I'm looking for a free interactive or CLI tool to convert SVG files to vector PDF running on a Mac. The goal is to use the resulting files in Xcode image assets.
Inkscape should do nicely.
inkscape input.svg --export-pdf=output.pdf
Alternatives may be
convert from ImageMagick (although I am not sure this preserves the figure as a vector graphic) or
rsvg-convert from librsvg. (On how to install the latter on Mac, see this Stackoverflow question and answers.)
