Make sure you open the .xcworkspacefile rather than the project file (.xcodeproj) when working with pods. That should solve the issue with linking.
确保在使用 Pod 时打开.xcworkspace文件而不是项目文件 ( .xcodeproj)。这应该可以解决链接问题。

Some times you need just clean build. It helped me. To clean build go Product -> Clean

In you application, go to Target -> Build Settings, then you will find following attributes.
在您的应用程序中，转到 Target -> Build Settings，然后您将找到以下属性。
- CLANG_WARN_INFINITE_RECURSION
- CLANG_WARN_SUSPICIOUS_MOVE
- GCC_NO_COMMON_BLOCKS
- CLANG_WARN_INFINITE_RECURSION

Set values for those as NO, then clean and build the project.
将这些值设置为 NO，然后清理并构建项目。

Close you project and go to project path and select your project with .xcworkspaceinstead of .xcodeproj.
Reason your existing project doesn't contain any library you linked.
关闭您的项目并转到项目路径并使用.xcworkspace而不是选择您的项目.xcodeproj。您现有项目不包含您链接的任何库的原因。

Remove the local files of WikitudeSDKfrom target. Xcode is getting confused between the paths of library, which one to chose- pod or local.
从目标中删除WikitudeSDK的本地文件。Xcode 在库的路径之间感到困惑，选择哪个 - pod 或本地。
Also try reinstalling podfile and remove wikitude from pod file to. IN linker search path settings, in build settings, check the paths mentioned to find the required library.
也尝试重新安装 podfile 并从 pod 文件中删除 wikitude。在链接器搜索路径设置中，在构建设置中，检查提到的路径以找到所需的库。
Lastly install gems before updating pods
最后在更新 pod 之前安装 gems

You have to check Link Binary With Libraries option. Sometimes you build pod that is not in your project anymore.
您必须检查 Link Binary With Libraries 选项。有时您构建的 pod 不再存在于您的项目中。
On the left panel click on your project name, then under Targets again (click on name), then Build Phases > Link Binary With Files. Delete everything that you dont use.
在左侧面板上单击您的项目名称，然后再次在 Targets 下（单击名称），然后Build Phases > Link Binary With Files。删除您不使用的所有内容。

the solution for me was open the .xcworkspace file insted of .xcodeproj located inside my '/platforms/ios' folder.
我的解决方案是打开位于我的“/platforms/ios”文件夹内的 .xcodeproj 的 .xcworkspace 文件。

I got same error like duplication of "variable name". You need to check all variable and function name for all .m file and make sure it's not same in any other file.Then clean and build.
我遇到了同样的错误，比如“变量名”重复。您需要检查所有 .m 文件的所有变量和函数名称，并确保它在任何其他文件中都不相同。然后清理并构建。
It's working for me.
它对我有用。
