Back swiping then dropping the gesture back where it started breaks #31471
Hello!
I climbed into the source and found the following, I hope he will help you. As it was written here #29596 (comment), this happens after a certain number of uses, but this is not what you see in the GIF, this is because if you finish scrolling on your own, the screen cannot be rejected by scrolling. I already had this error earlier and your team has already solved it #27774 , #27333

Hello!
Came here because I hit: #29596
Switched to master and it works.
About to release my app and a bit worried by this one.
Do you have any more information about the issue?
I can't reproduce it on a physical iPhone 6S.
UPDATE: start drag, don't let go, then drag all the way back. Voila! A world of pain.
but...
I can reproduce it on a iPhone X emulator.
~~@1AlexFix1 Any tip for reproducing it on a physical device?~~~
Update: see above

i was test on simulator XS, no real device
ninnepinne commentedon Apr 25, 2019
@1AlexFix1 Ahhh, sorry, false alarm/hopes...
I now understand the technique.
Start a drag and then fully drag back to original position.
Now getting the error on the physical device too... (bad words here):-(
@1AlexFix1 Thank you!
Have to go with a workaround then...

Embarrassingly the fix is one line. I'm adding more tests at the moment.

Thanks for the fast solution. Again, any clue when it’s in master 😉?
xster commentedon Apr 30, 2019
Unfortunately the PR was reverted because it made a test flaky. Will try again.
