How to make enemy prefab spawn at random times between 1.0f to 10.0f.

Question

I am trying to make my enemy prefab spawn from a spawn point (which I have already achieved) at random times between 1.0f to 10.0f. Here is my code right now.........

{

 public GameObject prefabToSpawn;

 float spawnTime;




 private void Start()
 {
     spawnTime = Random.Range(0.0f, 10.0f);
     InvokeRepeating("Spawn", 5f, spawnTime);
 }



 void Spawn()
 {
     Instantiate(prefabToSpawn, transform.position, Quaternion.identity);
     Debug.Log("enemy spawned");
 }

}

Right now the code successfully randomly picks a number between 1 and 10 and uses that as the time to spawn the enemies one after the other, but the thing is is that once it chooses a random value between 1 and 10, the value is always the same, and therefore there is no randomness to the enemies' spawn time one after the other.

I would like the value of "spawnTime" to change to a new value (from 1.0f to 10.0f) every time after the prefab is spawned.

Use a coroutine. https://docs.unity3d.com/Manual/Coroutines.html

 IEnumerator SpawnEnemies() {
     float SpawnTimer;
     while (true) {
         SpawnTimer = Random.Range(1f, 10f);
         yield return new WaitForSeconds(SpawnTimer);
         // Actual spawning goes here
     }
 }
