How to add minutes to current time in swift

Question

I am new to Swift and am trying a scheduler. I have the start time selected and I need to add 5 minutes (or multiples of it) to the start time and display it in an UILabel?<

Answer 1

I think the simplest will be

let minutes = Date(timeIntervalSinceNow:(minutes * 60.0))

Answer 2

In case you want unix timestamp

        let now : Date = Date()
        let currentCalendar : NSCalendar = Calendar.current as NSCalendar

        let nowPlusAddTime : Date = currentCalendar.date(byAdding: .second, value: accessTime, to: now, options: .matchNextTime)!

        let unixTime = nowPlusAddTime.timeIntervalSince1970

Answer 3

You can use Calendar's method

func date(byAdding component: Calendar.Component, value: Int, to date: Date, wrappingComponents: Bool = default) -> Date?

to add any Calendar.Component to any Date. You can create a Date extension to add x minutes to your UIDatePicker's date:

Xcode 8 and Xcode 9 • Swift 3.0 and Swift 4.0

extension Date {
    func adding(minutes: Int) -> Date {
        return Calendar.current.date(byAdding: .minute, value: minutes, to: self)!
    }
}

Then you can just use the extension method to add minutes to the sender (UIDatePicker):

let section1 = sender.date.adding(minutes: 5)
let section2 = sender.date.adding(minutes: 10)

---

Playground testing:

Date().adding(minutes: 10)  //  "Jun 14, 2016, 5:31 PM"

Answer 4

You can use in swift 4 or 5

    let date = Date()
    let dateFormatter = DateFormatter()
    dateFormatter.dateFormat = "yyyy-MM-dd H:mm:ss"
    let current_date_time = dateFormatter.string(from: date)
    print("before add time-->",current_date_time)

    //adding 5 miniuts
    let addminutes = date.addingTimeInterval(5*60)
    dateFormatter.dateFormat = "yyyy-MM-dd H:mm:ss"
    let after_add_time = dateFormatter.string(from: addminutes)
    print("after add time-->",after_add_time)

output:

before add time--> 2020-02-18 10:38:15
after add time--> 2020-02-18 10:43:15
