Checklist

• [x] I searched for existing GitHub issues

• [x] I included all the necessary information above

Im not getting any logs in Xcode console or safari debugger.

Note: The same setup/project working fine in Cordova iOS 5.1.1 with WkWebview-Engine I'm new to cordova, so if you need any further info please let me know where can i find that info/logs.

Do i need to add anything specific in config.xml to work for WKWebview ?

I'm passing fileUrl as www folder path, is that fine?

Thanks in advance.

I'll go ahead and reopen this issue.

It looks like you're using a platform-centric workflow which is a workflow I'm not very familiar with. It may help if you share some code and xcode logs.

[perlasivakrishna]

@breautek please find the Xcode logs. cordovaLogs.txt

I have a View Controller which is superclass of "CDVViewController", Presenting controller by specifying the www folder path.

Also I observed none of the Wkwebview delgates called in CDVViewController.m.

[perlasivakrishna]

I have found the work around. Wkwebview delegates Overrided in my class.

- (void)webView:(WKWebView *)webView didFinishNavigation:(WKNavigation *)navigation {
    [webView setHidden:NO];
    [self.view bringSubviewToFront:webView];
}

so I managed to do like this. Not sure is there any better way. I have seen this piece of code where the webview is getting hided.

- (void)createGapView
{
    CGRect webViewBounds = self.view.bounds;
    webViewBounds.origin = self.view.bounds.origin;

    UIView* view = [self newCordovaViewWithFrame:webViewBounds];
    view.hidden = YES;
    view.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight);

    [self.view addSubview:view];
    [self.view sendSubviewToBack:view];
}

Also there is one more Empty view getting added to view hierarchy, not sure why it was getting added.

If i need to change anything the way I'm handling webview, please suggest me. Thanks.

The empty view is probably for the splashscreen. You might be running into https://github.com/apache/cordova-ios/issues/929

Finally found somthings same as me now, my ios build got an empty page after splash screen and without any errors. I was stuck for few days, hope someone can fix this issue.

@JayzeeHuang @perlasivakrishna Did you find any solution on this.

[JayzeeHuang]

@21pg update all to latest version, use fresh build to compare your current project, remove and readd each plugin will solve this issue.
