Answer 1

//It works fine 
func getPageCount(TotalCount : Int) -> Int{
    var num = TotalCount
    let reminder = num % 50
    print(reminder)
    if reminder != 0{
        num = TotalCount/50
        num = num + 1

    }else{
        num = TotalCount/50
    }
    return num
}

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    let TotalPage =  self.getPageCount(TotalCount: Int(Datacount)!)
    let lastItem = self.mainArr.count - 1
    if indexPath.row == lastItem {
        print("IndexRow\(indexPath.row)")
        if self.page < TotalPage-1 {
            self.view_Loader.isHidden = false
            self.view_LoaderHeight.constant = 50
        self.page += 1
        self.YourAPI()
        }
    }
}`

This is now a little bit easier with the addition of a new protocol in iOS10: UITableViewDataSourcePrefetching
