Swift Date with year, month, and day

Date+SyntaxSugar.swift

extension Date {

    static func with(calendar: Calendar = .current, year: Int, month: Int, day: Int) -> Date {
        // Because the `calendar` value is non-nil, it's safe to force unwrap the `date` value
        DateComponents(calendar: calendar, year: year, month: month, day: day).date!
    }
