firebase notification with xamarin forms

I've implemented firebase push notification in both android and ios,
on android it worked like a charm,
but, in ios (i am targeting ios 11.2) the following error occurd when build a release build(it worked when build a debug build)
the error is:

Native linking error: truncated fat file. Slice from 4611984 to 6449696 is past end of file with length 5144576 file '/Users/mohammadshaban/Library/Caches/Xamarin/mtbs/builds/HBRS.iOS/7757187b09de98f2bb163c41d580c1ef/obj/iPhone/AppStore/mtouch-cache/FirebaseMessaging' for architecture arm64

any ideas?

thanks in advance
