NeoShadow

NeoShadow is a Swift package that provides advanced shadow effects for SwiftUI shapes.

Credits

This package is a SwiftUI implementation inspired by the Beautiful Shadows Figma plugin by Alex Widua. The shadow generation algorithm and layer calculations are based on his excellent work.

Examples

NeoShadow supports two shadow styles - inner and drop shadows. Each can be fully customized using the following parameters.

Code Preview 
let shape = RoundedRectangle(
  cornerRadius: 16,
  style: .continuous
)

shape
  .fill(.white)
  .frame(width: 200, height: 200)
  .overlay {
    shape
      .neoShadow(
        style: .inner,
        color: .black,
        brightness: 0.05,
        elevation: 0.10,
        azimuth: .degrees(60),
        distance: 120,
        layerCount: 6
      )
  }
 
let shape = RoundedRectangle(
  cornerRadius: 16,
  style: .continuous
)

shape
  .fill(.white)
  .frame(width: 200, height: 200)
  .background {
    shape
      .neoShadow(
        style: .drop,
        color: .black,
        brightness: 0.10,
        elevation: 0.10,
        azimuth: .degrees(60),
        distance: 120,
        layerCount: 6
      )
  }

Parameters

  • style: Shadow style: .inner or .drop, defaults to .drop
  • color: Shadow base color, defaults to .black
  • brightness: Controls shadow intensity from 0.0 to 1.0, defaults to 0.1
  • elevation: Determines shadow depth from 0.0 to 1.0, defaults to 0.15
  • azimuth: Light source angle, defaults to .degrees(60)
  • distance: Distance from the light source to the surface, defaults to 120
  • layerCount: Number of shadow layers for depth effect, defaults to 6
