Convert UTC date to any formatter easily

We are going to use ISO8601DateFormatter for this conversion. More about for this formattter.

Let's take a simple example :

Suppose we have this date string : “1975–05–21T07:00:00Z”

Small cheat sheet for date formatters:

Now we want our output in this format like “EEEE, MMM d, yyyy”

    static func releaseDateStr(_ releaseDate: String?) -> String {
        guard let releaseDate = releaseDate else {return ""}
        let utcISODateFormatter = ISO8601DateFormatter()

        // Printing a Date
        let date = Date()
        print(utcISODateFormatter.string(from: date))

        // Parsing a string timestamp representing a date
        let utcDate = utcISODateFormatter.date(from: releaseDate)
        
        let formatter = DateFormatter()
        formatter.dateFormat = "EEEE, MMM d, yyyy"
        
        if let date = utcDate {
            return formatter.string(from: date)
        }
        return ""
    }

That’s all, you got what you want

Happy Coding !!
