ios - 当我单击文本字段时，两个都实现了类 _PointQueue ...我该如何解决这个问题？

Question

我正在使用 xcode 13 并在 coredata 上进行演示。

objc[6188]: Class _PathPoint is implemented in both/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/System/Library/PrivateFrameworks/UIKitCore.framework/UIKitCore(0x114a8fa78) and/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/System/Library/PrivateFrameworks/TextInputUI.framework/TextInputUI(0x12cd4a8b0). One of the two will be used. Which one is undefined.

This is not an error per se. Rather, it’s the Objective-C runtime telling you that:

• Two frameworks within your process implement the same class (well, in this case classes, namely _PathPoint and _PointQueue).
• The runtime will use one of them, choosing it in an unspecified way.

This can be bad but in this case it’s not. Both of the implementations are coming from the system (well, the simulated system) and thus you’d expect them to be in sync and thus it doesn’t matter which one the runtime uses.

So, in this specific case, these log messages are just log noise.
