我对 Xcode 开发还比较陌生。本质上，我正在开发的项目使用了PolarBleSdk库，该库也具有 RxSwift 依赖项。我将它们添加为框架/编译模块，上周两者都运行正常。今天我去运行我的项目并得到以下错误：
Module compiled with Swift 5.2 cannot be imported by the Swift 5.3 compiler: /Users/admin/eva-official/eva/eva/ios/PolarBleSdk.framework/Modules/PolarBleSdk.swiftmodule/x86_64-apple-ios-simulator.swiftmodule
我查看了 SO 上的错误，发现几个相同的问题都具有相同的解决方案，最详细的答案如下：
使用 Swift 5.1 编译的模块无法被 Swift 5.1.2 编译器导入
因此，当我尝试此解决方案时，BUILD_LIBRARY_FOR_DISTRIBUTION = YES;我收到此错误：
CompileSwiftSources normal x86_64 com.apple.xcode.tools.swift.compiler (in target 'Runner' from project 'Runner')
