Xcode 6：编译NSManagedObject类时出现属性错误

Question

In my coreData model I have defined an entity MyEnity with several attributes. Among them two attibutes :

mute : Boolean 
deleted : Boolean

I have a NSManagedObject class associated with MyEntity . In this class I have :

@NSManaged var mute: NSNumber
@NSManaged var deleted: NSNumber // compilation error

But the second line produces an error and can't be compiled. This is the error I get :

Property 'deleted' with type 'NSNumber' cannot override a property with type 'Bool'

I don't understand what is the issue and why I don't have the same issue for the mute attribute ?

Answer 1

NSManagedObject有一个名为deleteed的属性，如下所示，因此在您的情况下使用不适当的类型（NSNumber代替Bool）使用删除的变量名将覆盖该属性，这会导致编译时错误
