I’m looking for the most straight-forward way to get the FULL html from a page. After page load and after JS will finish work.

Speed is not important. Optimization is not important. Locking of main thread is not important.

Only the result is important: get the full HTML code of the page. Synchronously.

I’m tried to get html with WKWebView:

class InternetLoader {
    private let webView = WKWebView(frame: .zero)
    
    private let script = """
    window.onload = function() {
        document.body.innerHTML;
    };
    """
    
    private var resultHtml: String? = nil
    
    func getHTML(from url: URL) -> String {
        webView.load(URLRequest(url: url))
        
        let semaphore = DispatchSemaphore(value: 0)
        
        webView.evaluateJavaScript(script) { (result, error) in
            if let error = error {
                print("Error executing JavaScript: (error.localizedDescription)")
            } else if let htmlContent = result as? String {
                self.resultHtml = htmlContent
            }
            
            semaphore.signal()
        }
        
        semaphore.wait()
        
        return resultHtml!
    }
}

Usage:

let il = InternetLoader()
let html = il.getHTML(from: URL(string: "/questions"))

But it endlessly stuck.

what I’m doing wrong?
