问题描述
当在cocoapod源中使用#import语法时，我看到了与以下类似的警告，关于Pod定义的类的警告，但这是内部的Apple类定义(CLSUserDefaults)，我无法控制并且也没有子类化.
I have seen a similar warning to that below for a pod-defined class when using #import syntax in cocoapod sources, but this is an internal apple class definition (CLSUserDefaults) which I have no control over and am not subclassing.
我不知道这是否真的引起了问题，但是这不应该发生.
I don't know if this is really causing a problem, but it shouldn't be happening.
objc[22040]: Class CLSUserDefaults is implemented in both
/System/Library/PrivateFrameworks/ClassKit.framework/Versions/A/ClassKit (0x7fff9932d2c0) and
/Users/devusrid1/Library/Developer/Xcode/DerivedData/MyApp-cdokjmhxdrnhuodmhtibejxyqmqt/Build/Products/Debug/USR ID MyApp.app/Contents/MacOS/My App (0x10057f340).
One of the two will be used. Which one is undefined.
我正在使用Xcode 11
I'm using Xcode 11
推荐答案
Fabirc(或Crashlytics，取决于所使用的版本)定义了名为CLSUserDefaults的类.
Fabirc (or Crashlytics, depending on which versions used) defines a class named CLSUserDefaults.
iOS 13中的ClassKit似乎也定义了一个CLSUserDefaults类，这会导致名称冲突.
It seems that ClassKit in iOS 13 also defines a CLSUserDefaults class, which leads to a name collision.
只要您的应用代码不直接使用类CLSUserDefaults，就可以了.
It should be fine as long as your app's code not using class CLSUserDefaults directly.
