Unused Components - Are these a memory concern?

Questions & Answers
1

I’m building an app for iOS.
It’s therefore essential that I watch the app’s memory consumption.

I just added a new camera to the scene, allowing the user to switch between the two.
For the second camera, there’s no GUI, or Flares. A stock camera comes prepackaged with a GUILayer component and a Flare Layer component.

Should I look out for these unused components and remove them as necessary, or do they not impact the memory consumption?

No, but unused components are bad feng shui. Remove them so as to give your project better energy flow.
