在Swift 4.1你可以做:

func getDate() -> Date? {
    let dateFormatter = DateFormatter()
    dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss"
    dateFormatter.timeZone = TimeZone.current
    dateFormatter.locale = Locale.current
    return dateFormatter.date(from: "2015-04-01T11:42:00") // replace Date String
}

试试下面的日期格式。

let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "yyyy'-'MM'-'dd'T'HH':'mm':'ssZZZ"
let date = dateFormatter. dateFromString (strDate)

希望能有所帮助。

Swift 4.1:

let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy'-'MM'-'dd'T'HH':'mm':'ssZZZ"
let date = dateFormatter.date(from: strDate)

嗨，你有单独的T格式，然后转换为你喜欢

// create dateFormatter with UTC time format
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss"
dateFormatter.timeZone = NSTimeZone(name: "UTC")
let date = dateFormatter.dateFromString("2015-04-01T11:42:00")

// change to a readable time format and change to local time zone
dateFormatter.dateFormat = "EEE, MMM d, yyyy - h:mm a"
dateFormatter.timeZone = NSTimeZone.localTimeZone() 
let timeStamp = dateFormatter.stringFromDate(date!)

就用SwifterSwift吧。

stringDate = "2020-04-26T08:56:17.987Z"
let date = Date(iso8601String: stringDate)

斯威夫特5。看是否一个日期已经通过:

let expiryDate = "2020-01-10" // Jan 10 2020

let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd"

if Date() < dateFormatter.date(from: expiryDate) ?? Date() {
    print("Not Yet expiryDate")
} else {
    print("expiryDate has passed")
}

Convert the ISO8601 string to date let isoDate = "2016-04-14T10:44:00+0000" let dateFormatter = DateFormatter() dateFormatter.locale = Locale(identifier: "en_US_POSIX") // set locale to reliable US_POSIX dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ssZ" let date = dateFormatter.date(from:isoDate)! Get the date components for year, month, day and hour from the date let calendar = Calendar.current let components = calendar.dateComponents([.year, .month, .day, .hour], from: date) Finally create a new Date object and strip minutes and seconds let finalDate = calendar.date(from:components)

还可以考虑iOS 10 / macOS 10.12中引入的方便格式化程序ISO8601DateFormatter:

let isoDate = "2016-04-14T10:44:00+0000"

let dateFormatter = ISO8601DateFormatter()
let date = dateFormatter.date(from:isoDate)!
