problem with yield WaitForSeconds()

Questions & Answers
1

I want to spawn a prefab after 2 seconds but I am having an issue with my yield function, here is the code:

using UnityEngine;
using System.Collections;

public class spawn : MonoBehaviour
{
	// Prefab to spawn
	public int distance = 10;
	public int timeDelay = 5;

	public float speed = 0.1f;

    public Transform clone;

	public GameObject spawnPoint;
	// Use this for initialization
	void Start()
	{

	}

	void Update()
	{
		transform.position += transform.forward * distance * speed;

		while (true) 
		{
            //My yield is showing up in red giving me an error
			yield WaitForSeconds(timeDelay);
			Instantiate (clone, spawnPoint.transform.position, spawnPoint.transform.rotation);
		}

	}
	
}

This is what the console returns:

You must use return before WaitForSeconds

yield return new WaitForSeconds(timeDelay);
