WkWebView does not load links to pdfs

by

There are a few things you can check:

  1. Verify that the <a href links doesn’t contain target="_blank" attribute since WKWebView doesn’t know how to open the link in a new tab. see https://stackoverflow.com/a/25853806/810466 for how to work around that.

  2. Check if the link is HTTPS or update the App Transport Security Settings with the Allow Arbitrary Loads option

  3. Make sure that you start the loading request only after adding the WKWebView to the view hierarchy in didMoveToParentViewController: since it may make javascript to fail if it tries to run outside the view hierarchy

  4. Implement the WKWebView NavigationDelegate methods and make sure you return WKNavigationActionPolicyAllow when deciding the policy for the request
