让 Google Fabric / Crashlytics 与 Xcode 10 一起工作的诀窍是什么？

编辑：感谢到目前为止所有发表评论的人。到目前为止我尝试过的：

尝试重新安装 pod/清除 pod 缓存 尝试清理构建文件夹，然后重新启动 xcode 尝试使用 -ObjC 链接器标志。看起来这个标志确实与问题有关，但不幸的是，我需要激活这个标志，因为我使用的 Objective-c 框架在类上有静态类别

【问题讨论】：

我收到“ld: 163 架构 arm64 的重复符号”

我对 Xcode 10 beta5 有同样的问题。它在 beta4 上没有问题。到目前为止，我只能说在链接器中使用“-ObjC”或“-force_load”标志存在问题。我还可以确认它仅无法为真实设备构建并且对于模拟器没有问题。苹果需要解决这个问题。

【参考方案1】：

使用 Xcode 10b6（今天早上发布）为我修复了！
