Xcode 14兼容旧设备iOS9.0 - iOS11

在Xcode升级到Xcode14以后，大家都发现系统的支持版本升级到了11.0，那么想要调试11.0之前的系统该怎么办呢

1.首先在Xcode14之前的版本下，应用程序 Xcode 显示包内容 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport ，把程序中的低于11.0的文件夹拷贝到Xcode14的相应目录下。

2.在Xcode14下，应用程序 Xcode 显示包内容 修改以下文件,记得修改前备份,防止改错无法还原.

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/SDKSettings.plist

添加 9.0-10.3 的版本 到以下节点中

SupportedTargets - iphoneos - ValidDeploymentTargets

DefaultProperties - DEPLOYMENT_TARGET_SUGGESTED_VALUES

如果没有包含，请把这个plist文件拷贝到桌面手动添加。添加完成后再粘贴到原来的位置。重启Xcode即可。

3.MinimumDeploymentTarget 改为9.0。（在SDKSettings.plist文件中搜MinimumDeploymentTarget）

配置文件拖出来到桌面 修改,完了覆盖进去
