title: How can I find the height and width of the safe area?
body: <p>I'm trying programmatically set constraints for some labels, buttons, and text fields relative to the height and width of the safe area. For example, I'm hoping to set the distance from the label from the top of the safe area to 10% of the safe area's height.</p>
  
  <p>How can I retrieve the height and width of the safe area? </p>
  
  <p>Is this a sound approach? My thought process was that my screen would then adjust automatically regardless of iOS device.</p>
  
  <p>Thanks for the help!</p>
