Highlight day if the date equal to date in array (JTAppleCalendar)

I have an array of object contains bookings

class MonthBookings: NSObject {

    var date: Date = Date()    
    var bookings_count: Int = 0
}

var bookings = [MonthBookings]()

So I need to check if cell date is equal to some date in bookings array then change cell color for this date in cell.

I have tried this way down below but didn't work:

func calendar(_ calendar: JTAppleCalendarView, willDisplayCell cell: JTAppleDayCellView, date: Date, cellState: CellState) {
    guard let sfbCell = cell as? SFBCalendarCell else {return}

    let booking = self.bookingsMonths[cellState.row()]

    if booking.date == date {
        sfbCell.dayText.textColor = .red
    } else {
        sfbCell.dayText.textColor = .black
    }
}

I Solved by using Contains method

if bookingsMonths.contains(where: { $0.date == cellState.date && $0.bookings_count != 0 }) {

      sfbCell.dayText.font = UIFont.boldSystemFont(ofSize: 15)

} else {

      sfbCell.dayText.font = UIFont.systemFont(ofSize: 15)

}
