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: Create a new SwiftUI app in Swift Playgrounds. Run the SwiftUI App Preview. 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?
