Method to stop enemies from spawning Unity5

I am developing a laser defender game as part of the course "Learn how to program in C# by developing games".

Here is the main function responsible for spawning enemies. I have the variable waves set to 3. Then I want to destroy the position of the space ships in order to not allow them to spawn. The issue is when I start the game there are no ships at all. (The method below is in the update Function)

 if (AllMembersDead())
 {
     for (float i = 0; i < waves; i++)
     {
         SpawnUntilFull();       // number of waves to be spawned
     }
     Destroy(position);
 }

Here is a picture of the gameObject. https://i.stack.imgur.com/a9pak.png

Here are the function for SpawnUntilFull() and AllMembersDead() if needed.

 bool AllMembersDead()
 {
     foreach(Transform childPositionGameObject in transform)
     {
         if (childPositionGameObject.childCount > 0)
         {
             return false;
         }
     }
     return true;
 }
 
 void SpawnUntilFull()
 {
     Transform freePosition = NextFreePosition();
     if (freePosition)
     {
         GameObject enemy = Instantiate(enemyPrefab, freePosition.transform.position, Quaternion.identity) as GameObject; // Instantiate (spawning or creating) enemy prefab (as gameobject assures that what its returning to us is no normal object but rather a game object)
         enemy.transform.parent = freePosition; // the transform of whatever thing the enemy is attached to, and that would be the enemyFormation GameObject
     }
 
     if (NextFreePosition())
     {
         Invoke("SpawnUntilFull", spawnDelay);
     }

I'm not sure what I'm doing wrong. Any guidance would be appreciated.
