Add section after 7 cell created in TableView - Swift

Question

I have 2 arrays, one that is containing the sections and another one that is containing the elements for populate the cells of my TableView.

The question is: is it possible to create multiple sections with title after 7 cells?

For example, the array contains 14 elements and sections array 2 elements. I wish that at the beginning will appear "Section 1" then first 7 elements, then "Section 2" then the rest of the elements.

Thank you!

        override func viewDidLoad() {

Update numberOfRowsInSection and cellForRowAt methods like this

func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
    return "Case \(section)"
}
func numberOfSections(in tableView: UITableView) -> Int {
    let lastSection = titleArray.count % 7 == 0 ? 0 : 1
    return (titleArray.count/7) + lastSection
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    let count = titleArray.count - (7*section)
    return min(7,count)
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "challengeCell", for: indexPath) as! ChallengeTableViewCell
    let rowIndex = (indexPath.section*7)+indexPath.row
    cell.labelTitle.text = titleArray[rowIndex]
    return cell
}
