On scrolling screen freezes in iOS. (Xcode "Thread 1: signal SIGABRT" exception)

[surendharreddy]

I'm using this module in my app. Module works fine for Android but I've an issue with iOS.

Issue is the screen freezes whenever I try to scroll the view. Xcode throws an error Thread 1: signal SIGABRT exception. Help me figure it out.

Module version: "react-native-directed-scrollview": "^1.3.1" React Native version: "react-native": "^0.51.0"

Let me know if any extra details are required.

Share my xcode logs here.

I'm unable to repro this using the above versions. Did you follow the usage example here?

@alexlevy0 Fixed in 1.3.6

[stokesbga]

Im still getting this on 1.3.6 only with vertical scroll. I tried to reproduce the example, but both scroll does not work - only horizontal. When a vertical scroll is by itself, then crash happens.

HELP !!!! :((((
