-The first two properties specify the horizontal and vertical alignment, respectively, of the box view's subviews. Horizontal alignment options include `fill`, `leading`, `trailing`, and `center`. Vertical alignment options include `fill`, `top`, `bottom`, and `center`. Both values are set to `fill` by default, which pins subviews along both of the box view's axes and ensures that there is no ambiguity regarding any subview's placement. Other values will cause subviews to be pinned to a single edge or centered along the given axis:
