Flutter: How to fix ITMS-90809: Deprecated API Usage - Apple will stop accepting submissions of apps that use UIWebView APIs

Question

When submitting my latest build, Apple suddenly returned a message saying that there was an issue, specifically:

ITMS-90809: Deprecated API Usage - Apple

Answer 1

Since this has become the "goto answer" on Google for this rejection message, I'll add a React Native fix.

On React Native, considering that you've been a good developer and are not using UIWebView in your own code, use the following command to find out which of your dependencies still does use UIWebView:

grep -r UIWebView node_modules/*

There is a bit more info here.
