这是SWIFT扩展，以获得您当前的设备位置时间(GMT)。

func getGMTTimeDate() -> Date {
   var comp: DateComponents = Calendar.current.dateComponents([.year, .month, .day, .hour, .minute], from: self)
   comp.calendar = Calendar.current
   comp.timeZone = TimeZone(abbreviation: "GMT")!
   return Calendar.current.date(from: comp)!
}

现在得到时间:-

Date().getGMTTimeDate()

使用Swift 5 (Xcode 10 & Xcode 11)(来自法国UTC)

func getCurrentDateTime() {
    let now = Date()
    let formatter = DateFormatter()
    formatter.locale = Locale(identifier: "fr_FR")
    formatter.dateFormat = "EEEE dd MMMM YYYY HH:mm"
    myLabel.text = formatter.string(from: now)
    myLabel.font = UIFont(name: "HelveticaNeue-Light", size: 12)
    myLabel.textColor = UIColor.black
}

如果您只想显示日期，请设置formatter.dateFormat

formatter.dateFormat = "EEEE dd MMMM YYYY"

若要只显示小时，请更改格式化程序。dateFormat来

formatter.dateFormat = "HH:mm"

不要忘记在viewDidLoad上添加getCurrentDateTime()。

一行Swift 5.2

let date = String(DateFormatter.localizedString(from: Date(), dateStyle: .medium, timeStyle: .short))

你可以从Dateformatter获取

let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "dd/MM/yyyy"
let dateString = dateFormatter.string(from:Date())
print(dateString)

斯威夫特4:

extension Date
{
    func hour() -> Int
    {
    //Get Hour
    let calendar = Calendar.current
    let components = calendar.component(.hour, from: self)
    let hour = components

    //Return Hour
    return hour
    }


    func minute() -> Int
    {
    //Get Minute
    let calendar = Calendar.current
    let components = calendar.component(.minute, from: self)
    let minute = components

    //Return Minute
    return minute
        }
}

Swift让创建和使用扩展变得非常容易。我创建了一个sharedCode.swift文件，并在其中放入枚举、扩展名和其他有趣的东西。我创建了一个NSDate扩展来添加一些典型的功能，这是费力和丑陋的输入一遍又一遍:

extension NSDate
{
    func hour() -> Int
    {
        //Get Hour
        let calendar = NSCalendar.currentCalendar()
        let components = calendar.components(.Hour, fromDate: self)
        let hour = components.hour

        //Return Hour
        return hour
    }


    func minute() -> Int
    {
        //Get Minute
        let calendar = NSCalendar.currentCalendar()
        let components = calendar.components(.Minute, fromDate: self)
        let minute = components.minute

        //Return Minute
        return minute
    }

    func toShortTimeString() -> String
    {
        //Get Short Time String
        let formatter = NSDateFormatter()
        formatter.timeStyle = .ShortStyle
        let timeString = formatter.stringFromDate(self)

        //Return Short Time String
        return timeString
    }
}

使用这个扩展，你现在可以做一些事情，如:

        //Get Current Date
        let currentDate = NSDate()

        //Test Extensions in Log
        NSLog("(Current Hour = \(currentDate.hour())) (Current Minute = \(currentDate.minute())) (Current Short Time String = \(currentDate.toShortTimeString()))")

在上午11:51会写出来:

(当前小时= 11)(当前分钟= 51)(当前短时间字符串= 11:51 AM)
