No Data in array github Api Swift - json

Question

How do I get the "names" from the if let statement into my tableview? The code triggers the else block right now. I am trying to parse the name data from the github api. Here's the code:
import UIKit
import Foundation
class ViewController: UITableViewController {
var tableArray = [String] ()
override func viewDidLoad() {
super.viewDidLoad()
self.tableView.dataSource = self
self.tableView.delegate = self
parseJSON()
}
func parseJSON () {
let url = URL(string: "https://api.github.com")
let task = URLSession.shared.dataTask(with: url!) {(data, response, error ) in
guard error == nil else {
print("returned error")
return
}
guard let content = data else {
print("No data")
return
}
guard let json = (try? JSONSerialization.jsonObject(with: content,
options: JSONSerialization.ReadingOptions.mutableContainers)) as?
[String: Any] else {
print("Not containing JSON")
return
}
if let array = json["name"] as? [String] {
self.tableArray = array
} else {
print("Name is blank")
}
print(self.tableArray)
DispatchQueue.main.async {
self.tableView.reloadData()
}
}
task.resume()
}
}
extension ViewController {
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath) as UITableViewCell
cell.textLabel?.text = self.tableArray[indexPath.row]
return cell
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return self.tableArray.count
}
}
Right now it's displaying "name is blank" in the console. I am trying to get the names of the users and display them in a tableview. Other url's seem to work, but I can't seem to figure out Github. Thanks for the help.

Your mistakes is.
1. Used wrong url.
2. Wrong mapping response
https://api.github.com Return Api list.
https://api.github.com/users/ Return user list.
Function fetchNameOfUsers
1. Implement request by use "user list" url.
2. Mapping the response by use "user list" structure.
func fetchNameOfUsers() {
guard let url = URL(string: "https://api.github.com/users") else {
return
}
let request = URLRequest(url: url)
URLSession.shared.dataTask(with: request) { data, response, error in
guard error == nil else {
return // Error
}
guard let data = data, let _ = response else {
return // No data
}
guard let json = try? JSONSerialization.jsonObject(with: data, options: []) as? [[String: Any]] else {
return // Not [String: Any] list
}
let nameOfUsers = json.compactMap {
$0["login"] as? String
}
let displayedNameOfUsers = nameOfUsers.joined(separator: ", ")
print(displayedNameOfUsers)
}.resume()
}
To see result call function fetchNameOfUsers.
fetchNameOfUsers()
