Swift Month year pickerView with last 12 months

Question

I am having a filter on a tableView, that has a 'From' and 'To' Months selection.

Month selection, I mean, when I select Month, the datePicker should show Month Year only. And the list should contain last 12 months from today.

I looked at the default UIDatePicker but realized that it is not possible to get only Month-Year. (Reference answer from SO)

Further looking, I found this link that has a custom month-year picker but it shows future 15 years. And, upon selection of any row, nothing happens.

Can someone help me customize it to show last 12 months from today and fetch the result upon selection?

This is a simple example to get the last 12 months

var last12Months = [Date]()
let firstDayComponent = DateComponents(day: 1)
Calendar.current.enumerateDates(startingAfter: Date(), 
                 matching: firstDayComponent, 
                 matchingPolicy: .nextTime, 
                 direction: .backward, 
                 using: { (date, idx, stop) in
    if let date = date {last12Months.append(date) }
    if last12Months.count == 12 { stop = true }
})

print(last12Months)
let formatter = DateFormatter()
formatter.dateFormat = "MMMM yyyy"
print(last12Months.map({formatter.string(from: $0)}))
