Using non NS_ENUM objective-C enum in swift

Question

I am using the wahoo fitness API and it defines the following objective-C enum:

typedef enum
{
    /** No active connection. */
    WF_SENSOR_CONNECTION_STAT         


        

Answer 1

Here is the final complete solution:

WFSensorConnection+SensorConnectionEnumCategory.h

:

#import 

#import 

@interface WFSensorConnection (SensorConnectionEnumCategory)

typedef NS_ENUM(NSUInteger, ConnectionStatus) {
    ConnectionStatusIdle,
    ConnectionStatusConnecting,
    ConnectionStatusConnected,
    ConnectionStatusInterrupted,
    ConnectionStatusDisconnecting
};

- (ConnectionStatus) swift_connectionStatus;

@end

WFSensorConnection+SensorConnectionEnumCategory.m

:

#import "WFSensorConnection+SensorConnectionEnumCategory.h"

@implementation WFSensorConnection (SensorConnectionEnumCategory)

- (ConnectionStatus) swift_connectionStatus{
    if ( [self connectionStatus] == WF_SENSOR_CONNECTION_STATUS_IDLE ){
        return ConnectionStatusIdle;
    } else if ( [self connectionStatus] == WF_SENSOR_CONNECTION_STATUS_CONNECTING ){
        return ConnectionStatusConnecting;
    } else if ( [self connectionStatus] == WF_SENSOR_CONNECTION_STATUS_CONNECTED ){
        return ConnectionStatusConnected;
    } else if ( [self connectionStatus] == WF_SENSOR_CONNECTION_STATUS_DISCONNECTING ){
        return ConnectionStatusDisconnecting;
    } else if ( [self connectionStatus] == WF_SENSOR_CONNECTION_STATUS_INTERRUPTED ){
        return ConnectionStatusInterrupted;
    }
    return 0;
}

@end

Bridging-Header.h

#import "WFSensorConnection+SensorConnectionEnumCategory.h"

Usage:

var sensorConnection: WFSensorConnection?
var connState : ConnectionStatus = ConnectionStatus.Idle
connState = sensorConnection!.swift_connectionStatus()
switch connState {
    case ConnectionStatus.Idle:
...
}
