Does anyone know of a way to get a users time zone in Swift?
I'm getting a specific time something is on t.v. out of a database and then need to subtract/add from where they are located to show them the correct time it's on.
How to get a user's time zone?

To retrieve the current user time zone, use the code below.
TimeZone.current.abbreviation()!
Other Date Formate here.

Objective-C
NSTimeZone *timeZone = [NSTimeZone localTimeZone];
NSString *tzName = [timeZone name];
Swift
let tzName = TimeZone.current.identifier
The name will be something like "Australia/Sydney", or "Europe/Lisbon".
Since it sounds like you might only care about the continent, that might be all you need.

Swift 4, 4.2 & 5
var gmtHoursOffset : String = String()
override func viewDidLoad() {
super.viewDidLoad()
gmtHoursOffset = getHoursFromGmt()
print(gmtHoursOffset)
}
func getHoursFromGmt() -> String {
let secondsFromGmt: Int = TimeZone.current.secondsFromGMT()
let hoursFromGmt = (secondsFromGmt / 3600)
return "\(hoursFromGmt)"
}
