination reason

// Conversion between timezones is easy using convertTo(region:) function
let rNY = Region(calendar: Calendars.gregorian, zone: Zones.americaNewYork, locale: Locales.english)
let rRome = Region(calendar: Calendars.gregorian, zone: Zones.europeRome, locale: Locales.italian)
let dateInNY = "2017-01-01 00:00:00".toDate(region: rNY)
let dateInRome = dateInNY?.convertTo(region: rRome)!
print(dateInRome.toString()) // "dom gen 01 06:00:00 +0100 2017\n"

// You can also convert single region's attributes
let dateInIndia = dateInNY?.convertTo(timezone: Zones.indianChristmas, locale: Locales.nepaliIndia)
print("\(dateInIndia!.toString())") // "आइत जनवरी ०१ १२:००:०० +0700 २०१७\n"

8. Date Formatting

Date formatting is easy, you can specify your own format, locale or use any of the provided ones.

// Date Formatting
let london = Region(calendar: .gregorian, zone: .europeLondon, locale: .english)
let date = ... // 2017-07-22T18:27:02+02:00 in london region
let _ = date.toDotNET() // /Date(1500740822000+0200)/
let _ = date.toISODate() // 2017-07-22T18:27:02+02:00
let _ = date.toFormat("dd MMM yyyy 'at' HH:mm") // "22 July 2017 at 18:27"

// You can also easily change locale when formatting a region
let _ = date.toFormat("dd MMM", locale: .italian) // "22 Luglio"

// Time Interval Formatting as Countdown
let interval: TimeInterval = (2.hours.timeInterval) + (34.minutes.timeInterval) + (5.seconds.timeInterval)
let _ = interval.toClock() // "2:34:05"

// Time Interval Formatting by Components
let _ = interval.toString {
	$0.maximumUnitCount = 4
	$0.allowedUnits = [.day, .hour, .minute]
	$0.collapsesLargestUnit = true
	$0.unitsStyle = .abbreviated
} // "2h 34m"

9. Relative Date Formatting (fully customizable!)

Relative formatting is all new in SwiftDate; it supports 120+ languages with two different styles (.default, .twitter), 9 flavours (.long, .longTime, .longConvenient, .short, .shortTime, .shortConvenient, .narrow, .tiny, .quantify) and all of them are customizable as you need. The extensible format allows you to provide your own translations and rules to override the default behaviour.

// Twitter Style
let _ = (Date() - 3.minutes).toRelative(style: RelativeFormatter.twitterStyle(), locale: Locales.english) // "3m"
let _ = (Date() - 6.minutes).toRelative(style: RelativeFormatter.twitterStyle(), locale: Locales.italian) // "6 min fa"

// Default Style
let _ = (now2 - 5.hours).toRelative(style: RelativeFormatter.defaultStyle(), locale: Locales.english) // "5 hours ago"
let y = (now2 - 40.minutes).toRelative(style: RelativeFormatter.defaultStyle(), locale: Locales.italian) // "45 minuti fa"

10. Codable Support

Both DateInRegion and Region fully support the new Swift's Codable protocol. This mean you can safely encode/decode them:

// Encoding/Decoding a Region
let region = Region(calendar: Calendars.gregorian, zone: Zones.europeOslo, locale: Locales.english)
let encodedJSON = try JSONEncoder().encode(region)
let decodedRegion = try JSONDecoder().decode(Region.self, from: encodedJSON)

// Encoding/Decoding a DateInRegion
let date = DateInRegion("2015-09-24T13:20:55", region: region)
let encodedDate = try JSONEncoder().encode(date)
let decodedDate = try JSONDecoder().decode(DateInRegion.self, from: encodedDate)

11. Time Periods

SwiftDate integrates the great Matthew York's DateTools module in order to support Time Periods.

See Time Periods section of the documentation.

Upgrading from Swift 4.x

SwiftDate 5.x is a complete rewrite of the library. While it introduces several new features a great part of the work is about a consistent naming of the functions: some was renamed while deprecated ones was removed.

If you miss a features or you are interested in a new one create a new Issue.

Important Note about Default Region

In SwiftDate 4.x the default region is automatically set to local regiomn, where all attributes are set automatically to the current's device's locale, timezone and calendar.

Since SwiftDate 5, in order to be more comply with Date's default behaviour, the default region's timezone is set to GMT+0 (UTC).

If you want to restore the old behaviour just set it to Region.local just after the launch of the app.

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
	SwiftDate.defaultRegion = Region.local // set region to local device attributes
	// ... do something else
	return true
}

Added/Removed/Replaced Methods

  • Date.defaultRegion was renamed to SwiftDate.defaultRegion and you can both read and set it.
  • Date.setDefaultRegion(:) was removed; use SwiftDate.defaultRegion's setter.
  • TimeZoneName is now Zones and its conform to the new ZonesConvertible protocol. All parameters (like Region inits function) takes now a generic ZonesConvertible instance: this mean you can pass one of the enum values of the zone or just an instance of TimeZone object (or you can conform your own class to it).
  • CalendarName is now Calendars and its conform to the new CalendarConvertible protocol. All parameters (like Region inits function) takes now a generic CalendarConvertible instance: this mean you can pass one of the enum values of the zone or just an instance of Calendar object (or you can conform your own class to it).
  • LocaleName is now Locales and its conform to the new LocaleConvertible protocol. All parameters (like Region inits function) takes now a generic LocaleConvertible instance: this mean you can pass one of the enum values of the zone or just an instance of Calendar object (or you can conform your own class to it).
  • Date/DateInRegion: isBetween() function was renamed isInRange()
  • Date/DateInRegion: isAfter() was renamed to isAfterDate()
  • Date/DateInRegion: isBefore() was renamed to isBeforeDate()
  • String extension methods date(format:fromRegion) and date(formats:fromRegion) are now replaced by toDate(_:region) (while similar shortcuts methods are added to parse common formats: toISODate(), toDotNETDate(), toRSSDate() and toSQLDate().
  • Removed Int extension second,minute,hour,day,week,month,year due to inconsistence (use plurar versions seconds,minutes etc.
  • Related dates generation is now grouped under the dateAt() function as enum list. Therefore nextWeekend, `previo
  • DateInRegion: roundedAt() is now replaced by dateRoundedAt() which now compacts paramters in a single enum.
  • DateInRegion: startOf() and endOf() are now replaced by dateAtStartOf() and dateAtEndOf()and include support for both single and multiple units.
  • DateInRegion: atTime() is now replaced by dateBySet(hour:min:secs:options)
  • DateInRegion: DateInRegion's static distantFuture() and distantPast are now future() and past()
  • DateInRegion:next(day:) is now part of the dateAt() function with enum .weekday(_).
  • DateInRegion: add(components:) is now replaced by dateByAdding(_:_:)
  • DateInRegion: at(unit:value:) and at(values:keep:) are now replaced by dateBySet().
  • nextDSTTransitionDate property is now part of the enum of dateAt()
  • recentDate() and oldestDate() are now called newestIn() and oldestIn()
  • TimeInterval Extension: in(_:toDate:of:) is now replaced by toUnits(_:from:)
  • TimeInterval Extension: string() is now replaced by toString()
  • DateTimeInterval class is now replaced by TimePeriod class and its descendants
  • DateInRegion: dates(between:and:increment:) to enumerate dates is now replaced by enumerateDates(from:to:increment:)
  • DateInRegion: colloquial formatter colloquial(toDate:options:) is now replaced by toRelative(since:style:locale:)
  • Formatting method iso8601() is now toISO8601() and other methods to..() was added to simplify formatting task.
  • Date/DateInRegion: Introduced compareCloseTo() to compare two dates against a precision value.
  • Added several shortcut methods as extensions of String to parse dates: toISODate(), toDotNETDate(), toRSSDate() and toSQLDate().
  • Comparison methods are now grouped by compare() function and a list of all available enums.

CHANGELOG

  • #495 Added Thai language (thanks to Thanakrit Weekhamchai)
  • #492 Introduced a new ColloquialDateFormatter class

  • #414 Added Daylight Saving Time functions: .isDST in DateInRegion (it returns true if the date uses daylight saving time); .DSTOffset in DateInRegion (it returns the value (in seconds) of the daylight saving time offset of the represented date), . nextDSTTransitionDate in DateInRegion (it returns the next daylight saving time transition after currently represented date when expressed); nextDSTTransitionDate() func in Date (it returns the next dst transition date when receiver is expressed in a particular timezone); DSTOffset() func in Date (it returns the offset of daylight saving time when receiver is expressed in a particular timezone); isDST() func in Date (it returns if receiver date uses daylight saving time when expressed in a particular timezone).

Fixes

  • #410 Several fixes while parsing less common ISO8601 formats (weeks only w/wo implicit year/month/day).
  • #411 Parsing an ISO8601 string now results in a DateInRegion which contains the correct timezone defined (Date instances are now converted automatically to be time-independent).
  • #412 Updated Unit Tests to become compatible with the new APIs changes. All tests now passes.
  • #409 Fixed an issue converting a difference between two dates when its more than 24 hours, but less than 48 hours (incorrectly the colloquial values returns 'yesterday')
