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

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"
