How to adding day to Date with DateToolsSwift?

I'm using a package call DateToolsSwift. Now, whenever I want to add a day to a Date object, I would do like this

let date = Date().add(TimeChunk(seconds: 0, minutes: 0, hours: 0, days: 3, weeks: 0, months: 0, years: 0))

This code is too long and it does't feel right. So my question is, is this the way to do it in DateToolsSwift? Or I'm doing it wrong?

If you want an extended possibility to add any time you want in one shoot

extension Date {
    
    public enum DateElement {
        case seconds(Int)
        case minutes(Int)
        case hours(Int)
        case days(Int)
        case months(Int)
        case years(Int)
    }
    public func add(_ time: DateElement...) -> Date? {
        var dateComponent = DateComponents()
        for e in time {
            switch e {
            case .seconds(let seconds):
                dateComponent.second = seconds
            case .minutes(let minutes):
                dateComponent.minute = minutes
            case .hours(let hours):
                dateComponent.hour = hours
            case .days(let days):
                dateComponent.day = days
            case .months(let months):
                dateComponent.month = months
            case .years(let years):
                dateComponent.year = years
            }
        }
        return Calendar.current.date(byAdding: dateComponent, to: self)
    }
}

let somewhereLater = Date().add(.hours(2), .days(5), .months(1))

*Without using DateToolsSwift. For example, if you want to add 3 days to Jan 1, 1970

let aDate = Date(timeIntervalSince1970: 0)
var dateComponent = DateComponents()
dateComponent.day = 3
let next3Days = Calendar.current.date(byAdding: dateComponent, to: aDate)

Similarly, you can set aDate = Date() if you want to add days to today.

EDIT

Alternatively, from @CodeDifferent

let next3Days = Calendar.current.date(byAdding: .day, value: 3, to: aDate)!

The DateToolsSwift package defines extension methods in Integer+DateTools.swift which allow the simple creation of TimeChunks, e.g. 3.days or 2.weeks. Therefore you can do

let date = Date().add(3.days)

or, since DateToolsSwift also defines a custom + operator,

let date = Date() + 3.days
