startOfDay(for:)
Returns the first moment of a given date as a date instance.
Declaration
func startOfDay(for date: Date) -> DateParameters
- date:
The date for which to perform the calculation.
Return Value
An NSDate instance representing the first moment date of the given date.
Discussion
For example, passing [NSDate date] for the date parameter would give you the start of “today.”
Special Considerations
If there were two midnights, this method returns the first. If there was none, it returns the first moment that did exist.
