manage to fix it myself:
<section class="features">
<?php
if( have_rows('features', option) ): ?>
<ul class="features__list swiper-wrapper">
<?php while( have_rows('features','option') ): the_row();
$image = get_sub_field('image');
$title = get_sub_field('title');
?>
<li class="features__item swiper-slide">
<img class="features__image" src="<?php echo $image['url']; ?>" alt="<?php echo $title; ?>"
draggable="false" />
<?php echo $title; ?>
</li>
<?php endwhile; ?>
</ul>
<?php endif; ?>
</section>
