On iOS 26, a Simulator screen recording shows the bottom corners of content go from rounded to square during normal push and sheet transitions. This happens on the simulator, but I don't see this on a real iPhone. Steps to reproduce: Create a new SwiftUI app and use the attached content view. Run on an iOS 26 Simulator. Start a Simulator screen recording. Tap a row to push, and tap "Filter" to present the sheet. Stop the recording and play it back frame by frame. Run the same app on a real iPhone and watch the transitions live. Question: Is this a new feature or a simulator bug?
