ios – SCORM lesson standing is “In Progress” even after full the studying of lesson

We now have SCORM lesson characteristic in our iOS cell app. We open the SCORM lesson in WKWebView with the next code:

WKWebViewConfiguration *configuration = [[WKWebViewConfiguration alloc] init];
    if([[NSUserDefaults standardUserDefaults] objectForKey:[TMEUserDefaultKeys cdnSetCookie]]) {
        WKUserContentController *userContentController = [[WKUserContentController alloc] init];
        [userContentController addScriptMessageHandler:self name:@"callNativeAction"];
        [userContentController addScriptMessageHandler:self name:@"callNativeActionWithArgs"];
        WKUserScript *cookieScript = [[WKUserScript alloc]
              initWithSource:[NSString
                                 stringWithFormat:@"document.cookie="%@";",
                                                  [[NSUserDefaults standardUserDefaults] objectForKey:[TMEUserDefaultKeys cdnSetCookie]]]
               injectionTime:WKUserScriptInjectionTimeAtDocumentStart
            forMainFrameOnly:YES];
        [userContentController addUserScript:cookieScript];
        [configuration setUserContentController:userContentController];
    }
    
    WKPreferences *preferences = [[WKPreferences alloc] init];
    preferences.javaScriptEnabled = YES;
    preferences.javaScriptCanOpenWindowsAutomatically = YES;
    configuration.preferences = preferences;
    configuration.websiteDataStore = [WKWebsiteDataStore defaultDataStore];
    configuration.allowsInlineMediaPlayback = YES;
    configuration.allowsAirPlayForMediaPlayback = YES;
    configuration.allowsPictureInPictureMediaPlayback = YES;
    configuration.mediaTypesRequiringUserActionForPlayback = WKAudiovisualMediaTypeNone; //WKAudiovisualMediaTypeNone;
    NSArray<NSHTTPCookie *> *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];
    for(NSHTTPCookie *cookie in cookies) {
        [configuration.websiteDataStore.httpCookieStore setCookie:cookie completionHandler:nil];
    }

    self.webView = [[WKWebView alloc] initWithFrame:self.view.bounds configuration:configuration];
    self.webView.UIDelegate = self;
    self.webView.navigationDelegate = self;
    self.webView.allowsLinkPreview = YES;
    self.webView.translatesAutoresizingMaskIntoConstraints = false;
    self.webView.scrollView.bounces = NO;
    self.webView.scrollView.showsVerticalScrollIndicator = NO;
    self.webView.allowsBackForwardNavigationGestures = YES;
    self.webView.contentMode = UIViewContentModeScaleAspectFit;
    
    UISwipeGestureRecognizer *swipeUp = [[UISwipeGestureRecognizer alloc] initWithTarget:self motion:@selector(setNavigationBarWithGestureRecognizer:)];
    UISwipeGestureRecognizer *swipeDown = [[UISwipeGestureRecognizer alloc] initWithTarget:self motion:@selector(setNavigationBarWithGestureRecognizer:)];
    swipeUp.delegate = self;
    swipeDown.delegate = self;
    // Setting the swipe route.
    [swipeUp setDirection:UISwipeGestureRecognizerDirectionUp];
    [swipeDown setDirection:UISwipeGestureRecognizerDirectionDown];
    [self.webView addGestureRecognizer:swipeUp];
    [self.webView addGestureRecognizer:swipeDown];
     
    [self.view addSubview:self.webView];

Even after we full the studying of lesson, whereas we fetch the standing of the lesson, it returns In Progress.

Thanks prematurely.
