实现一个带有命名参数的委托

Question

我试图符合Objective-C中编写的委托协议。一个特别需要的方法是给我麻烦。它看起来像这样：

-(void)didReceiveData:(NSData*)data Device:(DFBlunoDevice*)dev; 

Xcode的雨燕自动完成建议我实现这样的：

func didReceiveData(data: NSData!, device dev: DFBlunoDevice!){...} 

但以此来传递错误：

Does not conform to protocol 'DFBlunoDelegate'.

公告中的命名资本的区别参数“设备”。改变函数读取

func didReceiveData(data: NSData!, Device dev: DFBlunoDevice!){...} 

导致新的错误：

Method 'didReceiveData(:Device:)' has different argument names from those required by protocol 'DFBlunoDelegate' ('didReceiveData(:device:)')

我如何能实现用斯威夫特命名参数Objective-C的委托方法？

这个问题是在问题的评论回答rmaddy：

The Objective-C method is named with poor capitalization. Device: should be device:. Maybe that will help when bridging to Swift.
