[Solved] Add 1 Day to a Date [closed]

by


The most reliable way to get the next occurrence of a time is nextDate(after:matching:matchingPolicy: of Calendar because it considers also daylight saving changes.

assuming datePicker is the NSDatePicker instance:

let date = datePicker.date

let calendar = Calendar.current
// get hour and minute components of the given date
let components = calendar.dateComponents([.hour, .minute], from: date)
// calculate the next occurrence of the date components from now
let nextOccurrence = calendar.nextDate(after: Date(), matching: components, matchingPolicy: .nextTime)
