When you assign this property a value of
true, you instruct ARKit to compute a value for
estimated for a person's body anchor. ARKit must know the physical height of a person in the real world to accurately estimate the person's real-world position. You enable this property to tell ARKit to estimate a recognized person's physical height before it assigns the body anchor's position.
