# Objective - The current `EventReader::iter` has been determined to cause confusion among new Bevy users. It was suggested by @JoJoJet to rename the method to better clarify its usage. - Solves #9624 ## Solution - Rename `EventReader::iter` to `EventReader::read`. - Rename `EventReader::iter_with_id` to `EventReader::read_with_id`. - Rename `ManualEventReader::iter` to `ManualEventReader::read`. - Rename `ManualEventReader::iter_with_id` to `ManualEventReader::read_with_id`. --- ## Changelog - `EventReader::iter` has been renamed to `EventReader::read`. - `EventReader::iter_with_id` has been renamed to `EventReader::read_with_id`. - `ManualEventReader::iter` has been renamed to `ManualEventReader::read`. - `ManualEventReader::iter_with_id` has been renamed to `ManualEventReader::read_with_id`. - Deprecated `EventReader::iter` - Deprecated `EventReader::iter_with_id` - Deprecated `ManualEventReader::iter` - Deprecated `ManualEventReader::iter_with_id` ## Migration Guide - Existing usages of `EventReader::iter` and `EventReader::iter_with_id` will have to be changed to `EventReader::read` and `EventReader::read_with_id` respectively. - Existing usages of `ManualEventReader::iter` and `ManualEventReader::iter_with_id` will have to be changed to `ManualEventReader::read` and `ManualEventReader::read_with_id` respectively.
