如何解决这个问题。谢谢。

解决方案

更新：我推荐Stefan Scoarta的 use_frameworks！添加到您的pod文件中。

原始答案：
请确保您已配置桥接标头，如Apple的在Cocoa和Objective-C中使用Swift 文档。

为了将一组Objective-C文件导入与Swift代码相同的应用程序目标中，您需要依靠Objective-C桥接头将这些文件公开到Swift中......或者，您可以通过选择File> New> File>（iOS或OS X）> Source> Header File。

解决方案

Updated: I recommend Stefan Scoarta's answer to add use_frameworks! to your podfile if you're targeting iOS 8 or higher and can use frameworks.

Original answer: Make sure that you've configured a bridging header as described in Apple's Using Swift with Cocoa and Objective-C document.

To import a set of Objective-C files in the same app target as your Swift code, you rely on an Objective-C bridging header to expose those files to Swift…Alternatively, you can create a bridging header yourself by choosing File > New > File > (iOS or OS X) > Source > Header File.
