Segue not sending correct cell info in Swift - swift

Question

I have a tableView that triggers a segue to a detail view when a cell is pressed. The table contains a list of users that the currentUser is friends with. Pressing the cell loads the view for that user (name, profile, etc). It's a very simple app I'm creating to learn how to program.
The problem is that when I press on a cell, it's always loading the user info for the last user in the table (and also happens to be the most recent "friend" that the user made). I have a feeling that the issue is with an if statement I have in the tableView function:
extension MatchesViewController: UITableViewDataSource
{
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
return numberOfMatches
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
let cell: UITableViewCell = tableView.dequeueReusableCellWithIdentifier("MatchCell", forIndexPath: indexPath)
if PFUser.currentUser()!.objectId == self.user1.objectId{
let user = matchesResults[indexPath.row]["user2"] as! PFUser
cell.textLabel?.text = user["first_name"] as! String
self.viewUser = user
}
if PFUser.currentUser()!.objectId == self.user2.objectId{
let user = matchesResults[indexPath.row]["user1"] as! PFUser
cell.textLabel?.text = user["first_name"] as! String
self.viewUser = user
}
return cell
}
}
Here's the segue code, but I don't think there is an issue with it (although I could be wrong):
extension MatchesViewController: UITableViewDelegate
{
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath)
{
self.performSegueWithIdentifier("UserSegue", sender: "viewUser")
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if (segue.identifier == "UserSegue") {
let destinationVC = segue.destinationViewController as! UserViewController
destinationVC.user = self.viewUser
}
}
}
Any ideas? If there is an issue with my tableView If statement, how can I fix it?
Thanks!

You can get the user object by indexPath, than pass it through the sender parameter of the performSegueWithIdentifier method
extension MatchesViewController: UITableViewDelegate
{
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath)
{
let user:PFUser?
if PFUser.currentUser()!.objectId == self.user1.objectId{
user = matchesResults[indexPath.row]["user2"] as! PFUser
}
if PFUser.currentUser()!.objectId == self.user2.objectId{
user = matchesResults[indexPath.row]["user1"] as! PFUser
}
self.performSegueWithIdentifier("UserSegue", sender: user)
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
// sender is the user object
if (segue.identifier == "UserSegue") {
let destinationVC = segue.destinationViewController as! UserViewController
destinationVC.user = sender // maybe you need cast sender to UserObject
}
}
}
