Folks, this is killing me! All I want to do is make a "pulsing dots" loading animation, a la iOS "other person is typing" in Messages. I'm creating three dots with a for loop, and putting them into an array. But for the life of me, I can't figure out how to target these individual layers. My newbie approach was going to be to create three separate animations for each dot created... if anyone has a better method, I'd love to hear it!
