嘗試這個，

let dateStr = "2017-01-03T10:45:00.000+02:00"

let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd\'T\'HH:mm:ss\'.000\'z"
dateFormatter.timeZone = NSTimeZone(name: "UTC") as TimeZone!
let date = dateFormatter.date(from: dateStr)

print("Date from String : \(date)")

dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss xxxx'"
dateFormatter.timeZone = NSTimeZone(forSecondsFromGMT: 7200) as TimeZone!

print("String From Date : \(dateFormatter.string(from: date!))")

結果：

字符串中的日期：可選（2017-01-03 08:45:00 +0000）

字符串起始日期：2017-01-03 10:45:00 +0200

這個對我有用，希望對你有幫助

 let dateString = "2017-01-03 08:45:00 +0000"

// create dateFormatter with UTC time format
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss xxxx"
dateFormatter.timeZone = NSTimeZone(name: "UTC") as TimeZone!
let date = dateFormatter.date(from: dateString)// create   date from string
print("Date1 : \(date)")
// change to a readable time format and change to local time zone
dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss xxxx'"
dateFormatter.timeZone = NSTimeZone(forSecondsFromGMT: 7200) as TimeZone!
print("Date2 : \(dateFormatter.string(from: date!))")   

Answer 3

如果要將String轉換為Date，請嘗試以下代碼，並告訴我，

let dateString = "2016-10-25"
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd"
let FormatDate = dateFormatter.dateFromString(dateString)
print(FormatDate)

您還可以通過以下格式獲取更多時間：

dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
