Error using Objective C typedef enum in Swift 3

I try to use Reachability class provided by Apple.

It has an Objective-C enum like this:

typedef enum : NSInteger {
    NotReachable = 0,
    ReachableViaWiFi,
    ReachableViaWWAN
} NetworkStatus;

And in Swift I'm doing something like this:

if let networkReachability = notification.object as? Reachability {
    let remoteHostStatus = networkReachability.currentReachabilityStatus()
    let center = NotificationCenter.default
    var notificationKey: String

    if (remoteHostStatus == NetworkStatus.NotReachable) {
        ...
    }
}

But I get the error:

Type 'NetworkStatus' has no member 'NotReachable'

What am I doing wrong? How can I use that Objective-C enum in Swift?

typedef enum : NSInteger {
    NotReachable = 0,
    ReachableViaWiFi,
    ReachableViaWWAN
} NetworkStatus;

This is an "ordinary" C enum. So it arrives into Swift with no namespacing; the names NotReachable, ReachableViaWiFi, and ReachableViaWWAN can be used directly. Note that there is no preceding dot (.).

If you define your enum like follows, it will be accessible as NetworkStatus.NotReachable, etc.:

typedef NS_ENUM(NSInteger, NetworkStatus) {
    NotReachable = 0,
    ReachableViaWiFi,
    ReachableViaWWAN
};
