If the black hole formed while in the system, the resulting radiation would wipe out all life in a light year radius. If the black hole captured the star, the tidal forces would slowly rip the planets apart.

More likely than "swallowing the planet" is disrupting orbits, sending the planet either flying off into deep dark cold space or onto some uninhabitable orbit around the star.

If the person above did their math correctly, a black hole and a star orbiting each other a 1.39 AU would be a problem for planets. Injecting a black hole like that into our solar system would be real trouble for Mercury, Venus, Earth, Mars, probably Jupiter, and Saturn too. The rest might be ok after a long while for their orbits to stabilize.

The orbital period is 185 days so it might be quite close to the black hole.
