iOS Calendar App Time Zone List

Question

As you can see in the screen below, iOS Calendar app shows the list of available time zone in City, Country format.

I want to attain the same list. Where can I get this list?

@HamDongKyun - take a look at a few of the "Related" links to the right... there are a couple already asking / discussing your question. — DonMag, Aug 15 '17 at 15:43

You cannot get a "City, County" format, but you can get a "City, Continent" format using this piece of code:

let timeZones = TimeZone.knownTimeZoneIdentifiers.flatMap{ id->String? in
    let components = id.components(separatedBy: "/")
    guard components.count == 2, let continent = components.first, let city = components.last else {return nil}
    return "\(city), \(continent)"
}

Output will be:

"Abidjan, Africa", "Accra, Africa", "Addis_Ababa, Africa", "Algiers, Africa", "Asmara, Africa", "Bamako, Africa", "Bangui, Africa", "Banjul, Africa"...

So basically, your answer is I can not get as what iOS calendar app is providing, right? – Ham Dong Kyun Aug 15 '17 at 15:32
Yes, this is the only thing you can get. – Dávid Pásztor Aug 15 '17 at 15:34
Then how is iOS Calendar App getting that list, in all the locale? Does it have a separate datastore not opened to the foundation API? – Ham Dong Kyun Aug 15 '17 at 15:35

Yes, most probably it is using a private API. – Dávid Pásztor Aug 15 '17 at 15:40

TimeZone has a static function knownTimeZoneIdentifiers which returns an array of String identifiers. Documentation

I know that documentation, but that does not show as the timezone shown like iOS calendar app – Ham Dong Kyun Aug 15 '17 at 15:32
