GoogleCast框架在iOS 14上崩溃

Question

我试图在我的项目中使用google cast sdk，由于某种原因，它崩溃了，没有给出一个正确的错误：

*终止应用程序由于未登录的异常'NSInvalidArgumentException'，原因：‘* -__NSPlaceholderDictionary initWithObjects:forKeys:count:：尝试从对象中插入零对象’终止时类型为NSException的未命名异常

我看到一个可能的改变在那个时候是与Podspec相关的，其中包括cast SDK。其中一些行以前没有出现过，这导致在包和崩溃中缺少Google Cast参考资料(下面是部分podspec)：

Pod::Spec.new do |s|
  s.dependency 'google-cast-sdk-no-bluetooth', '= 4.5.0'
  s.xcconfig =  {
      'CLANG_ALLOW_NON_MODULAR_INCLUDES_IN_FRAMEWORK_MODULES' => 'YES',
      'OTHER_LDFLAGS' => '-objc -ObjC -lc++ -framework "GoogleCast"',
      'GCC_SYMBOLS_PRIVATE_EXTERN' => 'YES'
  }
