Strike or Interference?

[Dakota]

Leaving your call as you made it, (no strike, no interference) my comment is that you made the explanation to the coach too complicated.

Coach: "She swung. Why was that not a strike?"
Umpire: "The ball was already in the glove. She was not attempting to hit the ball, so no strike."
Coach: "Then that was interference!"
Umpire: "Your catcher made no play, and in my judgment, the batter's swing did not interfere with your catcher."

Simple, to the point. Don't complicate things with things that didn't happen (such as CO).
