Documentation

Load images using ImagePipeline from the lean core Nuke module:

func loadImage() async throws {
    let imageTask = ImagePipeline.shared.imageTask(with: url)
    for await progress in imageTask.progress {
        // Update progress
    }
    imageView.image = try await imageTask.image
}

Or use the built-in UI components from NukeUI:

struct ContentView: View {
    var body: some View {
        LazyImage(url: URL(string: "https://example.com/image.jpeg"))
    }
}

The Getting Started guide is the best place to start. Check out Nuke Demo for more examples.

The package ships with four modules that you can install depending on your needs:
