Something to be aware of is that the conversion loses microseconds precision. This is extremely important if we use these Date values for sorting and therefore ending up with incorrect order. Let\u2019s consider an iOS app which uses API for fetching a list of items and each of the item contains a timestamp used for sorting the list. Often, these timestamps have the ISO8601 format like <code>2024-09-21T10:32:32.113123Z<\/code>. Foundation framework has a dedicated formatter for parsing these strings: <a href=\"https:\/\/developer.apple.com\/documentation\/foundation\/iso8601dateformatter\">ISO8601DateFormatter<\/a>.
