Trying to move y coordinate

I am new to Unity. The code is in 2d and c#. I am trying to make it that when the player goes below they appear above and when the player goes above they appear below. Here is the error I get:

Assets/Scripts/Player.cs(23,43): error CS1612: Cannot modify a value type return value of UnityEngine.Transform.position'. Consider storing the value in a temporary variable Assets/Scripts/Player.cs(27,43): error CS1612: Cannot modify a value type return value ofUnityEngine.Transform.position'. Consider storing the value in a temporary variable

Here is my code that I am having problems with:

        if (transform.position.y > 5.5f)
        {
            transform.position.y=-10f;
        }
        if (transform.position.y < -10.5f)
        {
            transform.position.y=5;
        }

P.S. I know about Unity answers, I asked my question there about 10 hours ago and moderators still haven't approved yet. That is why I am here.

You can't directly use transform.position.y to set a value for it. Instead Unity is asking that you use some temporary value or simply write as following - 

if (transform.position.y > 5.5f)
{
    transform.position = new Vector3(transform.position.x, -10.0f, transform.position.z);
}
if (transform.position.y < -10.5f)
{
    transform.position = new Vector3(transform.position.x, 5.0f, transform.position.z);
}

Or if you want to use temporary variable, use this -

if (transform.position.y > 5.5f)
{
    Vector3 newPosition = new Vector3(transform.position.x, -10.0f, transform.position.z);
    transform.position = newPosition;
}
if (transform.position.y < -10.5f)
{
    Vector3 newPosition = new Vector3(transform.position.x, 5.0f, transform.position.z);
    transform.position = newPosition;
}

Both are same. But for convenience, i would go for first one here in your case.
