VDDate 📆

VDDate is a Swift library that offers a robust set of extensions for the Date struct, enhancing its capabilities and making date manipulation in Swift more intuitive and powerful.

• Convenience Date.inits with components parameters year, month, day etc.
• Convenience Date.inits from string with format.
• Helper vars: iToday, isTomorrow, isYesterday, iso8601.
• var components, var for each component: day, month, year etc, mutating subscript with Calendar.Component.
• start(of: Calendar.Component) -> Date.
• end(of: Calendar.Component) -> Date.
• matches(DateComponents) -> Bool.
• isInSame(Calendar.Component) -> Bool.
• isCurrent(Calendar.Component) -> Bool
• isEqual(to: Date, toGranularity: Calendar.Component) -> Bool.
• number(of: Calendar.Component, from: Date) -> Int
• numbers(of components: Set<Calendar.Component>, from: Date) -> DateComponents
• components(_ components: Set<Calendar.Component>, from: Date) -> DateComponents
• range(of: Calendar.Component, in: Calendar.Component) -> Range<Int> - range of component, for example range(of: .day, in: .month) returns smth like 1..<32.
• interval(byAdding: DateComponents) -> DateInterval
• interval(of: Calendar.Component, in: Calendar.Component) -> DateInterval
• number(of: Calendar.Component) -> Int
• number(of: Calendar.Component, in: Calendar.Component) -> Int
• DateFormat struct with predefined format components.
• string(DateFormat) -> String Note: Deprecated since iOS 15.0 in favor of formatted(FormatStyle).
• string(date: DateFormatter.Style, time: DateFormatter.Style) -> String Note: Deprecated since iOS 15.0 in favor of formatted(FormatStyle).
• string(format: RelativeDateFormat<DateFormat>) - method for converting formatting date relative to current (or any other) date, example:

date.string(
  RelativeDateFormat(.iso8601) // default format
    .at(.day(-1), "'Yesterday'") // format for yesterday date
    .at(.day(0), "'Today'") // format for today date
    .at(.week(0), [.weekday]) // format for this week date
    .at(.year(0), "dd.MM") // format for this year date
)

Note: Deprecated since iOS 15.0 in favor of formatted(RelativeDateFormatStyle)

• formatted(RelativeDateFormatStyle)
• name(of: Calendar.Component) -> String
• ordinality(of: Calendar.Component, in: Calendar.Component) -> Int? and convenience methods for each component like day(in: Calendar.Component).
• Minus operator for date returns TimeInterval.
• adding(DateComponents) -> Date
• adding(Int, Calendar.Component) -> Date
• setting(DateComponents) -> Date
• setting(Int, Calendar.Component) -> Date
• compare(with: Date, toGranularity: Calendar.Component) -> ComparasionResult
• nextWeekend(direction: Calendar.SearchDirection) -> DateInterval?
• next(Calendar.Component, direction: Calendar.SearchDirection) -> Date
• nearest(DateComponents) -> Date?
• rounded(Calendar.Component, by: Int) -> Date date rounded by some component, useful when you deal with regular time intervals.

All methods accept a Calendar parameter and, in some cases, TimeZone or Locale.
I've introduced static variables: Calendar.default, TimeZone.default, and Locale.default.
These variables serve as the default values for each respective method. You can modify each default variable either globally or specifically for a given method.

• DatesCollection struct and function each(Int, Calendar.Component) -> DatesCollection.

• Arithmetic operators: +, - between DateComponents, +, -, /, * between DateComponents and Int, +, - between DateComponents and Date.
• Convenience static methods for each component like .day(3).
• Extensions on BinaryInteger like 2.days, so now it possible to write date + 2.days.
• DateComponents now is expressible by dictionary literal like [.day: 2, .month: 1]
• mutating subscript with Calendar.Components.
• rawValue: [Calendar.Component: Int] - dictionary with components.
