Hi,
Have you been able to integrate Revealapp with a Xamarin Forms project in XS? I have added the below text to the additional options on the iOS build page, but I get a lot of linker errors, like duplication of classes.
-gcc_flags "-F/Applications/Reveal.app/Contents/SharedSupport/iOS-Libraries -all_load -ObjC -framework Reveal -framework QuartzCore -framework CFNetwork"
