//   How To Use Geometry Reader to Access Device Dimensions in SwiftUI
//   --------------------------------------------------------------------------------------
//   Wrap the view code you wish to measure using the GeometryReader closure.
//   Using "device" will provide the most clarity to measuring device view dimensions.
//   Access the parent view's dimensions using "device.size.width" or "device.size.height"
