致命错误：无法使用Objective Sharpie创建__weak引用

Question

当我试图将一个吊舱绑定到Xamarin时，我遇到了一些错误。

我执行了以下命令：

sharpie pod init ios libPusher
sharpie pod bind

但这给了我这样的错误：

- (RACSignal *)rac_valuesAndChangesForKeyPath:(NSString *)keyPath options:(NSKeyValueObservingOptions)options observer:(__weak ...
                                                                                                                        ^

      cannot create __weak reference in file using manual reference counting

我尝试编辑Pods.xcodeproj并将每个项目设置为使用自动引用计数，但这似乎不起作用。

我是否需要添加一个clang选项来启用自动引用计数，还是还有其他事情要继续？

在Xcode和Build Setting集合中打开有问题的项目：
