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?
Configuration:
- Xcode 26.4.1
- iOS 26 Simulator — iPhone 17 Pro
- Real device: iPhone 16 Pro Max
