# PublisherView

[![Latest release][release shield]][releases] [![Swift 5.1][swift shield]][swift] ![Platforms: iOS, macOS, tvOS, watchOS][platforms shield]

A SwiftUI view that subscribes to a Combine publisher to show different views for values and failures.

## Usage

This can be used with a data task publisher which then decodes the data into model objects. In this example We display a list of posts when they are received or show the error message on screen if the task fails.

```swift

struct PostsView: View {

  // Get this publisher from somewhere, maybe a data task publisher

  let publisher: AnyPublisher<[Post], Error>

  var body: some View {

    PublisherView(publisher: publisher,

                  initial: LoadingView.init,

                  output: Content.init,

                  failure: FailureView.init)

  }

}

extension PostsView {

  fileprivate struct Content: View {

    let posts: [Post]

    var body: some View {

      List(posts) { post in

        Text(post.title)

      }

    }

  }

}

struct LoadingView: View {

  var body: some View {

    // Some awesome loading view

  }

}

struct FailureView: View {

  let error: Error

  var body: some View {

    Text(error.localizedDescription)

  }

}

```
