How to get time (hours, minutes, seconds) in SWIFT 3?

let date = NSDate()
let calendar = NSCalendar.currentCalendar()
let components = calendar.components(.Hour, fromDate: date)
let hour = components.hour

let date = Date()
let calendar = Calendar. current

let hour = calendar.component(.hour, from: date)
let minutes = calendar.component(.minute, from: date)
let seconds = calendar. component(.second, from: date)
print("hours = \(hour):\(minutes):\(seconds)")

How to determine the hour, minute and second of the NSDate class in Swift 3?

In Swift 2:

let date = NSDate()
let calendar = NSCalendar.currentCalendar()
let components = calendar.components(.Hour, fromDate: date)
let hour = components.hour

Swift 3?

In Swift 3.0, Apple removed the “NS” prefix and made everything simple. The following is to get the hours, minutes and seconds from the’Date’ class的方法(NSDate alternate)

let date = Date()
let calendar = Calendar.current

let hour = calendar.component(.hour, from: date)
let minutes = calendar.component(.minute, from: date)
let seconds = calendar.component(.second, from: date)
print("hours = \(hour):\(minutes):\(seconds)")

Like these, you can get the era, year, month, date, etc. in a corresponding way.
