Prepare the swordfish: rinse and pat dry. Remove the strip of skin and cut into 1-inch cubes.
Prepare other ingredients: cut the cherry tomatoes in half; remove the olive pits and roughly chop the olives.
Bring a large pot of salted water to a boil while you begin cooking the sauce.
Heat olive oil over medium heat in a skillet large enough to hold the cooked pasta. Add the swordfish, salt and pepper, to taste, and cook for 2 minutes.
Pour in the white wine and cook, scraping the bottom of the pan with a wooden spoon to incorporate any pieces of swordfish, for 2 minutes in order to allow the wine to evaporate. Transfer the swordfish to a plate and set aside.
Add minced garlic to the pan and cook for 30 seconds. Add the cherry tomatoes, a pinch of salt and cook, stirring occasionally, for 5 minutes.
At this point add pasta to the boiling pot of water and cook for 2 minutes less than suggested on the package.
Stir the capers and olives into the skillet with the cherry tomatoes and cook for 2 minutes. Return the cooked swordfish to the pan, stir into the sauce and cook for 1 minute.
Drain the pasta and add to the pan with the sauce. Stir to combine all ingredients. If needed, add a ladle of pasta cooking water to the pan to loosen the sauce as well as help the sauce adhere to the pasta.
Remove from the heat, drizzle with a little extra olive oil and top with freshly chopped parsley before serving.
