_Mattt's_ beautiful gist to gain SwiftUI previews for your UIViews turned into Swift Package.

# UIViewPreview Swift Package

Swift Package contains:

* `UIViewPreview`

* `UIViewControllerPreview`

Please read more about the use-cases for `UIViewPreview` in the `NSHipster` blogpost:

[https://nshipster.com/swiftui-previews/](https://nshipster.com/swiftui-previews/)

## Requirements:

* macOS Catalina

* Xcode 11.0 and above

* Swift 5.1 and above

* iOS 13.0 and above

* tvOS 13.0 and above

## Installation

### Swift Package Manager

Add

`.package(url: "https://github.com/bielikb/UIViewPreview.git", from: "1.0.0")`

to your `Package.swift` file's `dependencies`.

If youre using Xcode 11.0 add `UIViewPreview` Swift Package to your target(s) using Xcode.

## PreviewProvider (Official Apple Docs)

```

/// Produces view previews in Xcode.

///

/// Xcode statically discovers types that conform to `PreviewProvider` and

/// generates previews in the canvas for each provider it discovers.

@available(iOS 13.0, OSX 10.15, tvOS 13.0, watchOS 6.0, *)

public protocol PreviewProvider : _PreviewProvider

```

## Example:

```

import UIViewPreview

#if canImport(SwiftUI) && DEBUG

import SwiftUI

@available(iOS 13.0, *)

struct Label_Preview: PreviewProvider {

    static var previews: some View {

        UIViewPreview {

            let label = UILabel()

            label.frame = CGRect(origin: .zero,

                                 size: CGSize(width: 100, height: 100))

            label.text = "Text previewed in SwiftUI Preview"

            return label

        }

    }

}

#endif

```
