Question

In objective-c, the following code results in the UTC date time information using the date API.

NSDate *currentUTCDate = [NSDate date]
         


        

Answer 1

In addition to other answers, you can write an extension for Date class to get formatted Data in specific TimeZone to make it as utility function for future use. Like

 extension Date {

 func dateInTimeZone(timeZoneIdentifier: String, dateFormat: String) -> String  {
 let dtf = DateFormatter()
 dtf.timeZone = TimeZone(identifier: timeZoneIdentifier)
 dtf.dateFormat = dateFormat

 return dtf.string(from: self)
 }
}

Now you can call it like

 Date().dateInTimeZone(timeZoneIdentifier: "UTC", dateFormat: "yyyy-MM-dd HH:mm:ss");
