Xcode 15报错：找不到__ObjC模块及CocoaPods编译设置冲突

问题描述 #

执行pod install时出现以下警告：

[!] The Runner [Debug] target overrides the ENABLE_BITCODE build setting defined in `Pods/Target Support Files/Pods-Runner/Pods-Runner.debug.xcconfig'. This can lead to problems with the CocoaPods installation

• Use the $(inherited) flag, or
• Remove the build settings from the target.

[!] The Runner [Release] target overrides the ENABLE_BITCODE build setting defined in `Pods/Target Support Files/Pods-Runner/Pods-Runner.release.xcconfig'. This can lead to problems with the CocoaPods installation

• Use the $(inherited) flag, or
• Remove the build settings from the target.

[!] The Runner [Profile] target overrides the ENABLE_BITCODE build setting defined in `Pods/Target Support Files/Pods-Runner/Pods-Runner.profile.xcconfig'. This can lead to problems with the CocoaPods installation

• Use the $(inherited) flag, or
• Remove the build settings from the target.

之后真机调试时，Xcode抛出错误：no such module '__ObjC'

解决步骤 #

1. 修复CocoaPods的ENABLE_BITCODE警告

打开Xcode，选中Runner target，按以下操作处理：

• 切换到Build Settings标签页
• 在搜索框输入ENABLE_BITCODE
• 找到对应设置项，给Debug、Release、Profile三个配置的输入框都填入$(inherited)
• 保存设置后重新执行pod install，警告即可消除

2. 解决no such module '__ObjC'错误

尝试以下操作逐一排查：

• 清理编译缓存：点击菜单栏Product -> Clean Build Folder（快捷键Cmd+Shift+K）
• 删除Derived Data：打开Xcode偏好设置（Cmd+,），选择Locations，点击Derived Data旁的箭头，删除当前项目的缓存文件夹
• 检查Runner target的Build Settings里的Other Swift Flags，确保配置无误，或尝试添加-Xcc -fmodules
• 重启Xcode后重新编译项目
