# Objective
Contributes to #18238
Updates the `log_layers_ecs`, example to use the `children!` macro.
Note that I did not use a macro, nor `Children::spawn` for the outer
layer. Since the `EventReader` is borrowed mutably, any `.map` I did on
`events.read()` was going to have the reference outlive the function
body. I believe this scope of change is correct for the PR.
## Solution
Updates examples to use the Improved Spawning API merged in
https://github.com/bevyengine/bevy/pull/17521
## Testing
- Did you test these changes? If so, how?
- Opened the examples before and after and verified the same behavior
was observed. I did this on Ubuntu 24.04.2 LTS using `--features
wayland`.
- Are there any parts that need more testing?
- Other OS's and features can't hurt, but this is such a small change it
shouldn't be a problem.
- How can other people (reviewers) test your changes? Is there anything
specific they need to know?
- Run the examples yourself with and without these changes.
- If relevant, what platforms did you test these changes on, and are
there any important ones you can't test?
- see above
