- 如何从你自己的项目中导入自己的课程
As suggested here I've been able to import my existing Objective-C code into a .swift file via the bridging header. As of yet I've been unable to do something similar with a swift playground - it does not seem to recognise the header in the same way that a swift file does.
正如这里提到的，我已经能够通过桥接头将现有的Objective-C代码导入到.swift文件中。到目前为止，我还不能在快速运动场上做类似的事情——它似乎不能像快速文件那样识别标题。
Interestingly, and possibly suggestive of a negative to my question is that playgrounds do not appear to share the concept of target membership like .swift/.m
有趣的是，这也可能暗示了我的问题的消极之处在于，运动场似乎并不像。swift/。m这样的目标成员
Anyone had any success with this or perhaps a different mechanism?
有人在这个或者可能是另一个机制上成功过吗?

See Using Swift with Cocoa and Objective-C for how to set up an Xcode project for importing Swift into Objective-C. Then create a playground in that project and the playground should be able to work with any of the ObjC classes in the project.
