In this short blog post, I am going to share with you a few code examples on how to work with dates in Swift. I will use DateComponents to add more days, months, or years to the current Date object in Swift.
Adding Date
let monthsToAdd = 2 let daysToAdd = 1 let yearsToAdd = 1 let currentDate = Date() var dateComponent = DateComponents() dateComponent.month = monthsToAdd dateComponent.day = daysToAdd dateComponent.year = yearsToAdd let futureDate = Calendar.current.date(byAdding: dateComponent, to: currentDate) print(currentDate) print(futureDate!)
Or you can do it this way:
let monthsToAdd = 2 var newDate = Calendar.current.date(byAdding: .month, value: monthsToAdd, to: Date()) newdate = Calendar.current.date(byAdding: .day, value: daysToAdd, to: newDate!) print(newDate)
Adding Date and Time
Or we can use DateComponents and set hours, minutes, and seconds as well:
import UIKit class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() let monthsToAdd = 2 let daysToAdd = 1 let yearsToAdd = 1 let currentDate = getCurrentDate() var dateComponent = DateComponents() dateComponent.month = monthsToAdd dateComponent.day = daysToAdd dateComponent.year = yearsToAdd let futureDate = Calendar.current.date(byAdding: dateComponent, to: currentDate) print(currentDate) print(futureDate!) } func getCurrentDate()-> Date { var now = Date() var nowComponents = DateComponents() let calendar = Calendar.current nowComponents.year = Calendar.current.component(.year, from: now) nowComponents.month = Calendar.current.component(.month, from: now) nowComponents.day = Calendar.current.component(.day, from: now) nowComponents.hour = Calendar.current.component(.hour, from: now) nowComponents.minute = Calendar.current.component(.minute, from: now) nowComponents.second = Calendar.current.component(.second, from: now) nowComponents.timeZone = NSTimeZone.local now = calendar.date(from: nowComponents)! return now as Date } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() // Dispose of any resources that can be recreated. } }
