如何将JSON解析为Swift中的tableView？

Question

Please give me advise, I can not figure out how to parse data in a table view properly.

Here is my model:

struct ContinentRoot: Codable {
let links: ContinentMiddle 
}

struct ContinentMiddle: Codable {
let continentItems: [ContinentsResponse]
}

struct ContinentsResponse: Codable {
let name: String
let href: String
}

In ViewController I add tableView, continentsArray ([ContinentRoot]) and do some regular things for networking. I guess that the problem may be here, because in the networking method everything seems normal:

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return continentsArray.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "ContinentsTableViewController", for: indexPath)
    let model = continentsArray[indexPath.row].links.continentItems[indexPath.row].name
    cell.textLabel?.text = model
    return cell
}

Thank you so much for for attention!

According to your attachment design:

if continentsArray is an array of "ContinentRoot" s. and you want to show the links in the selected ContinentRoot you must first select it, and use it like below:

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return selectedContinent.links.continentItems.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "ContinentsTableViewController", for: indexPath)
    let model = selectedContinent.links.continentItems[indexPath.row].name
    cell.textLabel?.text = model
    return cell
}  

if Not you must use your code and change this line:

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "ContinentsTableViewController", for: indexPath)
    
let selectedIndex = .zero // or every index you want
    let model = continentsArray[indexPath.row].links.continentItems[selectedIndex].name
    cell.textLabel?.text = model
    return cell
}
