Question

我有一个类UserObject（Object），它具有SessionObject（Object）的一个属性，而SessionObject具有其他Realm对象（TestObject，NewObject）的属性。当我删除子对象后，父对象成功，应用程序崩溃与错误访问：EXC_BAD_ACCESS（代码= EXC_I386_GPFLT）

class UserObject: Object{
   dynamic var uuid = ""
   dynamic var username = ""
   dynamic var session: SessionObject?

class SessionObject: Object{
    dynamic var tokenType = ""
    dynamic var refreshToken = ""
    dynamic var test: TestObject?
    dynamic var new: NewObject?
}

class TestObject: Object{
    dynamic var test = ""
}

class NewObject: Object{
   dynamic var test = ""
}


func deleteUser(){
    guard let realm = self.realmInstance else{
        return
    }
    guard let user = Array(realm.objects(UserObject.self)).first else{
        return
    }
    do{
        try realm.write {
            if let session = user.session{
                if let test = session.test{
                    realm.delete(test)
                }
                if let new = session.new{
                    realm.delete(new)
                }
                realm.delete(session)
            }
            realm.delete(user)
        }
    }catch{

    }
}

您正在运行ARC naming conventions，它适用于Swift类的NoSuchEmailException属性。目前，Realm不会生成符合ARC对特殊命名方法所期望的访问器方法，当您具有以dynamic，new或{{1开头的属性名称时，会导致对象被双重删除}}

尝试删除子对象类型的对象时，Realm崩溃
