I have been trying to use the WKWebView in my SwiftUI app. To do that, I created a wrapper that allows me to customize my WKWebView. This view should serve a single purpose : I need to grab an authentication token from a callback. That it why I need the last method you can find at the bottom of my CustomWebView class: import Foundation import SwiftUI import WebKit struct WebView : UIViewRepresentable {     let request: URLRequest     func makeUIView(context: Context) -> WKWebView  {         return CustomWebView().webView     }     func updateUIView(_ uiView: WKWebView, context: Context) {         uiView.load(request)     } } class CustomWebView: UIViewController, WKNavigationDelegate { // Create a custom WKWebView that supports Javascript     public let webView: WKWebView = {         let prefs = WKWebpagePreferences()         prefs.allowsContentJavaScript = true         let config = WKWebViewConfiguration()         config.defaultWebpagePreferences = prefs         let webView = WKWebView(frame: .zero, configuration: config)         return webView     }()     override func viewDidLoad() {         super.viewDidLoad()         title = "Sign In"     }     // Grab the authentication token     func webView(_ webView: WKWebView, didStartProvisionalNavigation navigation: WKNavigation!) {         guard let url = webView.url else {             return         }         // Exchange the code for the authentication access token         guard let code = URLComponents(string: url.absoluteString)?.queryItems?.first(where: { $0.name == "code" })?.value else {             return         }         print("Code: \(code)")     } } If I don't use this last method, my code runs without any error. But as soon as I run it, the callback loads correctly, but I get multiple errors in the console: 2022-06-21 16:50:17.985187+0200 MyAppsName[39758:7506939] [assertion] Error acquiring assertion: <Error Domain=RBSServiceErrorDomain Code=1 "target is not running or doesn't have entitlement com.apple.runningboard.assertions.webkit" UserInfo={NSLocalizedFailureReason=target is not running or doesn't have entitlement com.apple.runningboard.assertions.webkit}> 2022-06-21 16:50:17.985870+0200 MyAppsName[39758:7506939] [ProcessSuspension] 0x1180642a0 - ProcessAssertion: Failed to acquire RBS assertion 'ConnectionTerminationWatchdog' for process with PID=39759, error: Error Domain=RBSServiceErrorDomain Code=1 "target is not running or doesn't have entitlement com.apple.runningboard.assertions.webkit" UserInfo={NSLocalizedFailureReason=target is not running or doesn't have entitlement com.apple.runningboard.assertions.webkit} I tried to look for specific lines in "Signing & Capabilities" that could unlock any WebKit capabilities, but I can't find anything. Does anyone have a lead?
