Xcode: 16.1 macOS: Sequoia When I run widget preview, I got the following errors CoreData: error: Store failed to load. <NSPersistentStoreDescription: 0x156237310> (type: SQLite, url: file:///Users/user/Library/Group%20Containers/group.com.app.name/Library/Application%20Support/default.store) with error = Error Domain=NSCocoaErrorDomain Code=256 "The file couldn’t be opened."

macOS: Sequoia Xcode: 16.1 I am working on a macOS app and it has a widget feature. When I use Swift 6 (Build Settings > Swift Language Version) in IntentExtension, the intent configuration won't show up in macOS Sequoia. If I downgrade to Swift 5, it works without any other changes. Is it a bug or am I missing something? How can I use Swift 6 with IntentExtension.

Environment Xcode: 16.1 Swift 6 and SwiftUI for macOS development macOS Sequoia I have an app for macOS, and that uses an interactive widget feature. On macOS Sequoia, the widget does not display anything and widget intent doesn't work either. I tested it on macOS Sonoma and it totally works. I assume it's a macOS bug. The app has been working fine before Sequoia. Even on Xcode, when I tried to run the widget preview, Failed to load widget. The operation couldn't be completed. (WidgetKit_Simulator.WidgetDocument.Error error 4.). I could avoid the error by changing version and build numbers, but I still got The operation couldn't be completed. (CHSErrorDomain error 1103.) How am I able to fix the issue? I wanna at least know if its a bug from the app or macOS Sequoia.

Even if there are one-many relationship models with the cascade delete rule, SwiftData does not cascade delete items. For example, there is one school has multiple students like the following models, and even when the school is deleted, the students in the school are not deleted. This happens when a user create a school and students and delete the school immediately. Are there any workarounds for now? @Model final class School { var name: String @Relationship(deleteRule: .cascade, inverse: \Student.school) var students: [Student] = [] init(name: String) { self.name = name } } @Model final class Student { var fullName: String var school: School init(fullName: String, school: School) { self.fullName = fullName self.school = school } }
