.xcdatamodel: cdtool cannot compile
提问by polarware
This problem occurred right after the last update of OS X El Capitan 10.11 beta 6, Xcode 7 beta 4 compiles my projects with the error in .xcdatamodel file saying:
cdtool cannot compile.
I tried to compile the same projects on OS X Yosemite and with Xcode 7.0 beta 4 I get always the same compilation error.
Any idea on how to clear this issue?
I'd appreciate any help.
这个问题发生在 OS X El Capitan 10.11 beta 6 的最后一次更新之后，Xcode 7 beta 4 编译我的项目，在 .xcdatamodel 文件中出现错误说：
cdtool cannot compile。我试图在 OS X Yosemite 上编译相同的项目，但使用 Xcode 7.0 beta 4 我总是得到相同的编译错误。关于如何解决这个问题的任何想法？我很感激任何帮助。

One solution posted on the Apple developer forums is renaming a file within the iOS Simulator.
发布在 Apple 开发者论坛上的一个解决方案是在 iOS 模拟器中重命名文件。
cd /Applications/Xcode-beta.app
cd Contents/Developer/Platforms/iPhoneSimulator.platform
cd Developer/SDKs/iPhoneSimulator.sdk/usr/lib
sudo mv dyld_sim dyld_sim.orig

This solution unfortunately did not work for me. However, I had recently changed some tables around in core data. I found the culprit by looking at all of my relationships and their inverses. One of the inverses had a dead reference. Switched it to "no inverse" did a clean and was up and running again. Hope this helps someone else.
不幸的是，这个解决方案对我不起作用。但是，我最近更改了核心数据中的一些表。我通过查看我所有的关系及其倒数找到了罪魁祸首。其中一个倒数有一个死参考。将其切换为“无反向”进行了清理并再次启动并运行。希望这对其他人有帮助。

I got this error when I changed the name of a property that was being used in a fetched property predicate. (So the predicate could no longer compile)
当我更改在获取的属性谓词中使用的属性的名称时出现此错误。（因此谓词无法再编译）
Fixing the typo in the predicate and rebuilding the project fixed the error.
修复谓词中的错字并重建项目修复了错误。

In my case, I got this error because of wrongly configured Constraints for properties. I'm not sure about what was wrong, but remove and re-add the constraints, the error disappear.
就我而言，我收到此错误是因为错误地配置了属性的约束。我不确定出了什么问题，但是删除并重新添加约束，错误消失了。
Obs: When i say constraints for properties, i'm telling about this:
Obs：当我说属性约束时，我是在说这个：
