How to select both single and multiple date in MultiDatePicker in SwiftUI

I am new in SwiftUI and I am facing problem with selecting Single date with MultiDatePicker

my code is like this

    @State private var dateRange: ClosedRange<Date>? = nil
    
    var body: some View {
    MultiDatePicker(dateRange: self.$dateRange)
    
     Button(action: {
        withAnimation(.linear(duration: 0.3)) {
          getDateRangeGuest(dateRange: dateRange)
         }
     }, label: {
         Text("OK")
           .font(.title3)
      })
    }
    
    func getDateRangeGuest(dateRange: ClosedRange<Date>?){
       if let range = dateRange {
          var newRange = String()
          newRange = "\(range)"
          print(newRange)
       }else{
        print(dateRange)
     }
}

Is it is possible to select also a Single date in MultiDatePicker?

I want it in range not in Set<DateComponents> array

I use WWCalendarTimeSelector calender. As it is in Swift I finally created its SwiftUI Version

    import SwiftUI
    import WWCalendarTimeSelector
    
    class CalendarSelectorDelegate: WWCalendarTimeSelectorProtocol {
        @Binding var singleDate: Date?
        @Binding var selectedDateString: String
        @Binding var multipleDates: [Date]
        @Binding var startDateGlobal: String
        @Binding var endDateGlobal: String
        
        init(singleDate: Binding<Date?>, selectedDateString: Binding<String>, multipleDates: Binding<[Date]>, startDateGlobal: Binding<String>, endDateGlobal: Binding<String>) {
            _singleDate = singleDate
            _selectedDateString = selectedDateString
            _multipleDates = multipleDates
            _startDateGlobal = startDateGlobal
            _endDateGlobal = endDateGlobal
        }
        
        func WWCalendarTimeSelectorDone(_ selector: WWCalendarTimeSelector, date: Date) {
            print("Selected \n\(date)\n---")
            singleDate = date
            selectedDateString = date.stringFromFormat("dd/MM/yyyy")
        }
        
        func WWCalendarTimeSelectorDone(_ selector: WWCalendarTimeSelector, dates: [Date]) {
            print("Selected Multiple Dates \n\(dates)\n---")
            
            var startDateSend = String()
            var endDateSend = String()
            
            if let date = dates.first {
                singleDate = date
                let firstDate = date.stringFromFormat("yyyy-MM-dd")
                let newDate = dates.last
                let lastDate = newDate!.stringFromFormat("yyyy-MM-dd")
                selectedDateString = "\(firstDate) - \(lastDate)"
                startDateSend = date.stringFromFormat("yyyy-MM-dd")
                endDateSend = newDate!.stringFromFormat("yyyy-MM-dd")
            } else {
                selectedDateString = "No Date Selected"
            }
            
            print("Label Value = ", selectedDateString)
            multipleDates = dates
            startDateGlobal = startDateSend
            endDateGlobal = endDateSend
        }
    }
    
    struct ContentView: View {
        @State private var singleDate: Date?
        @State private var selectedDateString = ""
        @State private var multipleDates: [Date] = []
        @State private var startDateGlobal = ""
        @State private var endDateGlobal = ""
        
        var body: some View {
            VStack {
                Text(selectedDateString)
                    .padding()
                
                Button(action: {
                    showCalendar()
                }) {
                    Text("Select Date")
                }
            }
        }
        
        func showCalendar() {
            let selector = WWCalendarTimeSelector.instantiate()
selector.optionSelectionType = WWCalendarTimeSelectorSelection.range
            let delegate = CalendarSelectorDelegate(singleDate: $singleDate, selectedDateString: $selectedDateString, multipleDates: $multipleDates, startDateGlobal: $startDateGlobal, endDateGlobal: $endDateGlobal)
            selector.delegate = delegate
            
            if let scene = UIApplication.shared.connectedScenes.first as? UIWindowScene {
                scene.windows.first?.rootViewController?.present(selector, animated: true, completion: nil)
            }
        }
    }
