How to open a Xcode 11 Beta 4 project in Xcode 10?
提问by ben_fm
I worked on a project in Xcode 11 Beta 4 and then downgraded to Xcode 10 and can't open the project.
我在 Xcode 11 Beta 4 中处理了一个项目，然后降级到 Xcode 10 并且无法打开该项目。
I want to submit my app to the app store, but I kept getting error messages in Xcode 11 beta 4. I'm a beginner and I know I tampered with the build settings trying to make it work. I deleted Xcode 11 and downloaded Xcode 10 to try and archive through that, but now I can't even open the project with Xcode 10.
我想将我的应用程序提交到应用程序商店，但我一直在 Xcode 11 beta 4 中收到错误消息。我是初学者，我知道我篡改了构建设置以使其正常工作。我删除了 Xcode 11 并下载了 Xcode 10 以尝试通过它进行存档，但现在我什至无法使用 Xcode 10 打开该项目。
I started the project on Xcode 9, I believe. I tried archiving, but there was an "SDK Version Issue", something with the old iOS. So I updated my Mac's operating system, and replaced Xcode 9 with Xcode 11 beta. That came with many more errors trying to archive, and I changed architectures and proxies and all that. So I deleted Xcode 11 and tried Xcode 10 but I can't open the project.
我相信我是在 Xcode 9 上开始这个项目的。我尝试存档，但是"SDK Version Issue"旧的 iOS有一个. 所以我更新了我的 Mac 操作系统，并用 Xcode 11 beta 替换了 Xcode 9。这带来了更多尝试存档的错误，我更改了架构和代理等等。所以我删除了 Xcode 11 并尝试了 Xcode 10，但我无法打开该项目。
It says:
它说：
"cannot be opened because it is in a future Xcode project file format. Adjust the project format using a compatible version of Xcode to allow it to be opened by this version of Xcode."
“无法打开，因为它是未来的 Xcode 项目文件格式。使用兼容版本的 Xcode 调整项目格式，使其能够被该版本的 Xcode 打开。”

You are probably getting a ton of Swift errors. The release notes for beta 4 acknowledge this is an issue.
您可能会收到大量 Swift 错误。beta 4 的发行说明承认这是一个问题。
The official workaround is to a custom build setting with the name LD_VERIFY_BITCODE, and set it to NO.
官方的解决方法是使用名称为 LD_VERIFY_BITCODE 的自定义构建设置，并将其设置为 NO。
Just remember to remove when issue is resolved!
请记住在问题解决后删除！

If problem still persists for XCode 11 beta 4, then try setting "Library Search Paths" to :
如果 XCode 11 beta 4 问题仍然存在，请尝试将“库搜索路径”设置为：
$(TOOLCHAIN_DIR)/usr/lib/swift-5.0/$(PLATFORM_NAME)
