Xcode 8 个 UITests "direct field offset" 的构建错误

Question

我遇到了一组神秘的链接器错误。我的常规目标和 UITest 目标可以正常构建和执行，但 UnitTest 目标总是失败并出现以下错误。似乎是 CoreData 的某种问题，但我无法弄清楚为什么它在测试目标上出错而不是在主要目标上出错。我试过了： 1) 清除派生数据。 2) 重新启动 xCode 3) pods

的全新安装

如果能提供有关在哪里查找问题的帮助，我们将不胜感激。我很难过。谢谢！

通过逐项检查我的提交，我将其追踪到 SWIFT_WHOLE_MODULE_OPTIMIZATION 标志。从项目中删除此设置修复了它。我不知道为什么，但我想我会保留它以防它对某人有帮助。
