A SwiftUI component that wraps a WKWebView to display a webpage with session management, including setting cookies and injecting localStorage for session restoration.

• Loads a specified URL in a WKWebView.
• Sets cookies before loading the page to maintain session state.
• Injects localStorage items after the page loads to restore client-side data.
• Manages loading state for user feedback.

Integrate WebViewContainer into your SwiftUI view with a WebViewModel and a loading state binding.

struct ContentView: View {
 @StateObject var viewModel = WebViewModel(sessionObject: yourSessionObject)
 @State var isLoading = false
 var body: some View {
 WebViewContainer(viewModel: viewModel, isLoading: $isLoading)
 }
}

• WebViewModel: Manages the WKWebView instance and holds the SessionObject.
• SessionObject: Defines the URL, cookies, and localStorage items.

Example SessionObject:

let exampleSession = SessionObject(
 url: "https://shop.example.com/",
 cookies: [
 "session": [
 "session_id": "abc123",
 "csrf_token": "def456"
 ],
 "analytics": [
 "tracking_id": "ghi789"
 ]
 ],
 localStorage: [
 "cart": "{\"items\": [{\"id\": 1, \"name\": \"Apple\", \"quantity\": 2}]}",
 "user_preferences": "{\"theme\": \"dark\", \"language\": \"en\"}"
 ]
)

• Cookies are set with a domain from the URL and marked as secure.
• LocalStorage is injected after the page loads and the document is ready.
• Includes no error handling; consider enhancements for production.
