Usage

Create a PDFPreviewer using the view model

import SwiftUI
import PDFPreviewer

struct ContentView: View {

    static let TestPDFURL: URL = {
        guard let pdfURL = Bundle.main.url(forResource: "Test", withExtension: "pdf") else {
            fatalError()
        }
        return pdfURL
    }()
    
    @StateObject var controller = PDFPreviewerModel()
    var body: some View {
        PDFPreviewer(model: controller)
        .task {
            await controller.loadDocument(from: Self.TestPDFURL)
        }
    }
}

Ensure the uniqueness of the view model being passed, otherwise it will result in undefined behavior.
