Hi there,

In Xcode 12 beta 3 (12A8169g), when I load any web page in Safari on the iOS 14 Simulator, or any content in SFSafariViewController, or in the WKWebView in my app it takes about 30 seconds to load any web content.

This does not happen in Xcode 12 beta 2 (12A6163b), nor on iOS 13.6.

Looking into the details for my WKWebView I set the navigationDelegate. I retrieve my HTML content via a REST API and then try to load it via the loadHTMLString(_:baseURL:) method. The webView(_:didFinish:) on the navigationDelegate doesn't get called for 30+ seconds. It does eventually load properly if I wait long enough.

I haven't found any other posts referencing this so I'm curious if I'm doing something wrong.

Thanks!

Update: I am experiencing the same thing on Xcode 12.0 beta 4 (12A8179i) in the simulator. I had someone try it on an actual iOS 14 b3 and b4 device and they said it's working fine for them, so it seems to be a simulator-only issue. I'm still very confused why I seem to be the only one experiencing this.

I filed FB8195126 for this. Its current status is "Recent Similar Reports: Less than 10."
