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 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:

http: ^0.12.0 shared_preferences: ^0.4.3 intl: any permission_handler: ^2.1.2 contacts_service: ^0.2.8 image: ^2.0.5 cached_network_image: ^1.0.0 url_launcher: ^5.0.1 path_provider: ^0.5.0+1 after_layout: ^1.0.7 connectivity: ^0.4.3+1 device_info: ^0.4.0+2 firebase_auth: ^0.11.1+7 firebase_messaging: ^5.1.2 firebase_analytics: ^5.0.0 notification_permissions: ^0.4.0 

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

The output of flutter doctor is:

Answer 1

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.

Answer 2

I have this with our Cordova app and fixed it by updating a dependency.

Are you by any chance using the dependency or an other dependency is using the dependency "cordova-plugin-inappbrowser".

If so, this should be fixed in 3.1.0. See the release notes https://github.com/apache/cordova-plugin-inappbrowser/blob/master/RELEASENOTES.md And the PR fixing it https://github.com/apache/cordova-plugin-inappbrowser/pull/271

Update: it's not fixed yet. See issue on cordova-ios: https://github.com/apache/cordova-ios/issues/661 Note the: There is no deadline, I've contacted an Apple developer that has been tweeting about moving to WKWebView to see if he can provide more information, will update if I get a response.

Update: Cordova-ios 5.1.0 seems to fix this. See https://github.com/apache/cordova-ios/pull/715
