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.

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

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.

.package(url: "https://github.com/costachung/neumorphic/", .upToNextMajor(from: "1.0.0"))

Import Neumorphic package to your view.

import Neumorphic

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

RoundedRectangle(cornerRadius: 20).fill(Neumorphic.shared.mainColor()).softOuterShadow()

RoundedRectangle(cornerRadius: 20).fill(Neumorphic.shared.mainColor()).softInnerShadow(RoundedRectangle(cornerRadius: 20))

  HStack {
      Circle().fill(Neumorphic.shared.mainColor()).softOuterShadow()
      Circle().fill(Neumorphic.shared.mainColor()).softInnerShadow(Circle())
  }

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

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"))
}

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)

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)

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.
