执行ionic cordova platform add iOS命令失败，尝试多方案仍无法解决

• 初始执行命令：ionic cordova platform add ios@6.2.0
• 已升级所有相关依赖，版本信息如下：

ionic - 6.17.1
npm - 7.21.1
node - 16.9.1
pod - 1.11.2

最初使用发布仅2天的最新版Xcode 13运行上述命令，输出如下：

--save flag or autosave detected
Saving ios@~6.2.0 into config.xml file ...
Update IOS build setting SWIFT_OBJC_BRIDGING_HEADER to: "$(PROJECT_DIR)/$(PROJECT_NAME)/Bridging-Header.h" for build configuration Debug
Update IOS build setting SWIFT_OBJC_BRIDGING_HEADER to: "$(PROJECT_DIR)/$(PROJECT_NAME)/Bridging-Header.h" for build configuration Release
Update IOS build setting ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES to: YES for build configuration Debug
Use Swift language version 5
Update IOS build setting SWIFT_OPTIMIZATION_LEVEL to: -Onone for build configuration Debug
Update IOS build setting ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES to: YES for build configuration Release
Use Swift language version 5
[ERROR] An error occurred while running subprocess cordova.
        
        cordova platform add ios@6.2.0 exited with exit code 1.

查阅相关公开内容后，在config.xml文件中添加如下配置：

<preference name="UseSwiftLanguageVersion" value="5" />

问题未解决。

怀疑是Xcode版本不受支持，将Xcode降级到v12.5.1，在Xcode -> Preferences -> Locations中选中该版本，随后重启所有终端、相关进程甚至Mac，问题依旧存在。

尝试执行如下命令更新CocoaPods：

pod install
pod setup

问题仍未解决。

后续执行ionic cordova prepare ios命令尝试推进流程，得到新报错：

[error] Error: Cannot find module '@ionic/angular-toolkit/package.json'

补充说明：每次更新依赖或执行命令前，都会提前删除platforms、plugins、node_modules和www文件夹，上述所有操作均未解决问题。
