I suppose my initial “anyone has ideas” was because the WebKit folks duped
it to a radar which I thought was odd, maybe it isn’t. Maybe someone else
will find this useful too.
As you and Jens noted working around it for my case is easy but I don’t see
anything in the WebKit API that says that the WebPolicyDelegate callbacks
will be called on the main thread. So if that changes then my workaround
breaks because I introduced code that makes assumptions. I have mitigated
this by adding assets that will cause my code to crash immediately if I
tell WebKit to download on anything other than the main thread.
Cheers,
Nick
