Issue

Tests using Safari, ReactNative, or Native Apps may experience fatal errors if they're relying on the outdated Apple API UIWebView.

 

Details

iOS 14.5 removed support for the deprecated API “UIWebView”. Any users who are testing apps which rely on this, will see their tests fail. This applies to anything which calls the UIWebView API. Any Safari web tests or Native tests (including ReactNative apps) that rely on WebViews could be impacted. Xcode will warn the developer about any WebViews leveraging the UIWebView api.

This API was first marked as deprecated in iOS 12.0 

 

Deprecated UIWebView API:

Replacement WKWebView API:

Resolution

Replace any usage of the UIWebView API with WKWebView. Continue your testing on iOS 14.4 and below in the interim.
