Sir, you've just made my day. So it's really that simple?

So, it’s a very simple almost one-to-one translation of that C code block to
Swift.You have to make sure to import CCairo at the beginning of the file, and
change the variable declarations to use let instead of the C declaration.
This works for me, as is.
import CCairo
let surface = cairo_image_surface_create(CAIRO_FORMAT_ARGB32, 240, 80)let cr =
cairo_create (surface);
cairo_select_font_face(cr, "serif", CAIRO_FONT_SLANT_NORMAL,
CAIRO_FONT_WEIGHT_BOLD)cairo_set_font_size(cr, 32.0)cairo_set_source_rgb(cr,
0.0, 0.0, 1.0)cairo_move_to(cr, 10.0, 50.0)cairo_show_text(cr, "Hello, world")
cairo_destroy(cr)cairo_surface_write_to_png(surface,
"hello.png")cairo_surface_destroy(surface)

Do so here in a few. Want a bug report for that?

Mind sending your CCairo modulemap?
I’d love to help you get this translated to Swift.

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,

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

So, if I had this code written in C:
int
main (int argc, char *argv[])
{
cairo_surface_t *surface =
cairo_image_surface_create (CAIRO_FORMAT_ARGB32, 240, 80);
cairo_t *cr =
cairo_create (surface);
cairo_select_font_face (cr, "serif", CAIRO_FONT_SLANT_NORMAL,
CAIRO_FONT_WEIGHT_BOLD);
cairo_set_font_size (cr, 32.0);
cairo_set_source_rgb (cr, 0.0, 0.0, 1.0);
cairo_move_to (cr, 10.0, 50.0);
cairo_show_text (cr, "Hello, world");
cairo_destroy (cr);
cairo_surface_write_to_png (surface, "hello.png");
cairo_surface_destroy (surface);
return 0;
}
how would I output to Swift? If I can get one or two examples, I'll be closer
to finished with using Cairo in Swift.
