26. A SwiftUI List and Navigation Tutorial

A bug was introduced into iOS 13.2 that causes the example code in this tutorial to crash with the following error on returning to the main screen after adding a new car:
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', 
reason: 'Tried to pop to a view controller that doesn't exist.'
According to Apple, this is a known bug in iOS for which there is currently no workaround. It will be fixed in a future iOS release. To try out the example, create a simulator running iOS 13.1 and use it to run the app.
