I want to get access to the user-friendly Time Zone list that appears in the Settings > General > Date & Time. Can someone help in providing the code for this?

Get the current user time zone:

let currentTimeZone = TimeZone.current

Get all time zones:

let timeZoneIdentifiers = TimeZone.knownTimeZoneIdentifiers

Create time zone with identifier:

let berlin = TimeZone(identifier: "Europe/Berlin")!

Get city name of time zone:

let cityName = berlin.identifier.split(separator: "/").last!

Get all city names:

    let allCities = timeZoneIdentifiers.compactMap { identifier in
        return identifier.split(separator: "/").last
    }
