Get indexPath of "next" UITableViewCell

Question

I have some code when tapping on a cell of a table view. Under certain circumstances I want to call the function tableView(_, didSelectRowAtIndexPath) recursively for the next cell. That means that when I selected row 5, I want to select row 6, etc.

How can I get the indexPath of the next cell based on another row?

Here's an answer in Swift:

private func nextIndexPath(for currentIndexPath: IndexPath, in tableView: UITableView) -> IndexPath? {
    var nextRow = 0
    var nextSection = 0
    var iteration = 0
    var startRow = currentIndexPath.row
    for section in currentIndexPath.section ..< tableView.numberOfSections {
        nextSection = section
        for row in startRow ..< tableView.numberOfRows(inSection: section) {
            nextRow = row
            iteration += 1
            if iteration == 2 {
                let nextIndexPath = IndexPath(row: nextRow, section: nextSection)
                return nextIndexPath
            }
        }
        startRow = 0
    }

    return nil
}

I use this code because I have a tableview with custom cells that contain a UITextField. It's configured with a Next button, and when that button is tapped, the focus is moved to the next UITextField.

To go to the previous indexPath, see this answer: https://stackoverflow.com/a/56867271/

For an example project that includes a previous/next button as a toolbar above a keyboard, check out the example project: https://github.com/bvankuik/TableViewWithTextFieldNextButton
