iPhone 8 iOS 11 SearchController ListView Layout Bug
After upgrading to the latest XF build (which is 188.8.131.52635 at time of writing), it looks like many of the reported iOS 11.x layout issues have been fixed. Although it seems that search wasn't part of these fixes.
When defining a SearchController on a NavigationItem on iOS 11.x, this seems to cause clipping at the bottom of the ListView that's currently on screen. I've tried calling SetNeedsLayout up the entire parent chain after setting the SearhController (as a workaround) which does *not* seem to help.
If I had to guess, I would suggest that it's to do with the '140' constant defined below as part of 2.5.0-sr1, which likely should be larger when a SearchController is defined.
I have a reproduction which you can check out below. I would also suggest testing this with different values of HidesNavigationBarDuringPresentation and HidesSearchBarWhenScrolling.
This was observed on an iPhone 8 and iPhone X running iOS 11.1.
