【问题描述】：

我将在下面列出我的 pods。

  # Pods for SalesForceSDK
  pod 'SalesforceAnalytics', :path => 'mobilesdkpath/SalesforceMobileSDK-iOS'
  pod 'SalesforceSDKCore', :path => 'mobilesdkpath/SalesforceMobileSDK-iOS'
  pod 'SmartStore', :path => 'mobilesdkpath/SalesforceMobileSDK-iOS'
  pod 'SmartSync', :path => 'mobilesdkpath/SalesforceMobileSDK-iOS'
  pod 'SalesforceSwiftSDK', :path => 'mobilesdkpath/SalesforceMobileSDK-iOS'
  pod 'PromiseKit', :git => 'https://github.com/mxcl/PromiseKit', :tag => '5.0.3'

XCode 版本为 12.4

如果我在设备上运行，错误报告是：-

    "OBJC_CLASS$_SFSDKLogger", referenced from: 
         OBJC_CLASS$_SFSDKSmartStoreLogger in SFSDKSmartStoreLogger.o

【解决方案1】：

这是一个奇怪的问题。现在它工作正常，但我没有触及上个月的代码。

当我发布这个问题时，我做了同样的事情。输入以下命令。

pod deintegrate 和 pod install
