These 2 extensions convert a String to Date, and back to String

Convert Date To Month-Year Format.swift

extension Date {
//2    
    func convertToMonthYearFormat() -> String {
        let dateFormatter = DateFormatter()
        dateFormatter.dateFormat = "MMM yyyy"
        return dateFormatter.string(from: self)
    }
}


extension String {
//1 
    func convertToDate() -> Date? {
        let dateFormatter = DateFormatter()
        dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ssZ"
        dateFormatter.locale = Locale(identifier: "en_US_POSIX")
        dateFormatter.timeZone = .current

        return dateFormatter.date(from: self)
    }
//3
    func convertToDisplayFormat() -> String {
        guard let date = self.convertToDate() else { return "N/A" }
        return date.convertToMonthYearFormat()
    }
}

// Using it:
self.dateLabel.text = "On GitHub since \(user.createdAt.convertToDisplayFormat())"

Yo thanks so much!
