IndexOutOfRangeException only on iOS! Android / PC is ok!!

Hello everybody!

I have a problem that is driving me crazy! I'm generating a three-dimensional array, and when I run inside the Unity, or Android, everything works perfectly.

But when I run on iOS, happens IndexOutOfRangeException error when creating the array!

Anyone have any idea why?

 void GenerateWorldData () {
         WorldData = new byte[Width, Height, Depth];
         _perlingNoise = new PerlingNoise(Seed, 15);
 
         Debug.Log(WorldData.GetLength(0) + "," + WorldData.GetLength(1) + "," + WorldData.GetLength(2));
 
         for (int x = 0; x < Width; x++)
         {
             for (int y = 0; y < Height; y++)
             {
                 for (int z = 0; z < Depth; z++)
                 {
                     if (y >= 24 && y <= 24 + 2)
                     {
                         WorldData[x, y, z] = (byte)VoxelType.Occlusion;
                     }
                     else
                     {
                         int stone = _perlingNoise.GetPerlingNoise(x, z, 18) + 15;
                         int dirt = stone + _perlingNoise.GetPerlingNoise(x, z, 8) + 10;
                         int grass = dirt + 1;
 
                         if (y <= stone) 
                         {
                             WorldData[x, y, z] = (byte)VoxelType.Stone;
                         }
                         else if(y <= dirt)
                         {
                             WorldData[x, y, z] = (byte)VoxelType.Dirt;
                         }
                         else if(y <= grass)
                         {
                             WorldData[x, y, z] = (byte)VoxelType.Grass;
                         }
                         else
                         {
                             WorldData[x, y, z] = (byte)VoxelType.Air;
                         }
                     }
                 }
             }
             Debug.Log(x);
         }
 
         Debug.Log("Finished");
     }

And this is the error that appears on the xCode console:

 IndexOutOfRangeException: Array index is out of range.
