Passing data thru a Swift segue works every other time - swift

Question

I have a tableview which reads and RSS feed of episodic radio shows. I want the playlist for the selected show to pass to a second controller for viewing in a textview when a cell is selected. I am using a segue and it works when I select the same cell twice (every other time). I have searched everywhere without success and its driving me nuts! Please help. Here is my code
// Only grab the data at the selected cell
//
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
// Load the variable to hold whats in the row
currentList = feeds.objectAtIndex(indexPath.row).objectForKey("itunes:summary") as NSString
// Load the row number
myRow = (indexPath.row)
}
// Pass the data thru the segue
override func prepareForSegue(segue: (UIStoryboardSegue!), sender: AnyObject!) {
if (segue.identifier == "mySegue") {
// var vc = segue.destinationViewController as secondViewController
// vc.toPass = currentList
// println(vc.toPass)
let vc = segue.destinationViewController as secondViewController
let indexPath = self.tableView.indexPathForSelectedRow
vc.toPass = currentList
}
}
}
Here is the code from my second view controller
import UIKit
class secondViewController: UIViewController {
// Create a property to accept the data
#IBOutlet weak var textPlayList: UITextView!
// Create a variable to store the data
var toPass:String!
override func viewDidLoad() {
super.viewDidLoad()
textPlayList.text = toPass
textPlayList.textColor = UIColor .whiteColor()
textPlayList.font = UIFont .boldSystemFontOfSize(10)
}
}

The problem is that prepareForSegue happens before didSelectRowAtIndexPath so your currentList variable is set up too late for be useful in prepareForSegue.
To fix this, move this code:
// Load the variable to hold whats in the row
currentList = feeds.objectAtIndex(indexPath.row).objectForKey("itunes:summary") as NSString
to prepareForSegue:
override func prepareForSegue(segue: (UIStoryboardSegue!), sender: AnyObject!) {
if (segue.identifier == "mySegue") {
let vc = segue.destinationViewController as secondViewController
if let indexPath = self.tableView.indexPathForSelectedRow() {
let currentList = feeds.objectAtIndex(indexPath.row).objectForKey("itunes:summary") as NSString
vc.toPass = currentList
}
}
}
In general, you don't need didSelectRowAtIndexPath if you are using segues because prepareForSegue is where you set up the transition.
