<div>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. </div>

<div>My goal is to generate an executable that outputs *.png images using swift. </div>

<div dir="ltr">When you say, output to Swift, do you mean, call it from Swift? Return the PNG or surface to Swift?</div>
