# ViewCondition

✨ Super sweet syntactic sugar for SwiftUI.View initializers.

## At a Glance

```swift

struct BorderTextView: View {

  var color: Color?

  @ViewBuilder

  var body: some View {

    Text("Hello")

      .if(let: color) {

        $0.border($1)

      }

  }

}

```

This is equivalent to:

```swift

struct BorderTextView: View {

  var color: Color?

  @ViewBuilder

  var body: some View {

    let text = Text("Hello")

    if let color = color {

      text.border(color) // border doesn't allow optional

    } else {

      text

    }

  }

}

```

## Operators

### if let

```swift

let color: Color?

Text("Hello")

  .if(let: color) {

    $0.border($1)

  }

```

### if

```swift

let text = ""

Text("Hello")

  .if(text == "Hello") {

    $0.bold()

  }

```

### ifNot

```swift

let text = ""

Text("Hello")

  .ifNot(text == "Hello") {

    $0.bold()

  }

```

### then

```swift

let text = ""

Text("Hello")

  .then {

    if text == "Hello" {

      $0.bold()

    } else {

      $0.italic()

    }

  }

```

#### ⚠️ Becareful

**If you don't return view in `else`, the view may not come out.**

## Installation

Using Swift Package Manager:

```swift

import PackageDescription

let package = Package(

  name: "MyAwesomeApp",

  dependencies: [

    .package(url: "https://github.com/tokijh/ViewCondition.git", from: "1.0.0")

  ]

)

```
