'self' used before all stored properties are initialized and I have not idea why
No idea why this error occurred, and I suspect that it's me putting initialization in the wrong place. struct TodosDocument: FileDocument { var todo: Context @AppStorage("defaultText") var defaultText: String = defaultContent var content: String var erroreousFileContent: Bool = false init(content: String = defaultContent, defaultText: String = defaultContent) { self.defaultText = defaultText self.content = content do { self.todo = try JSONDecoder().decode(Context.self, from: content.data(using: .utf8)!) } catch { print("ERROR \(error)") fatalError() } } static var readableContentTypes: [UTType] { [.TodoType] } init(configuration: ReadConfiguration) throws { guard let data = configuration.file.regularFileContents, let string = String(data: data, encoding: .utf8) else { throw CocoaError(.fileReadCorruptFile) } self.content = string do { self.todo = try JSONDecoder().decode(Context.self, from: data) } catch { self.todo = try JSONDecoder().decode(Context.self, from: defaultText.data(using: .utf8)!) // <- here } } func fileWrapper(configuration: WriteConfiguration) throws -> FileWrapper { let data = content.data(using: .utf8)! let i = JSONEncoder() i.outputFormatting = .prettyPrinted let content = Context(title: todo.title, items: todo.items) do { let dat = try i.encode(content) return .init(regularFileWithContents: dat) } catch { fatalError("Cannot write content \"\(data)\" with \(configuration): \(error)") } } }

"Access to list denied" message in the run console
What I want: I'm learning developing by building a document-based todos app and just want my code to run. What I get: My app went stuck every time I open a document So I create a new project and moved all of my code there Nothing changes I think that's because I added Touch Bar support so I clear Touch Bar code off Still nothing changes, but in the LLDB console there's a message: 2022-06-06 09:17:14.098990+0800 Todos[5747:307926] [default] Failed to get state for list identifier com.apple.LSSharedFileList.ApplicationRecentDocuments Error: Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted" (Access to list denied) UserInfo={NSDebugDescription=Access to list denied} And I think there's sth to do with App Sandbox, and I added some File Access configuration. Nothing changes Then I realized I forgot to add a development team in the new project Nothing ALSO1: when I changed the Signing Certificate to Development The message in the LLDB console disappeared. I couldn't find any reference on it. ANY HELP IS GREATLY APPRECIATED!!!!!!

Sth about WWDC
I remembered there's a message that says that you cannot modify this video or whatever at the end of every session. So, if I trim the video and send it to my friend, is it allowed? Bonus: where can I find the background music for every daily debrief video (if I can)?
