typedef enum in swift

Question

I'm rewriting my Objective C application in Swift, and I have a question about enum's. In Objective C you would do;

typedef enum {
stopped,
running
} TimerState;

which returns the errors, Consecutive Declarations on a line must be separated by ‘;’ — Expected declaration — Expected identifier in enum declaration. I read some of the documentation about this and found that you don't put typedef before enum's anymore. So in swift I thought it would be:

enum {
stopped,
running
} TimerState;

But I do not know what to do with the TimerState, does that go inside the curly braces? What do i do. No smart ass comments either, please. Thanks in advance.

That is not how you declare an enum in Swift. You cannot simply list the values like you could in C. An enum could be accomplished in C with the following technique.

enum TimerState {
    stopped,
    running
};

In swift, you have to use the case keyword.

enum TimerState {
    case stopped
    case running
}

As for the typedef, there is a typealias in swift.

typealias SomeNewEnum = TimerState

Edit: If you want to assign a raw type to your enum, you can do so.

enum TimerState: Int {
        case stopped = 0
        case running // 1
}
