I'm dealing with a strange error on Ionic's iOS native build, where I sometimes can't swipe back or switch tabs when I transition to a new page using
router.navigateByURL (. ..) and trying to troubleshoot this problem has been troublesome since I can't "see" how the gestures are handled. Does anyone know where to look in the transition management code?
Here is a video demo of the problem: https://streamable.com/hk9c0
In the video you can see me:  Swipe down to update using the item
ion-refresher and you can see the page below (already entered an error report for that section: https://github.com/ionic-team/ionic/issues/ 1
ion- fabthat appears at the bottom right because its
z indexis higher than the "fixed" page.
Currently, the best thing I have been able to do is to look at the css classes that are added to the pages, but it's not much used ….
app release is the page you can see in the video and
app-home is below the pile. It is my understanding that ionically using
hammer.js for movement, so I added it as a tag, please correct me if I'm wrong. I can't, for the life of me, consistently reproduce this error, but will often trigger 1 out of 50 attempts.
I've dug through
utils in Ionic Core to see where items are added and removed, without happiness.
I created an error message here too: https: //github.com/ionic-team/ionic/issues/18305
