Answer 1

In Swift 3 and above

extension Date {
    var startOfDayDate: Date {
        return Calendar.current.startOfDay(for: self)
    }

    var endOfDayDate: Date {
        let nextDayDate = Calendar.current.date(byAdding: .day, value: 1, to: self.startOfDayDate)!
        return nextDayDate.addingTimeInterval(-1)
    }
}

Usage:

var currentDayStart = Date().startOfDayDate
var currentDayEnd = Date().endOfDayDate
