Date

A specific point in time, independent of any calendar or time zone.

A Date value encapsulate a single point in time, independent of any particular calendrical system or time zone. Date values represent a time interval relative to an absolute reference date.

The Date structure provides methods for comparing dates, calculating the time interval between two dates, and creating a new date from a time interval relative to another date.

We can use date values in conjunction with DateFormatter instances to create localized representations of dates and times and with Calendar instances to perform calendar arithmetic.

Date bridges to the NSDate class. You can use these interchangeably in code that interacts with Objective-C APIs.

DateFormatter

It's a formatter that converts between dates and their textual representations.

Instances of DateFormatter create string representations of NSDate objects, and convert textual representations of dates and times into NSDate objects.

For user-visible representations of dates and times, DateFormatter provides a variety of localized presets and configuration options.

For fixed format representations of dates and times, you can specify a custom format string.

Note:

When working with date representations in ISO 8601 format, use ISO8601DateFormatter instead.

To represent an interval between two NSDate objects, use DateIntervalFormatter instead.

To represent a quantity of time specified by an NSDateComponents object, use DateComponentsFormatter instead.
