Summary: On a UINavigationBar with prompt, when a view controller (also with prompt) is pushed, the navigation bar doesn't animate the title and back button. Steps to Reproduce: Build and run the attached sample project. Expected Results: When "Push" is tapped, the navigation bar should animate its content. When going back, the content should be animated likewise. Actual Results: Neither content is animated. Version: 11.2 Notes: When the prompt is removed, the animation works as usual. Also, a CGPostError is thrown (I've enabled a break point for that) and an error is logged: [Unknown process name] CGAffineTransformInvert: singular matrix. This worked fine in iOS 10.3.
