在目标C代码中使用NSLOG在Swift Enum上使用NSLOG时exc_bad_access崩溃

我正在崩溃线程21：exc_bad_access（代码= 1，地址= 0x101e）在尝试在我的目标C代码中记录Swift Enum时。

枚举通过OBJ C代码的Swift函数调用的完成处理程序传递，

 NSLog(@"Completed with operation: %@", operation);

枚举：

@objc public enum Operation: Int {
    case Unknown
    case Operation1
    case Operation2
    case Operation1And2
}

我疲倦了以下2个变体，并且该应用程序无法构建。 Xcode存在一个问题，可以防止我看到实际错误是什么。

 NSLog(@"Completed with operation: %@", [operation description]);

 NSLog(@"Completed with operation: %@", [operation value]);

我想在此枚举上进行基本操作，例如记录其值，做布尔比较。但是我对如何做这件事是对目标C的新手有些失落的。

I am getting a crash Thread 21: EXC_BAD_ACCESS (code=1, address=0x101e) when trying to log a Swift enum in my Objective C code.

Enum passed in as the result of a completion handler on Swift function call from Obj C code:

 NSLog(@"Completed with operation: %@", operation);

Enum:

@objc public enum Operation: Int {
    case Unknown
    case Operation1
    case Operation2
    case Operation1And2
}

I tired the following 2 variations and the app failed to build. There is an issue with Xcode that prevents me from being able to see what the actual error was.

 NSLog(@"Completed with operation: %@", [operation description]);

 NSLog(@"Completed with operation: %@", [operation value]);

I want to do basic operation on this enum like log its value, do boolean comparisons. But I am a little lost on how to do that as fairly new to Objective C.
