Hello, and thank you for your quick reply. Workflow: I created a new project without changing any build settings. I've created two projects and uploaded them to Google Drive so build settings can be verified: https://drive.google.com/file/d/1hhnG_J005EpuViR8JLWytj5CfpyjcJfh I've also recorded two videos demonstrating the issue: The error occurs when I interact with a single text field and then go out of focus: https://youtu.be/8hJOcwhkH_Y The error occurs every time I switch between two independent text fields: https://youtu.be/C-eZUULWywA These projects are included in the Google Drive archive linked above. Additionally, the videos are available on Google Drive if that's more convenient: https://drive.google.com/drive/folders/1XpJQgfHoiEk5T_RXJiQkervhfDRUknsF?usp=sharing I am using Xcode 16 in these videos, but the issue also occurs with Xcode 15.4.
