CRED's inbuilt library for using Neumorphic components with swift

Synth

Synth is CRED's inbuilt library for using Neumorphic components in your app.

What really is Neumorphism? It's an impressionistic style, playing with light, shadow, and depth to create a digital experience inspired by the physical world. That's the definition anyway. Our recommendation is you try it out to see what you make of it. If you do create something with Synth, let us know. We're excited to see where you take it.

Installation

It can be easily integrated with Cocoapods. Add this line to your podfile:

pod 'synth-ios'

Requirements

  • iOS 11.0+
  • Swift 5.1+

Usage

Embossed and Debossed views

As it provides an extension over UIView, you can call it over any UI element

let embossedView = UIView()
embossedView.applyNeuStyle()

calling applyNeuStyle on any view will give default embossed effect. There is also a helper function getDebossModel() in NeuUIHelper which provides debossed effect.

let debossedView = UIView()
debossedView.applyNeuStyle(model: NeuUIHelper.getDebossModel())

applyNeuStyle arguments

attribute description value
model struct which lets you configure base color, shadow direction and shadow offsets NeuViewModel
showOnlyShadows enabling this will only render outer or inner shadows skipping the solid background part Bool

NeuViewModel attributes

all colors are by default derived from base color. You can explictly pass different values when needed.

attribute description value
baseColor base color based on which background and borders are rendered UIColor
bgGradientColors colors array which renders background [UIColor]
borderGradientColors colors array which renders borders [UIColor]
borderGradientWidth outer border width CGFloat
lightDirection an enum which lets define light direction NeuLightDirection
shadowType an enum which lets define shadow type, outer or inner NeuShadowType
lightShadowModel a model to customise shadow offsets of top shadow NeuShadowModel
darkShadowModel a model to customise shadow offsets of bottom shadow NeuShadowModel
blurAmount amount of guassian blur that has to be applied CGFloat
hideLightShadow hides top shadow Bool
hideDarkShadow hides bottom shadow Bool
hideBorder hides outer border Bool

Buttons

There are by default four styles which can be applied over UIButton:

elevatedSoft // an embossed button
elevatedSoftRound // a round embossed button
elevatedFlat // flat button
elevatedFlatRound // flat round button

Elevated soft button

let softButton = UIButton()
softButton.applyNeuBtnStyle(type: .elevatedSoft, title: "Idle")

Elevated soft round button

let roundButton = UIButton()
roundButton.applyNeuBtnStyle(type: .elevatedSoftRound, image: UIImage(named: "plus"))

Elevated flat button

Elevated flat button renders a flat surface on top of the elevated neumorphic platform. this flat surface can be customized in two ways:

let flatButton = UIButton()
flatButton.applyNeuBtnStyle(type: .elevatedFlat, title: "Idle")

you can also add an image aligned left to this image. synth will render a neumorphic pit on which the image is rendered.

softButton.applyNeuBtnStyle(type: .elevatedSoft, title: "Idle", image: UIImage(named: "plus"), imageDimension: 12)
softButton.applyNeuBtnStyle(type: .elevatedFlat, title: "Idle", image: UIImage(named: "plus"), imageDimension: 12)

This button is made up of three layers baseModel, innerModel and buttonContentModel named from bottom to top. NeuButtonCustomModel allows you to configure each of these layers and design button.

import Synth

let model = NeuConstants.NeuButtonCustomModel()
... some configuration
let customButton = UIButton()
customButton.applyNeuBtnStyle(customModel: model, title: "Custom Button")

This library works over base color concept and derives light and dark colors from base color itself. All views and buttons will be using this color to design neumorphic elements. This base color can be set at app start. Similarly, text attributes can be applied at an app-level to give default style to all neumorphic buttons.

NeuUtils.baseColor = UIColor.red

let textAttributes: [NSAttributedString.Key:Any] = [:]
textAttributes[.foregroundColor] = .black
NeuUtils.textAttributes = textAttributes
