Is there a daylight savings check in Swift?

Question

I need to check to see if the current date is during daylight savings time. In pseudocode that would be like this:

let date = NSDate()

if date.isDaylightSav         


        

Answer 1

Swift 4.0 or later

You can check a date isDaylightSavingTime in two ways by time zone identifier or abbreviation.

let timeZone = TimeZone(identifier: "America/New_York")!
if timeZone.isDaylightSavingTime(for: Date()) {
   print("Yes, daylight saving time at a given date")        
}

let timeZone = TimeZone(abbreviation: "EST")!
if timeZone.isDaylightSavingTime(for: Date()) {
   print("Yes, daylight saving time at a given date")     
}
