🚀Neumorphic is a SwiftUI utility to build Neumorphism Soft UI (supports both *outer shadow and *inner shadow)

Neumorphic SwiftUI : Neumorphism Soft UI

Neumorphic is a SwiftUI utility to build Neumorphism Soft UI easily using custom view modifier and custom button style. It supports all shapes.

Hi, I’m Costa. It is simple to create outer shadow in SwiftUI by writing two lines of code. However, we can’t easily create inner shadow in SwiftUI. That’s the reason why I build this tool to make it simple and reusable.

Installation

Requirements .iOS(.v13),.macOS(.v10_15)

Swift Package Manager

  1. In Xcode, open your project and navigate to File → Swift Packages → Add Package Dependency.
  2. Paste the repository URL (https://github.com/costachung/neumorphic/) and click Next.
  3. For Rules, select version.

Swift Package

.package(url: "https://github.com/costachung/neumorphic/", .upToNextMajor(from: "1.2.0"))

Usage

Import Neumorphic package to your view.

import Neumorphic

Simply use .softOuterShadow and .softInnerShadow methods to create outer shadow and inner shadow respectively.

Create Rounded Rectangle with Outer Shadow

Neumorphic SwiftUI Outer Shadow

RoundedRectangle(cornerRadius: 20).fill(Color.Neumorphic.main).softOuterShadow()

Create Rounded Rectangle with Inner Shadow

Neumorphic SwiftUI Inner Shadow

RoundedRectangle(cornerRadius: 20).fill(Color.Neumorphic.main).softInnerShadow(RoundedRectangle(cornerRadius: 20))

Create Circles

Neumorphic SwiftUI Circles

  HStack {
      Circle().fill(Color.Neumorphic.main).softOuterShadow()
      Circle().fill(Color.Neumorphic.main).softInnerShadow(Circle())
  }

Create Soft Button

Neumorphic SwiftUI Button

Button(action: {}) {
    Text("Soft Button").fontWeight(.bold)
}
.softButtonStyle(RoundedRectangle(cornerRadius: 20))

Create Soft Button with custom style

Neumorphic SwiftUI Button

HStack {
    Button(action: {}) {
        Image(systemName: "heart.fill")
    }.softButtonStyle(Circle())

    Button(action: {}) {
        Image(systemName: "heart.fill")
    }.softButtonStyle(Circle(), mainColor: Color.red, textColor: Color.white, darkShadowColor: Color(rgb: 0x993333, alpha: 1), lightShadowColor:Color("redButtonLightShadow"))
}

Customization

softInnerShadow

You can change the color, spread of the shadow, and the shadow radius of the inner shadow.

softInnerShadow<S : Shape>(_ content: S, darkShadow: Color, lightShadow: Color, spread: CGFloat, radius: CGFloat)

softOuterShadow

You can change the color, offset of the shadow, and the shadow radius of the outer shadow.

softOuterShadow(darkShadow: Color, lightShadow: Color, offset: CGFloat, radius:CGFloat)

Neumorphic SwiftUI Search bar

Example of using background method to add it under TextField:

            VStack {
                HStack {
                    Image(systemName: "magnifyingglass").foregroundColor(secondaryColor).font(Font.body.weight(.bold))
                    TextField("Search ...", text: $name).foregroundColor(secondaryColor)
                }
                .padding()
                .background(
                    RoundedRectangle(cornerRadius: 30).fill(mainColor)
                    .softInnerShadow(RoundedRectangle(cornerRadius: 30), darkShadow: darkShadowColor, lightShadow: lightShadowColor, spread: 0.05, radius: 2)
                )
            }
            .padding()

Or, something like this:

Neumorphic SwiftUI bar chart

ZStack(alignment: .bottom){
                RoundedRectangle(cornerRadius: 20).fill(mainColor)
                .softInnerShadow(RoundedRectangle(cornerRadius: 20), darkShadow: darkShadow, lightShadow: lightShadow, spread: 0.3, radius: 2)
                .frame(width: 30, height:150)
                
                RoundedRectangle(cornerRadius: 20).fill(barColor)
                    .frame(width: 30, height:100)
            }

Soft Button Style Customization

softButtonStyle<S : Shape>(_ content: S, padding: CGFloat, mainColor: Color, textColor: Color, darkShadowColor: Color, lightShadowColor: Color, pressedEffect: SoftButtonPressedEffect)

Soft Button - Pressed Effects

                        Spacer()
                        Button(action: {}) {
                            Text(".none").fontWeight(.bold)
                        }.softButtonStyle(Capsule(), pressedEffect: .none)
                        Spacer()
                        Button(action: {}) {
                            Text(".flat").fontWeight(.bold)
                        }.softButtonStyle(Capsule(), pressedEffect: .flat)
                        Spacer()
                        Button(action: {}) {
                            Text(".hard").fontWeight(.bold)
                        }.softButtonStyle(Capsule(), pressedEffect: .hard)
                        Spacer()
                    }

For example, Play and Stop Button

    Toggle(isOn: $toggleIsOn, label: {
        if toggleIsOn {
            Image(systemName: "stop.fill")
                .font(.title)
        }
        else{
            Image(systemName: "play.fill")
                .font(.title)
        }
    })
    .softToggleStyle(Circle(), padding: 20)

Auto, Light, and Dark Mode for iOS and MacOS

Default Neumorphic Colors

Access default neumorphic colors using Color.Neumorphic, for example,

Color.Neumorphic.main

Auto ColorScheme

  • Color.Neumorphic supports light and dark mode on both iOS and MacOS automatically by default.

Set the color scheme manually

  • When you use default neumorphic colors and you want to set the color scheme manually, you can do it by setting Color.Neumorphic.colorSchemeType to the type you want. For example, to force the color scheme in dark mode, use:
Color.Neumorphic.colorSchemeType = .dark
