Basically when you reach the end of the loop it crashes with that error

I can also confirm this is working fine in version 1.5.5 and not working with 1.5.7 and 1.5.8

@arribbar Can you dig into this?
I tried the examples in my laptop on IOS emulator and all the examples work fine. Even if I swipe from the edges.

It's not crashing but it doesn't work properly.

Example of a swiper with infinite loop, 3 images and 3 dots:
When you do a swipe on the left to move to the second image, the dot is not changing.
When you swipe again on the left to move to the third image, the dot is changing to position 2.
When you swipe again you are at the initial image but the dot is on position 3 instead of 1.

I revert back to 1.5.5 😢

@mtt87 Can you create a new issue please with your bug?
Can you add some infos as OS platform, RN version, RN Swiper version. If you could add an example of your code in which we can reproduce the bug, it would be great. You can fork the project and change one example to do so.
Thanks !
