In September 2015, a breaking change in UIWebView for iOS 9 was identified, potentially causing issues for apps, particularly those using window.location semantics and Angular's $location service, leading to intermittent UI problems and console errors with infinite digest warnings. To address these issues, a patch created by the Angular team, angular-ios9-uiwebview.patch.js, was released, which should be incorporated into affected Ionic and Angular apps. Developers are encouraged to add 'ngIOS9UIWebViewPatch' to their angular modules and use version 1.1.0 or higher of the patch while a more permanent solution is being developed in collaboration with Apple and the Angular team. The patch aims to mitigate the impact of the change, and users are invited to report any ongoing issues as they work towards a lasting fix.
