SwiftDataPersistentModel.swft：540：致命错误：不支持的关系密钥路径ReferenceWritableKeyPath

我有一对多关系SwiftData模型.然而，当我试图追加数据时，会导致错误SwiftData/PersistentModel.swift:540: Fatal error: Unsupported relationship key path ReferenceWritableKeyPath<Student, School>.我应该如何解决这个问题？

@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
  }
}

struct AddStudentToSchoolView: View {
  let school: School
  @Environment(\.modelContext) private var modelContext

  var body: some View {
    // code ...
    Button("submit". action: { addStudentToSchool() })
  }
  
  private func addStudentToSchool() {
    let student = Student(fullName: "Jenny", school: self.school)
    modelContext.insert(student)
    self.school.students.append(student) // <- error SwiftData/PersistentModel.swift:540: Fatal error: Unsupported relationship key path ReferenceWritableKeyPath<Student, School>
  }
}

如果我注释掉self.school.students.append(student)行，它工作得很好，但即使我删除了一所学校，属于该学校的学生也不会像级联删除一样被删除.我在苹果https://developer.apple.com/forums/thread/736908论坛上发现了类似的问题
