Next VC is not showing - ios

Question

I have a segue going from the first VC clubSelectionViewController to the one shown below clubSummaryViewController, but I have to click back 2 times to get the next VC to show. What am I doing wrong?
import Foundation
import UIKit
class clubSelectionViewController: UIViewController, UITableViewDelegate {
var clubsForSelection = [clubObject]()
var clubForClubSummaryView = [clubObject]()
#IBAction func selectDanceClubs(sender: AnyObject) {
clubForClubSummaryView = clubDataFilter.removeStripClubsFrom(clubsForSelection)
self.performSegueWithIdentifier("ClubSummary", sender: self)
}
#IBAction func selectStripClubs(sender: AnyObject) {
clubForClubSummaryView = clubDataFilter.removeDanceClubsFrom(clubsForSelection)
self.performSegueWithIdentifier("ClubSummary", sender: self)
}
override func viewDidLoad() {
super.viewDidLoad()
// everytime screen loads it removes information to give blank screen it removes all clubs in array
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "ClubSummary" {
let summaryView = segue.destinationViewController as! clubSummaryViewController
summaryView.clubDetails = [clubObject]()
summaryView.clubDetails = self.clubForClubSummaryView
}
}
}
Second VC
import UIKit
class clubSummaryViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
var clubDetails = [clubObject]()
var selectedClub = clubObject()
#IBOutlet var clubSummaryTableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
//Declare Delegate, Load TableView
clubSummaryTableView.delegate = self
//clubSummaryTableView.dataSource = self
clubSummaryTableView.reloadData()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
//MARK: TableViewDelegate
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return self.clubDetails.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = self.clubSummaryTableView.dequeueReusableCellWithIdentifier("SummaryCell")! as? clubSummaryCell
cell?.clubName.text = clubDetails[indexPath.row].clubName
cell?.clubAddress.text = clubDetails[indexPath.row].clubAddress
//TODO: insert image
cell?.clubPhoto.image = clubDetails[indexPath.row].clubImage.image
return cell!
}
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
self.selectedClub = self.clubDetails[indexPath.row]
self.performSegueWithIdentifier("ClubDetails", sender: self)
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "ClubDetails"{
let clubDetailsView = segue.destinationViewController as? clubInfoViewController
clubDetailsView?.clubForDetails = self.selectedClub
}
}
}

Answer 1

I think the problem in the:
#IBAction func selectDanceClubs(sender: AnyObject) {
clubForClubSummaryView = clubDataFilter.removeStripClubsFrom(clubsForSelection)
self.performSegueWithIdentifier("ClubSummary", sender: self)
}
#IBAction func selectStripClubs(sender: AnyObject) {
clubForClubSummaryView = clubDataFilter.removeDanceClubsFrom(clubsForSelection)
self.performSegueWithIdentifier("ClubSummary", sender: self)
}
I not sure why you want these two func have the same SegueWithIdentifier

Answer 2

The reason might be that you have attached the segue from the button itself.
That means when you click on button the segue from the button is getting called, and since you have action of the button also, the segue is called again from the action method.
Means, the same segue is called twice.
