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.
  4. Click Finish.

Swift Package

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

Usage

Import Neumorphic package to your view.

import Neumorphic
Swift

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()
Swift

Create Rounded Rectangle with Inner Shadow

Neumorphic SwiftUI Inner Shadow

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

Create Circles

Neumorphic SwiftUI Circles

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

Create Soft Button

Neumorphic SwiftUI Button

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

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"))
}
Swift

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)
Swift

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)
Swift

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()
Swift

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)
            }
Swift

Example Project

Check out the neumorphic-ios-example XCode project to see how to build neumorphic UI and buttons. If you use the default shadow colors of Neumorphic, you can also get dark mode support for free.

Soft Button Style Customization

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

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()
                    }
Swift

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)
