Custom cell / table view - swift

Question

I am trying to learn tableView and custom cell. I was able to find some tutorials.
However, I need to be able to have informations to go from a cell to another, when the users are editing informations.
I also have a problem implementing the code like an Alert view to work on a cell, even know it's working on a view controller.
Can someone guide me toward a tutorial, as I have difficulty to found one.

As I said in my comment, you're asking too many questions in one, anyway this is a small TableView tutorial:
First thing first, you need to create your tableview:
var tableView: UITableView!
then you'll add it to your view:
//Put these in your view did load
//Change tose vaues as you please
tableView = UITableView(frame: CGRect(x: 0.0, y: 0.0, width: UIScreen.main.bounds.width, height: 400), style: .plain)
view.addSubview(tableView)
So you'll need to register the cells:
tableView.register(UITableViewCell.self, forCellReuseIdentifier: "MyCell") //Choose the identifier you want but always use the same within a single Table view
You'll have to set the delegate and the data source:
//put these in your view did load
tableView.delegate = self
tableView = self
And your class will need to conform to these protocolls, so, you'll add the UITableViewDelegate and the UITableViewDataSource to it:
class MyViewController: UIViewController, UITableViewDelegate, UITableViewDataSource{}
So you'll have to set the protocol stubs as well:
//Here you'll decide the number of cells your tableView will have
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {}
//Here you'll decide the desired output of your cell (text, color ecc...)
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
//You have to create the cell first, it can be done as follows:
let cell = tableView.dequeueReusableCell(withIdentifier: "MyCell", for: indexPath) //Notice how I'm using the same identifier
return cell
}
There are plenty of other protocol stubs like:
//Use this to determine the behaviour of the cell when you tap it
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {}
//Use this to set the cell's height
private func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat{}
You can find more in the apple documentation.
