iOS 12 is only supported by the beta of Xcode 10 or higher.
iOS 12 仅受 Xcode 10 或更高版本的测试版支持。
If you want to use your iPhone 8 with this iOS version (NOT RECOMMENDED) with your Xcode 9.4 you can try to download the last beta of Xcode 10 and after connecting the iPhone to the mac go to this folder:
如果您想将 iPhone 8 与此 iOS 版本（不推荐）与 Xcode 9.4 一起使用，您可以尝试下载 Xcode 10 的最后一个测试版，然后将 iPhone 连接到 mac 后转到此文件夹：
/Applications/Xcode10.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
/Applications/Xcode10.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
You can see the iOS version folder of the iPhone, copy and past it to the same location in your Xcode 9.4 folder.
您可以看到 iPhone 的 iOS 版本文件夹，将其复制并粘贴到 Xcode 9.4 文件夹中的相同位置。
After this you should be able to deploy to your iPhone 8.
在此之后，您应该能够部署到您的 iPhone 8。
