Combine Date and Time into a Single Date iOS Swift 3

I had written a common method for combined date and time because if you set one date with only date and another one with Time only then if you want to combine both into a single date then follow the code

Code:

    func resetTime(forDate:NSDate,timedate:NSDate) ->Date {

        let df = DateFormatter()

        df.dateFormat = "dd MMM yyyy"

        var resultdate = Date()

        if let dateFromString = df.date(from: df.string(from: forDate as Date)) {

            

            let hour = NSCalendar.current.component(.hour, from: timedate as Date)

            let minutes = NSCalendar.current.component(.minute, from: timedate as Date)

            if let dateFromStringWithTime = NSCalendar.current.date(bySettingHour: hour, minute: minutes, second: 0, of: dateFromString) {

                let df = DateFormatter()

                df.dateFormat = "yyyy-MM-dd HH:mm:ss.SSS'Z"

                let resultString = df.string(from: dateFromStringWithTime)

                resultdate = df.date(from: resultString)!

            }

        }

        return resultdate

    }
