Change the transition destination screen by cell in tableviewcell

Hello, I was able to display multiple cells using tableView in Xcode.
And I would like to change the screen transition destination for each cell.
If you tap a cell using the Navigation Controller, the screen will change, but no matter which cell you choose, it will transition to the same screen.

From here, how do I change the screen transition destination for each cell?

The following programs are written in viewController:

class ViewController:UIViewController, UITableViewDelegate, UITableViewDataSource{

    @IBOutlet weak variableView:UITableView!

    letmath: [String] = ["Mathematics I", "Mathematics A", "Mathematics II", "Mathematics B", "Mathematics III", "Mathematics C"]

    functableView(_tableView:UITableView, numberOfRowsInSection section:Int) - > Int{
        return path.count
    }

    functableView(_tableView:UITableView, cellForRowAtindexPath:IndexPath) - >UITableViewCell{
        letcell:UITableViewCell=tableView.dequeueReusableCell(withIdentifier: "beginnerCell", for:indexPath)
        cell.textLabel!.text=math [indexPath.row]
        return cell
    }

    override func viewDidLoad(){
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from anib.
    }

    override funcdidReceiveMemoryWarning(){
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

}

How do I change the screen transition destination for each cell?

When each cell is tapped, the following UITableViewDelegate Protocol methods are called:

 functableView(_tableView:UITableView, didSelectRowAtindexPath:IndexPath){
}

The indexPath argument determines which cell was tapped, which branches the process.

Here are some specific code examples:

 functableView(_tableView:UITableView, didSelectRowAtindexPath:IndexPath){
    switch indexPath.row {
    case0:
        // Cell-Tap Processing of Mathematics I
        // The following is an example of a screen transition of mathematics I in Segue.
        self.performSegue(withIdentifier: "toMath1View", sender:nil)
    case1:
        // When you're in math A
        ...(Same as above, the process of transitioning to the screen of mathematics A)
    case2:
        // Math II Self-Tap Time
        ...(Transition to Mathematics II screen as above)
    case3:
        // When you're in math B, when you're in the cell tap,
        ...(Transition to math B screen as above)
    case4:
        // Math III When Self-Tap
        ...(Transition to Mathematics III screen as above)
    case5:
        // When you self-tap math C
        ...(Same as above, the process of transitioning to the screen of mathematics C)
    }
}

Also, it is not good to write a direct value like case0, considering the serviceability of the code, so I think it would be good to define enum as follows.

// Mathematics Subjects
///
/// -math1: Mathematics I
/// -mathA: Mathematics A
/// -math2 - Mathematics II
/// -mathB: Mathematics B
/// -math3: Mathematics III
/// -mathC: Mathematics C
enum MathCourse:Int{
    case path1 = 0
    case pathA
    case path2
    case pathB
    case path3
    case pathC

    /// Transition destination segment identifier
    varseugeIdentifier: String {
        switchself{
        case.math1:
            return "toMath1"
        case.mathA:
            return "toMathA"
        case.math2:
            return "toMath2"
        case.mathB:
            return "toMathB"
        case.math3:
            return "toMath3"
        case.mathC:
            return "toMathC"
        }
    }

Use it as follows:

 switch indexPath.row {
caseMathCourse.math1:
    // Cell-Tap Processing of Mathematics I
    // The following is an example of a screen transition of mathematics I in Segue.
    self.performSegue (withIdentifier: MathCourse.math1.seugeIdentifier, sender:nil)
caseMathCourse.mathA:
    ・・・
