如何在swift中从时间戳中获取日期格式

import Foundation

func getDateFromTimestamp(timestamp: TimeInterval) -> String {
    let date = Date(timeIntervalSince1970: timestamp)
    
    let dateFormatter = DateFormatter()
    dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
    
    let formattedDate = dateFormatter.string(from: date)
    return formattedDate
}

let timestamp: TimeInterval = 1631234567
let formattedDate = getDateFromTimestamp(timestamp: timestamp)
print(formattedDate)
