Ionic introduced a new "Swipe to Go Back" feature during ng-conf, which enhances user navigation by allowing users to swipe from the left of a page to return to the previous one, similar to native iOS apps. This feature is exclusive to iOS within Cordova, as Android and standard mobile browsers use different methods for similar functionality. The interactive transitions replace static animations, ensuring a seamless navigation experience where views either snap back or complete the transition, mirroring the actions of the back button. The navigation's URL changes remain consistent with other lifecycle events, and further insights into the Ionic community's reception of this feature can be found in Sani Yusuf’s Medium post.
