how to access time in swift code example

Example 1: swift get current hour

let date = Date() // save date, so all components use the same date
let calendar = Calendar.current // or e.g. Calendar(identifier: .persian)

let hour = calendar.component(.hour, from: date)
let minute = calendar.component(.minute, from: date)
let second = calendar.component(.second, from: date)

Example 2: swift get current hour

let formatter = DateFormatter()
formatter.dateFormat = "hh a" // "a" prints "pm" or "am"
let hourString = formatter.string(from: Date()) // "12 AM"
