У меня есть UITableView, в который я поместил UICollectionView, а затем повторно использовал этот сценарий для 10 или более ячеек.

Я хочу, чтобы при прокрутке моего UICollectionView каждая из ячеек другого представления коллекции также прокручивалась одновременно синхронно.

MyViewController.swift

        ,"Auckland Standard Time","Melbourne Standard Time",
         "Manchester Standard Time","Paris Standard Time",
         "Alaska Standard Time","Greenland Standard Time"
        ,"Sutherland Standard Time","Russia Standard Time"]
    
    var array2 = ["desc","desc","desc","desc","desc"]
    
    var array3 = ["Mon","Tue","Wed","Thu", "Fri","Sat","Sun"]
    
    var array4 = ["12 2021","12 2021","12 2021","12 2021", "12 2021","12 2021","12 2021"]
    
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
