Hi, Rick. The error seems to be a little better in master: <stdin>:20:11: error: cannot convert value of type 'CGPoint?' to expected argument type 'inout CGPoint' points[0].anchorPt += dv ~~~~~~~~~~^~~~~~~~
but that's still not great. So, yes, please do file a bug at bugs.swift.org <http://bugs.swift.org/>. Thank you!
