You could subtract minutes using the Calendar :
Calendar.current.date(byAdding: .minute, value: -10, to: yourDate)

Use Calendar of iOS.
let beforeThreeMinutes = Calendar.current.date(byAdding: .minute, value: -3, to: datePicker.date)

Date from DatePicker can be in any format, that should not cause any issue. – Sundeep Saluja Jul 16 '19 at 11:58
