# 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.



A note for the curious: if you wish to learn more about Synth, we have a post detailing the concept and CRED's philosophy behind it [here](https://blog.cred.club/team-cred/design/world-meet-neumorphism-open-sourcing-our-ui-framework/).

## Installation



### Cocoapods



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

```swift

pod 'synth-ios'

```



### Swift Package Manager



Follow [this doc](https://developer.apple.com/documentation/swift_packages/adding_package_dependencies_to_your_app) to add a new dependency to your project. If your `Package.swift` is already setup, add this line to project dependencies.

```swift

dependencies: [

    .package(url: "https://github.com/CRED-CLUB/synth-ios", from: "1.0.0")

],

```



## Requirements

- iOS 11.0+

- Swift 5.1+



## Usage



### Embossed and Debossed views



![Embossed and Debossed Views](https://i.imgur.com/BVirv0g.png "Embossed and Debossed Views")



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

```swift

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.



```swift

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`:

```swift

elevatedSoft // an embossed button

elevatedSoftRound // a round embossed button

elevatedFlat // flat button

elevatedFlatRound // flat round button

```



## Elevated soft button



![Elevated Soft Button](https://i.imgur.com/ih0WqFz.png "Elevated Soft Button")



```swift

let softButton = UIButton()

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

```



## Elevated soft round button



![Elevated soft round Button](https://i.imgur.com/eP17O6M.png "Elevated soft round Button")



```swift

let roundButton = UIButton()

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

```



## Elevated flat button



![Elevated Flat Button](https://i.imgur.com/tgVOK5L.png "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:

```swift

let flatButton = UIButton()

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

```



![Drawable Button](https://i.imgur.com/Bnjb5Cj.png "Drawable Button")



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

```swift

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.

```swift

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. 

```swift

NeuUtils.baseColor = UIColor.red



let textAttributes: [NSAttributedString.Key:Any] = [:]

textAttributes[.foregroundColor] = .black

NeuUtils.textAttributes = textAttributes

```



## Contributing



Pull requests are welcome! We'd love help improving this library. Feel free to browse through open issues to look for things that need work. If you have a feature request or bug, please open a new issue so we can track it.



## Contributors



Synth would not have been possible if not for the contributions made by CRED's design and frontend teams.
