WKInterfaceTable not creating rows

Question

I'm trying to build a simple WatchKit app with a Table. Each row has a Label. Here's my TableRowController class:

import WatchKit

class TaskTableRowController: NSObject {

    @IBOutlet var taskName: WKInterfaceLabel!
}

In my InterfaceController, I add a row to my Table and try to set the Label's text. However, taskList.rowController(at: 0) does not find a row, so the Label is unmodified.

import WatchKit
import Foundation

class InterfaceController: WKInterfaceController {

    @IBOutlet var taskList: WKInterfaceTable!

    override func awake(withContext context: Any?) {
        super.awake(withContext: context)

        // Configure interface objects here.
        taskList.setNumberOfRows(1, withRowType: "TaskRow")
        if let x = taskList.rowController(at: 0) as? TaskTableRowController
        {
            x.taskName.setText("Hello World")
        }
    }

    override func willActivate() {
        // This method is called when watch view controller is about to be visible to user
        super.willActivate()
    }

    override func didDeactivate() {
        // This method is called when watch view controller is no longer visible
        super.didDeactivate()
    }

}

Here's some screens from Interface Builder and the output:

Replace Following code, It works for me :

    taskList.setNumberOfRows(10, withRowType: "TaskRow")

    for index in 0..<taskList.numberOfRows {
        if let controller = taskList.rowControllerAtIndex(index) as? TaskTableRowController {
            controller.taskName.setText("Hello World")
        }
    }

I have seen the screen shots but pl. Cross check & Make sure below points :

WKInterfaceLabel(taskName) has an IBOutlet in your TaskTableRowController.
TaskTableRowController identifier is set to 'TaskRow'.
WKInterfaceTable(taskList) has an IBOutlet.
The custom class for your row 'TaskTableRowController' is set.

Hope it helps you !!!

Do let me know if you have any query.
