When making an init statement, it will come up with this error: Return from initializer without initializing all stored properties. What does that mean? 🤷🏻‍♂️ It would be greatly appreciated if you could give me an explanation and a solution. Thanks! 🙏 Here is the code:

@Model
class TodoList {
    var title: String

    @Relationship(deleteRule: .cascade)
    var items: [TodoItem]
    
    init(title: String) {
        self.title = title
    }
}


@Model
class TodoItem {
    var title: String
    var isDone: Bool
    
    @Relationship(deleteRule: .cascade)
    var items: [TodoItem] = []
    
    init(title: String) {
        self.title = title
    }
}

Try this:

class TodoList {
    var title: String

    @Relationship(deleteRule: .cascade)
    var items: [TodoItem] = [] // <<--
    
    init(title: String) {
        self.title = title
    }
}


@Model
class TodoItem {
    var title: String
    var isDone: Bool = false // <<--
    
    @Relationship(deleteRule: .cascade)
    var items: [TodoItem] = []
    
    init(title: String) {
        self.title = title
    }
}

It means you are not initializing all your variables in your class. Your Todolist has two variables and you only initialized one. Your Todoitem class has three variables and you initialized one variable. Change your init statements for each class to include the other variables.

    var items: [TodoItem] = [] // <<--
    
    init(title: String) {
        self.title = title
    }
}

class TodoItem {
    var title: String
    var isDone: Bool = false // <<--
    
    @Relationship(deleteRule: .cascade)
    var items: [TodoItem] = []
    
    init(title: String) {
