主键属性“名称"在对象"RealmSwiftPermissionRole"上不存在 [英] Primary key property 'name' does not exist on object 'RealmSwiftPermissionRole'

问题描述

我在我的swift项目中使用RealmSwift作为数据库.今天，在Xcode-beta版本11中打开我的项目后，我的应用因以下错误而崩溃:

I'm using RealmSwift as a database in my swift project. Today, after opening my project in Xcode-beta version 11, my app crash with this error:

由于未捕获的异常"RLMException"而终止应用程序，原因:对象"RealmSwiftPermissionRole"上不存在主键属性"名称"

Terminating app due to uncaught exception 'RLMException', reason: 'Primary key property 'name' does not exist on object 'RealmSwiftPermissionRole''

我的应用程序在Xcode(10.2.1)的早期版本上可以正常运行. RealmSwiftPermissionRole 是 Realm 中的一类，我无权访问.也许在他们的功能更新中，他们修复了此错误，但就目前而言，我进行了很多搜索，但未找到任何解决方案. (我清理了该项目，从模拟器中删除了该应用程序，然后再次运行了该项目，但未做任何更改.) 有什么建议吗?

My app works properly on the previous version of Xcode(10.2.1). RealmSwiftPermissionRole is a class from the Realm and I don't have access to it. Maybe in their feature updates, they fix this bug but for now, I search a lot but didn't find any solution. (I clean the project, delete the app from the simulator, and run the project again but nothing changed.) Any suggestion?

推荐答案

iOS 13和Xcode 11存在问题，可能会导致此问题.设置了默认String值的Realm类的所有String属性都被忽略了. 您可以通过更新到最新版本(当前为3.20.0)，然后在Xcode上解决此问题:产品->清洁生成文件夹.

There's an issue with iOS 13 and Xcode 11 which may cause this problem. All String properties of Realm classes with a default String value set are disregarded somehow. You can fix this by updating to the latest version (currently 3.20.0) and then on Xcode: Product -> Clean Build Folder.

如果您使用的是可可豆:

If you're using cocoa-pods:

打开项目的Podfile，并将RealmSwift行替换为:

Open your project's Podfile, and replace RealmSwift line with:

pod 'RealmSwift', '~> 3.20.0'

然后，打开项目文件夹中的终端，然后:

Then, open terminal on the project's folder and:

pod repo update
pod install
