Hi,
My app is currently still using ionic 3, and I noticed a problem on the iOS version:
Whenever I tap an input field (for the first time in its view) I get a huge error log about conflicting NSLayoutConstraints and one being broken.
This apparently seems to have no side effects (everything keeps working fine). However, now I have a new page in which i run programatically “this.input.setFocus()” when user taps a button, and it is NOT working the first time. After first fail, then it works fine every other time. This of course is not nice for the user.
Also, in any scroll view, whenever this constraint is broken, the scrolling/clicking is messed up. the viewport stays as if the keyboard were still up. And you cannot click on the lower part of the screen. Sometimes it gets fixed by tapping in random places.
I know I had face a similar issue a while ago but the solution was to switch to the cordova-plugin-ionic-keyboard (https://github.com/ionic-team/cordova-plugin-ionic-keyboard/) and cordova 8.1.2 …I am still using this configuration.
This is the log:
