'The keyWindow or contentView is missing' message before scraping #63

When testing the command line Example from the repo, this message gets printed in the console, before doing anything: The keyWindow or contentView is missing., then the script works as intended.

What does it means and how can we prevent this to show?

Are you using storyboards? If so, check if it helps to embed your viewcontroller in a navigation controller.

@fishfisher can you explain a little more please?

@avisual Are you seeing this printed to the log as well? For me the log went away when I embedded my root view controller in storyboard to a navigation controller. For me the keyWindow was nil when my main view controller was root.
