dyld:找不到符号:_OBJC_CLASS _ $ _ Reachability，Xcode 11崩溃 [英] dyld: Symbol not found: _OBJC_CLASS_$_Reachability, Xcode 11 crash

问题描述

仅在安装pod PusherSwift 后，我才遇到以下崩溃.

I encountered the following crash only after installing the pod PusherSwift.

在应用程序启动时，使用以下崩溃日志导致崩溃:

On application launch, getting a crash with the following crash logs:

我直接复制了以下文件到我的项目.当我检查 PusherSwift.podspec 时，它具有 ReachabilitySwift 作为依赖项.所以，我猜这就是问题的出处.我尝试删除 Reachability file 直接复制到我的项目中，但是运行后，崩溃仍然存在.

I have the following file copied directly to my project. As I checked PusherSwift.podspec, it has ReachabilitySwift as a dependency. So, I'm guessing that's where the problem came from. I tried deleting the Reachability file that was directly copied on my project, but after running, the crash is still there.

我也有Tony Million的 Reachability 库，但我不知道哪个库

I also have Reachability library by Tony Million through another pod, but I have no idea which one.

我还尝试在一个新的新项目上实现 PusherSwift ，它工作得很好.但是当我尝试现有项目时，它总是崩溃.

I also tried implementing PusherSwift on a fresh new project and it works perfectly fine. But when I try on my existing project, it always crashes.

是否需要导入某些内容(例如头文件)或要添加的内容?我一直看到在 Frameworks，Libraries和Embedded Content 上添加框架.我试图在此添加 Reachability.framework ，但没有成功.

Is there something I have to import like the header file or something to add? I keep seeing to add the framework on Frameworks, Libraries, and Embedded Content. I tried to add Reachability.framework there, but it did not work.

希望有人可以提供帮助.

Hoping someone could help.

谢谢！

推荐答案

目前，我只是对此进行了变通.我只是从 PusherSwift 中手动复制了需要的文件，而不是通过Cocoapods安装了它.然后，pod安装了它的依赖项.

For the time being, I just did a workaround on this. I just manually copied the files I need from PusherSwift, instead of installing it via Cocoapods. Then, pod installed its dependencies.
