Swift - Array of URLs not working

I have three different arrays that hold information. One displays the section title, one displays the title of each cell, and one provides a link to the other viewController. I am using Swift btw.

But when I run it, all the cells use the first url in the array and not the rest of the url's.

Here is my code:

import UIKit

class FirstViewController: UIViewController, UITableViewDataSource, 
UITableViewDelegate {
    var headers = ["Bein Sports", "Sky Sports", "Alkass"]
    var channels = [["Bein Sports 1","Bein Sports 2","Bein Sports 3","Bein Sports 4","Bein Sports 5","Bein Sports 6","Bein Sports 7","Bein Sports 8","Bein Sports 9","Bein Sports 10","Bein Sports News"],
                    ["Sky Sports 1","Sky Sports 2","Sky Sports 3","Sky Sports 4","Sky Sports 5"], ["Alkass One", "Alkass Two", "Alkass Three", "Alkass Four", "Alkass Five"]]
    var links = ["https://google.ca","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com"]
    var myIndex: IndexPath?


    func numberOfSections(in tableView: UITableView) -> Int {
        return headers.count
    }

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

    func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
        return headers[section]
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
        cell.textLabel?.text = channels[indexPath.section][indexPath.row]
        return cell
    }

    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        myIndex = indexPath
        performSegue(withIdentifier: "segue", sender: self)
    }
}

Try possible solution.

You need to define both same as below .

var channels = [["Bein Sports 1","Bein Sports 2","Bein Sports 3","Bein Sports 4","Bein Sports 5","Bein Sports 6","Bein Sports 7","Bein Sports 8","Bein Sports 9","Bein Sports 10","Bein Sports News"],["Sky Sports 1","Sky Sports 2","Sky Sports 3","Sky Sports 4","Sky Sports 5"], ["Alkass One", "Alkass Two", "Alkass Three", "Alkass Four", "Alkass Five"]]

var links = [["https://google.ca","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com"],["https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com"],["https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com"]]

Get url as below

linkurl = links[indexPath.section][indexPath.row] as String

Seems you didn't used links array anywhere in your code.I didn't check this code hope it will work

let url:URL = URL(string: "http://google.ca")!

So the above url loaded statically while clicking all links which you provide in cell.

First add a variable to get selected cell link url in ChannelController.

let selcetedLink:String = ""

While performing segue in didSelectRowAt method pass corresponding url from link.To do that you need to override prepareForSegue add below code in your FirstViewController

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
   if segue.identifier == "segue" { // check your segue identifier
      let theDestination = (segue.destinationViewController as ChannelController)
      theDestination.selcetedLink = self.links[myIndex.row]
    }
}

Finally use the selectedLink value to load URL request

let url:URL = URL(string: selectedLink )!

myIndex = [indexPath.section][indexPath.row]

is missing the collection you want to subscript. You perhaps meant:

myIndex = channels[indexPath.section][indexPath.row]
