Always keep cell on the top of uitableview

I have an application that is viewbased and I am adding a uitableview as a subview to the main view. The uitableview is full with class Category cells. Everything works fine, but I want to have “Quick notes” Category always on the top of the uitableview. This means when I reloadData() in the Array, “Quick Notes” is always with index 0 and it goes on the bottom of the uitableview. And when I create new cell I need it to go under the “Quick Notes” section. Please help me, what code I need to achieve that functionality and where I need to put it. Thanks!

Edit: Thats where I am adding "Quick Notes" to the Realm database.

private let categories = try! Realm()

private init() {
    if categories.objects(Category.self).isEmpty {
        createCategoryWith(title: "Quick Notes", color: "#FF0000", icon: "quickNotes")
    }
}

Update the array in the ViewController:

func didCreateCategory(category: Category) {
    RealmHandler.shared.createCategoryWith(title: category.title, color: category.color, icon: category.icon)
    self.categories = RealmHandler.shared.getAllCategories()
    tableView.reloadData()
}

DataSourceDelegate:

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "categoryCell", for: indexPath)
    cell.textLabel?.text = categories[categories.count - (1+indexPath.row)].getTitle()
    cell.contentView.backgroundColor = hexStringToUIColor(hex: categories[categories.count-(1+indexPath.row)].getColor())
    return cell
}

use viewForHeaderInSection delegate method of tableView.

tableView(_ tableView: UITableView, viewForHeaderInSection section: Int)

here you can define your header cell. then implement your logic that what do you want to show on this cell. this headerCell will be always on top of your tableView.
