Support for iOS' voice over mode is broken

Which OS ?

iOS

Version

Which versions are you using:

• react-native-swiper v1.5.13
• react-native v0.57.4

Expected behavior

Voice over mode in iOS is used by people with disabilities (e.g. blind people or people with poor eye sight) to read out elements and text inside apps.

When iOS' voice over mode is used it should be possible to use the scrolling gesture to navigate the slides by changing from one slide to another after a text has been selected.

Actual behaviour

The voice over mode scrolling is not working properly. It gets stuck between pages and only partly moves to the correct slide. It is possible to navigate the slides with prev and next buttons, but that is not very easy for blind users.

How to reproduce it>

To help us, please fork this component, modify one example in examples folder to reproduce your issue and include link here.

• https://github.com/leecade/react-native-swiper/tree/master/examples/components/Basic

Steps to reproduce

1. Turn on iOS voice over mode
2. Try navigating between slides in any of the examples in this repo

Start with the example at examples/components/Basic and reproduce the issue using iOS VoiceOver while navigating slides with the scrolling gesture. Trace the swiper behavior used by that example and verify that VoiceOver scrolling moves cleanly between complete slides rather than getting stuck or partially advancing.
