Is there a way to apply sound effects to collisions?

It's my first project with Swift and I'm trying to learn, but I'm stuck and can't find a solution online. Basically, it's a clone of pong, and everything is going good, until now. My problem it's that I can't understand how to make a sound effect play, once my ball hit the paddles. Everything else with the collisions is ok, and other sound like the goal one is playing fine. Just can't figure out how i can make a sound play when the two sprites collide. Here's what I've written:

func didBegin(_ contact: SKPhysicsContact) {
if contact.bodyA.node?.name == "main" && contact.bodyB.node?.name == "ball" || contact.bodyB.node?.name == "main" && contact.bodyA.node?.name == "ball" || contact.bodyA.node?.name == "enemy" && contact.bodyB.node?.name == "ball" || contact.bodyB.node?.name == "enemy" && contact.bodyA.node?.name == "ball" {
ball.run(blipPaddleSound)
}
}

It's all wrong?

I’ve already tried to break the if statement, and already tried with make one of my node run the sound effect (ball.run(‘nameofthesound’). I’ve thought maybe it could be a problem with the file, but other effect don’t play as well in that part of the code. I don’t think there is a problem with the collision, because the ball bounce on the paddle and on the wall without problem
