Hello!

If you pass updated data to SwipeableFlatList for the first time - item at index 0 will not be updated. On second, third etc. item updated as expected.

Also if you pass updated data to SwipeableFlatList for the first time item at index higher than 0 they'll be updated as expected.

Some weird bug.

For now I just update data 2 times at one time just to be sure.

Is this a bug report?

Yes.
