There was [a tweet][tweetSoto] a couple of days ago that resulted in a discussion/question about what it wrong with the usage of removedOnCompletion = NO in the [SparkRecordingCircle code][code] for that [Subjective-C post][post].

We all kept saying that the explanation doesn't fit in a tweet, so here is my rough explanation about the issues.

But, let me first say that I think that the Subjective-C articles are reallt cool and useful to learn from. This is trying to reason about the general usage of removedOnCompletion = NO, using that code as an example, since that was what was discussed on twitter.

This means that after the animation has finished, what you see on screen is not reflected in the property of the layer. The biggest issue that this can cause is that all the
