创建NSManagedObject子类...在我的项目中犯一个新错误 [英] Create NSManagedObject Subclass... make a new Error in my project

问题描述

我想通过Editor\Create NSManagedObject Subclass ...菜单为我的实体添加一个类。但是当我添加它时，项目出错了，这是消息：

i want to add a class for my entity by Editor\Create NSManagedObject Subclass... menu . but when i added it , the project made an error , this is the message:

Multiple commands produce '/Users/mohsenkhodadadzadeh/Library/Developer/Xcode/DerivedData/walk-fcnteanemrfigmfaalqkvwigvwqc/Build/Intermediates.noindex/walk.build/Debug-iphonesimulator/walk.build/Objects-normal/x86_64/WalkEntity+CoreDataProperties.o':

我更改了构建系统文件->项目设置中的旧版构建系统。但这还行不通

i changed that build system to Legacy Build system in File->Project settings . but it diden't work yet

该项目是用xcode9制作的，我现在用xcode 10进行了开发

this project made with xcode9 and i develope it with xcode 10 now

推荐答案

在项目导航器中选择 xcdatamodeld 文件，选择实体并按⌥⌘3（数据模型检查器）。

Select the xcdatamodeld file in the project navigator, select the entity and press ⌥⌘3 (Data Model Inspector).

如果您手动创建了该类，则必须将 Codegen 弹出窗口设置为手动/无，否则将隐式创建类文件。

If you created the class manually the Codegen popup must be set to Manual/None otherwise the class file is created implicitly.
