prepare for segue.. from UITableView to DetailView with parse Objects

trying to get from my UITableViewController to the detail view controller with these PFObjects...thanks in advance!

error i can't seem to reconcile..."Cannot subscript a value of type 'String' with an index of type 'String'"

I want the queried objects to present on the detail view controller...

here is my query and my prepare for segue...i can't seem to access the objects in the prepare for segue...

    var customerName = [String]()
    var customerAddress = [String]()

  var query = Pfuser.query
  query.whereKey("userId",equalTo:adminFollowingUser)
  query.findObjectsInBackgroundWithBlock({ (adminObjects, error) -> Void in

          if let objects = adminObjects {

            for object in objects {

  self.customerName.append(object["customerName"] as! String)
  self.customerAddress.append(object["customerStreetAddress"] as! String)

// Here is the prepare for segue....

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

       let employeeDetailVC: EmployeeDetailViewController =  segue.destinationViewController
    as! EmployeeDetailViewController
  // indexPath is set to the path that was tapped


let indexPath = self.tableView.indexPathForSelectedRow

  let customerNameLabel = self.customerName[indexPath!.row]
  let customerAddressLabel = self.customerAddress[indexPath!.row]
 employeeDetailVC.customerString = customerNameLabel
  employeeDetailVC.addressString = customerAddressLabel

here is my detail view controller receiving the Strings. 

       //DetailViewController  

   var customerString = String()
   var addressString = String()

  override func viewDidLoad() {
super.viewDidLoad()

self.customerLabel.text = customerString
self.addressLabel.text = addressString

I would recommend using a PFQueryTableViewController. This is a UI object that is provided by Parse and loads data from your class 50x faster.

Here is an example of how to create it:

    import UIKit

class YourTableViewController: PFQueryTableViewController {

// Initialise the PFQueryTable tableview
override init!(style: UITableViewStyle, className: String!) {
    super.init(style: style, className: className)
}

required init(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)

    // Configure the PFQueryTableView
    self.parseClassName = "yourClass"

    self.textKey = "yourObject"
    self.pullToRefreshEnabled = true
    self.paginationEnabled = false
}

// Define the query that will provide the data for the table view
override func queryForTable() -> PFQuery! {
    var query = PFQuery(className: "yourClass")
    query.orderByAscending("yourObject")


    return query
}

//override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath, object: PFObject) -> PFTableViewCell {

    var cell = tableView.dequeueReusableCellWithIdentifier("Cell") as CustomTableViewCell!
    if cell == nil {
        cell = CustomTableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: "Cell")
    }

    // Extract values from the PFObject to display in the table cell

    cell.info.text = object["info"] as String


    // Date for cell subtitle
    var dateFormatter = NSDateFormatter()
    dateFormatter.dateFormat = "yyyy-MM-dd"
    let dateForText = object["date"] as NSDate
    cell.date.text = dateFormatter.stringFromDate(dateForText)

    return cell
}

// In a storyboard-based application, you will often want to do a little preparation before navigation
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {

    // Get the new view controller using [segue destinationViewController].
    var detailScene = segue.destinationViewController as YourDetailViewController

    // Pass the selected object to the destination view controller.
    if let indexPath = self.tableView.indexPathForSelectedRow() {
        let row = Int(indexPath.row)
        detailScene.currentObject = objects[row] as? PFObject
    }
}

At the end make sure to also created a custom cell class.

var currentObject = String() is a string and you set it to a string in the prepareForSegue.This should do the trick: self.customerTextField.text = curentObject And remove all the other stuff.

Try that 

    let nav = segue.destinationViewController as! CustomerDetailViewController
    var indexPath :NSIndexPath = self.tableview.indexPathForSelectedRow()!
        var object  = self.CustomerName[indexPath.row] as! String 
           nav.currentobject = object
