Swift Playgrounds macOS repeatedly asks “My App would like to access data from other apps”

Environment:

• Swift Playgrounds (macOS)
• SwiftUI App Preview
• macOS version: 26.2 (25C56)

Issue: In Swift Playgrounds on macOS, the app repeatedly shows the system permission dialog:

“My App would like to access data from other apps. Keeping app data separate makes it easier to manage your privacy and security.”

Steps to Reproduce:

1. Create a new SwiftUI app in Swift Playgrounds.
2. Run the SwiftUI App Preview.
3. When the permission dialog appears, click “Allow”.

Expected Result: The permission should be granted once and persist, allowing the preview to continue normally.

Actual Result: After clicking “Allow”, the SwiftUI App Preview crashes and restarts. When the preview restarts, the same permission dialog appears again. This repeats indefinitely, creating a loop.

Notes:

• This occurs even when no explicit file system or inter-app data access code is written.
• The permission choice does not appear to persist between preview restarts.

Question: Is this a known limitation of Swift Playgrounds sandboxing or SwiftUI App Preview? Is there an official workaround or recommended approach to avoid this behavior while using Swift Playgrounds?
