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

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

ITMS-90809: Deprecated API Usage - Apple will stop accepting submissions of apps that use UIWebView APIs . See https://developer.apple.com/documentation/uikit/uiwebview for more information.

Since I'm not using the webview plugin I'm at a loss as to where the UIWebView API is being used. Any advice on how to solve this?

This error appears with the latest stable flutter build 1.7.8+hotfix.4 and with the following packages included:

All of the packages have been updated to their latest version.

Solution

  • I think it was being used from the firebase_auth plugin. Try to update it to its latest version and then remember run pod update.
