Xcode13开发CoreData Demo点击TextField出现_PointQueue类重复报错如何解决？

问题说明 #

该警告为Xcode13搭配iOS15模拟器的已知系统级框架冲突，是苹果官方私有框架UIKitCore和TextInputUI重复定义内部类导致，和开发者编写的CoreData业务代码无关联，不会触发线上崩溃，仅会在模拟器调试阶段产生日志干扰。
触发警告的日志如下：

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.

解决方法 #

• 升级Xcode版本：该问题在Xcode14及后续版本已被官方修复，升级后使用对应版本的iOS模拟器运行即可完全消除该警告。
• 临时屏蔽控制台警告：如果暂时不想升级Xcode，可通过Scheme配置过滤日志：
  1. 打开Xcode项目，依次点击顶部菜单栏 Product → Scheme → Edit Scheme
  2. 左侧选择Run选项，切换到Arguments标签页
  3. 在Environment Variables栏添加变量，名称填OBJC_DISABLE_NONPOINTER_ISA，值填YES，保存后重新运行项目即可
• 更换低版本模拟器：选择iOS14及更低版本的模拟器运行项目，不会触发该框架冲突警告。

注意事项 #

该警告仅存在于iOS15 + Xcode13的模拟器运行环境，不影响真机运行效果，也不会导致App Store审核被拒或线上崩溃，无需调整业务代码逻辑。
