The UI isn't quite right on this first patch, but it works!

iOS UI still isn't quite right, but much closer!

So close!  I need to use UIUserInterfaceSizeClass instead of hard-coding a narrow width, listen for orientation transitions, and make it scroll on iOS, but other than that it's good!  Preliminary reviews welcome.

Nit - extra spaces after the :

It's not common practice in ObjC to create a new instance of a class whose sole purpose is to be a delegate. I would've thought that the safe browsing view should be the text view delegate. Then, you wouldn't need this extra bit of plumbing when handling a click:

[((WKSafeBrowsingTextView *)textView)->_warning clickedOnLink:link];

> Source/WebKit/UIProcess/Cocoa/WKSafeBrowsingWarning.mm:456
> +    for (ViewType *subview in self.subviews) {

It seems strange to go digging around in the view hierarchy in search of a view that we created and added ourselves. Can we instead store a pointer to the WKSafeBrowsingTextView above and just invalidate its intrinsic content size here?

> Source/WebKit/UIProcess/Cocoa/WKSafeBrowsingWarning.mm:560
> +    constexpr auto noHeightConstraint = 1000000;

Perhaps CGFLOAT_MAX instead of an arbitrary large number?

Still don't understand why this doesn't follow the preference (or why you have a preference if you're not going to follow it), but OK

Why is this not in the Impl? This way it's going to make the eventual plop harder, and also means WKView doesn't get it.

And these aren't used on iOS so they can't be relevant to this patch.

> Source/WebKit/UIProcess/Cocoa/WKSafeBrowsingWarning.mm:169

Choose one space-after-colon style and stick to it (and it should be "no").
