How to add minutes to current time in swift

by

Two approaches:

  1. Use Calendar and date(byAdding:to:wrappingComponents:). E.g., in Swift 3 and later:

    let calendar = Calendar.current
let date = calendar.date(byAdding: .minute, value: 5, to: startDate)

  2. Just use + operator (see +(_:_:)) to add a TimeInterval (i.e. a certain number of seconds). E.g. to add five minutes, you can:

    let date = startDate + 5 * 60

    (Note, the order is specific here: The date on the left side of the + and the seconds on the right side.)

    You can also use addingTimeInterval, if you’d prefer:

    let date = startDate.addingTimeInterval(5 * 60)

Bottom line, +/addingTimeInterval is easiest for simple scenarios, but if you ever want to add larger units (e.g., days, months, etc.), you would likely want to use the calendrical calculations because those adjust for daylight savings, whereas addingTimeInterval doesn’t.
