DidSelect after SearchController is used causes crash swift

I have a TableView and a Search Controller. They both work perfectly with regards to displaying the info, searching, etc. The problem arises when you go to select one of the cells.

In my code, there are 4 ways you can select the cell... If a bool isAboutNewPost == true / false, and if the search is active or not. If the search controller is active, I am using the data from a filtered array.

When you select a cell and the search controller is not active, it works perfectly. When you select a cell and the search controller is active, but the bool is false, it works perfectly. When you select a cell and the search controller is active and the bool is true, it crashes. I have no clue why, because it is almost identical code. 

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    //
    self.resultSearchController.endEditing(true)

    switch(segmentControl.selectedSegmentIndex)
    {
    case 0:
        if self.theResultSearchController.active {


            self.theResultSearchController.hidesNavigationBarDuringPresentation = false

            print("it is in search")
            let indexPath = tableView.indexPathForSelectedRow

            let currentCell = tableView.cellForRowAtIndexPath(indexPath!) as! NewAddPostTableViewCell
            theResultSearchController.active = false

            print("Going to Did Select Name!")
            //            self.performSegueWithIdentifier("transferToAddChinUp", sender: currentCell.name.text)

            let sb = UIStoryboard(name: "Main", bundle: nil)

            if self.isAboutNewPost == true {

                print("There was a new post.")
                let messagesVC = sb.instantiateViewControllerWithIdentifier("AddChinUpScreen") as! AddChinUpViewController
                messagesVC.userObjectId = currentCell.nameLabel.text
                messagesVC.thereWasJustANewPost = true
                print("i got to right here.")
                self.navigationController?.pushViewController(messagesVC, animated: true)

                // new line
                //self.performSegueWithIdentifier("transferToAddChinUp", sender: currentCell.nameLabel.text)

            } else {
                print("There wasn't a new post.")
                let messagesVC = sb.instantiateViewControllerWithIdentifier("AddChinUpScreen") as! AddChinUpViewController
                messagesVC.userObjectId = currentCell.nameLabel.text
                self.navigationController?.pushViewController(messagesVC, animated: true)
                //self.performSegueWithIdentifier("didSelectName", sender: currentCell.nameLabel.text)

            }

        } else {

            if self.isAboutNewPost == true {
                print("it is not in search")

                print("Going to transferToAddChinUp!")

I found the solution. It had to do with how the view was loaded in the first place. Commented out code was the original code. Fixed it by making it a modal segue. 

@IBAction func goToUnlockPost(sender: AnyObject) {

//        let vc = self.storyboard!.instantiateViewControllerWithIdentifier("NewAddPost") as! NewAddPostViewController
//        vc.isAboutNewPost = true
//        vc.comingFromUnlockPost = true
//        self.presentViewController(vc, animated: true, completion: nil)
    self.performSegueWithIdentifier("tappedUnlockPost", sender: nil)

}


override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if segue.identifier == "tappedUnlockPost" {

        let destinationNavigationController = segue.destinationViewController as! UINavigationController
        let targetController = destinationNavigationController.topViewController as! NewAddPostViewController

        //targetController = segue.destinationViewController as! NewAddPostViewController
        targetController.isAboutNewPost = true
        targetController.comingFromUnlockPost = true

    }
}
