[swift-users] Need Help with C-to-Swift (finally)

I want to call PNG surfaces from Swift, as well as use cairo_line_to() and cairo_move_to() in Swift. Thing is, I need an example of cairo used in Swift so I can apply it to the rest of cairo.
My goal is to generate an executable that outputs *.png images using swift.
Thanks for the support,--MGage--

When you say, output to Swift, do you mean, call it from Swift? Return the
PNG or surface to Swift?
