XCode 无法在新 iOS 系统下运行程序 configuration is unsupported running iOS which is not supported by Xcode

一、问题

The current device configuration is unsupported. This iPhone XS Max is running iOS 14.0 (18A373), which is not supported by Xcode 11.7. 也可能是：的iPhone is not available. Please reconnect the device.

• 旧版 XCode 无法再新版 iOS 系统下调试

二、解决

1. 从此链接下载 iOS 14 支持文件： filsv/iPhoneOSDeviceSupport：https://github.com/filsv/iPhoneOSDeviceSupport
2. 关闭 Xcode 将下载的文件解压缩到： /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/
3. 粘贴解压文件
4. 重新打开Xcode ，等待他 index 结束，运行解决
