Getting a popup while debugging my iOS 13 app

I am getting a popup while debugging my iOS 13 app - “kill() returned unexpected error 1”. It happens when I a testing beta version of iOS and is getting on my nerves. What might this be referring to?

Hi RowanGrey,

This is a WebKit bug and it seems that it has been fixed but not released up until the latest iOS release 13.2.2.

However you can disable/hide the logs temporarily by below method,

1- From Xcode menu open: Product > Scheme > Edit Scheme
2- On your Environment Variables set OS_ACTIVITY_MODE = disable
