title: Playing a sound while drawing a line with Sprite Kit
body: <p>I am looking into making a drawing app with Sprite Kit in iOS, with either swift or objective C.</p>
  
  <p>There is a tutorial <a href="http://www.raywenderlich.com/80586/make-line-drawing-game-sprite-kit-swift" rel="nofollow">here</a> that shows how to draw a line with sprite kit. This is great, but for my app I want more. I want the app to play sound effects while the line is being drawn. The tone of the sound will depend on the speed at which the user is drawing the line. The faster the user moves their finger, the higher pitch the sound is. All i have found regarding playing sounds in sprite kit is background music and playing a single sound. Can someone point me in the right direction to accomplish my goal?</p>
