Is GameObject.FindWithTag Bad for Mobile Platforming?

The title says it all. Is GameObject.FindWithTag bad for Mobile gaming? I am making my first mobile game. I am making a tower defense game that will be universal on Android and IOS, Phones and Tablets.

Also does anyone have any extra tips?

Using GameObject.FindWithTag() isn’t going to break your game on mobile platforms. GameObject.Find() performs even worse. Also depending how many gameobjects are in your scene will determine how costly a search can be. Tip: Cache the results, so you don’t have to search for it again.
