To keep the coding style consistent, I'd suggest
- replacing the
&&operator with a,like in the previous statement - remove the
== trueasshouldConfigureScrollViewInsetsis a boolean - giving this it's own line and not appending to the previous for better legibility

again, no need to check if something is not false.
My suggestion:
if presentable?.shouldHaltScroll { return }
which reads a bit easier 😉

if presentable?.shouldConfigureScrollViewInsets without the == true

Your IDE may have done this, but these whitespaces probably are deliberate and should remain in this comment 😄

Looks like your IDE filled in whitespaces for no reason here. Double check if you Xcode trims these.
Xcode -> Preferences -> Text Editing -> Editing -> While Editing -> CheckAutomatically trim trailing whitespace and Including whitespace-only lines
Summary
Currently PanModal only supports vertical scroll behavior, but there are cases where horizontal support may be needed, for example a horizontally scrolling set of images. This PR hopes to add that support to this library.
