Network Connection Lost When Serving from SwiftUI View
I'm interested in serving a single page website as local files within my iOS app. I'm using swifter's shareFilesFromDirectory method to serve a number of HTML, JavaScript, CSS, images, and audio files successfully. However, I often (but not always) get a "Failed to load resource: The network connection was lost." in the WKWebView console on various assets.
And this is the code for my view:
import WebKit
import SwiftUI
import Swifter
struct WebView: UIViewRepresentable {
var url: String
var server = HttpServer()
var directories = [
"styles", "third-party", "src", "images",
"assets/A", "assets/B", "assets/C", "assets/D",
"assets/E", "assets/F", "assets/G", "assets"
]
func makeUIView(context: Context) -> WKWebView {
let path = Bundle.main.bundlePath
directories.forEach { (dir) in
server["/\(dir)/:path"] = shareFilesFromDirectory("\(path)/www/\(dir)/")
}
server["/:path"] = shareFilesFromDirectory("\(path)/www")
do {
try server.start(8080)
} catch {
print("Failed to start local server.")
}
let view = WKWebView()
let url = URL(string: "http://localhost:8080/index.html")!
let request = URLRequest(url: url)
view.allowsBackForwardNavigationGestures = false
view.scrollView.contentInsetAdjustmentBehavior = .never
//view.configuration = WKWebViewConfiguration
view.load(request)
return view
}
func updateUIView(_ uiView: WKWebView, context: UIViewRepresentableContext<WebView>) {
}
}
With an idea of what the project structure looks like here:
Lastly, from the Podfile it looks like I'm using 1.5.0. Is there a way to configure the server to handle more throughput? Or a more efficient way to serve the contents of a directory recursively?
