Support for altering the settings programmatically

This make sense and it should not be difficult to implement. However, I'd still like to clarify the exact usage (example), mostly to try to predict a bit further when making it.

Could you please explain the situation where this would be useful? Considering the fact that for different settings we can have different Swiper templates (entities). Thanks!

This patch will add a new hook_swiper_formatter_settings_alter

To keep consistent with phpcs and the whole codebase we should use dependency injection rather than \Drupal::moduleHandler()

I agree, here is an updated patch.

Patch files are no longer recommended, use merge requests instead → .

Added the proposed patch to MR, and fixed small coding standards.
Tested and works as expected.
