Solved
This worked:
currentInstructionIndex += 1
let indexPathTest = IndexPath(row: currentInstructionIndex, section: 0)
tableView.scrollToRow(at: indexPathTest, at: UITableView.ScrollPosition.top, animated: true)
The tableView.scrollToRow method is what I was looking for. More info here for anyone who’s interested: https://developer.apple.com/documentation/uikit/uitableview/scrollposition
