        Has anyone else experienced this issue?


        Any popover that contains a WebKit View crashes the extension in Catalina Beta 1-3 and Safari 13. This seems like an upstream bug, so I've filed a bug report in Beta 1, but never got any response from Apple.


        If anyone has advice on dealing with this, it would be much appreciated. This not only affects existing extensions but any new ones as well.

          What was your feedback ID number?

            Have same issue after update to macOS Catalina 10.15.

            How do you fixed this?

              I had never recieved an email alerting me to the follow ups on this thread. Here's answers to both the followups:




              I filed two reports. The first report was filed under "Developer Tools". The id for that is: FB6140383 - I thought that, perhaps, that was not the proper category, so I later filed it under, "macOS" with an id of: FB6162986


              I have since worked around this issue, which I will explain below.

              The workaround I used was simply creating the webview programatically rather than through the UI Builder. In fact, I stopped interacting with the UI Builder all together because just dragging a WebKit View (and subsequently doing nothing with it afterwards) caused all my extension tests to crash.


              I am unsure if this bug still exists.
