You need to do like this

UIDatePicker display Local DateTime but it returns UTC DateTime. So you need to convert it to Local for getting actual Local Date and time.

func GetLocalStringDateFromUTC(date:Date)-> String{

    let dateFormatter = DateFormatter()
    dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss" //Your date format
    dateFormatter.timeZone = TimeZone(abbreviation: "GMT+5:30") //Current time zone different
    let myString = dateFormatter.string(from: date) //according to date format your date string
    return myString //Convert String to Date
}

// For Get date from string
func GetDateFromString(date_string:String,dateFormat:String)-> Date{

    let dateFormatter = DateFormatter()
    dateFormatter.dateFormat = dateFormat //Your date format
    dateFormatter.timeZone = TimeZone(abbreviation: "GMT+0:00") //Current time zone
    let date = dateFormatter.date(from: date_string) //according to date format your date string
    return date! //Convert String to Date
}

// For Get time from Date
func GetTimefromDate(date_string:String,dateFormat:String)-> String{

    let dateFormatter_db = DateFormatter()
    dateFormatter_db.dateFormat = dateFormat
    let dateFormatter_eventDate = DateFormatter()
    dateFormatter_eventDate.dateFormat = "hh:mm a" //Your time format
    let date = dateFormatter_db.date(from: date_string)
    return dateFormatter_eventDate.string(from: date!)
}

Use like this

let date = datePicker.date  // Pass your DatePicker Date Here

print(GetLocalStringDateFromUTC(date: date)) // Local String Date from UTC
print(GetDateFromString(date_string: GetLocalStringDateFromUTC(date: date), dateFormat: "yyyy-MM-dd HH:mm:ss")) // Local Date() from UTC
print(self.GetTimefromDate(date_string: self.GetLocalStringDateFromUTC(date: datePicker.date), dateFormat: "yyyy-MM-dd HH:mm:ss")) // Local Time from UTC

Output:
