If a range is supplied, the sequence terminates if the next result is not contained in the range. The starting point does not need to be contained in the range, but if the first result is outside of the range then the result will be an empty sequence.
func dates(byAdding component: Calendar.Component, value: Int = 1, startingAt start: Date, in range: Range<Date>? = nil, wrappingComponents: Bool = false) -> some Sendable & Sequence<Date>
Returns a sequence of Dates, calculated by adding a scaled amount of Calendar.Components to a starting Date.
