True. I'll move them to an #else in VersionChecks.h

And fix the macOS build

On Firefox iOS, installing the custom context menu is still broken when built with XCode 10.2 beta 4.

Attempting to re-install the long press gesture recognizer after each URL change detected works in *some* cases:
https://github.com/mozilla-mobile/firefox-ios/commit/daf2a5a58e04fffc8f7b8a67e766d037ed5960bf

(It may not be clear from that diff, but that code runs on WKWebView URL change events)

Basically, if you have anything prescriptive we should be doing it would help us greatly.

I don't think there's a great solution to this problem. The existing solution already isn't great, because you're digging into WKWebView internals, which are not stable (as we saw in this bug).

The two things you want to observe are 1) any time we swap processes, and any time the WKWebView is added to the view hierarchy. I can't prescribe a solution since it's almost certainly going to involve more dirty internals, and I can't condone that! But I'm sure you can come up with something that is workable :)

I'd also recommend filing a radar requesting proper API for whatever you're trying to do, so we can get out of this business altogether.

I'll give you one hint, though: the thing you want to run after is -[WKContentViewInteraction setupInteraction]. Maybe take a peek at the callers :)

Thanks for the tips! I'll poke around and see if I can come up with a more robust hack. Being that hacks is all I have, I filed a request for official support:
