API error: <_UIKBCompatInputView: 0x13fd1d7c0; frame = (0 0; 0 0); layer = <CALayer: 0x1c4426e40>> returned 0 width, assuming UIViewNoIntrinsicMetric

Question

I'm using Ionic 3 on iPhone 7 plus with iOS 11. When I run my App, and fill in some text/input fields (basic forms) the app freezes for a few seconds and becomes completely unresponsive (which isn't good, not to say the least). I noticed this error coming up in Xcode, maybe that's the problem. Has anyone else encountered similar errors?

Answer 1

Remove deprecated items from the forRoot config in app.module.ts

IonicModule.forRoot(),

Eg. remove these:

{
  scrollPadding: true,
  scrollAssist: false
}

See https://ionicframework.com/docs/utilities/config for more info.
