Objective-C enum not recognized in Swift - objective-c

Question

I have a delegate method that passes an enum as an argument:
func gestureRecognizer(gestureRecognizer: JTTableViewGestureRecognizer!, commitEditingState state: JTTableViewCellEditingState, forRowAtIndexPath indexPath: NSIndexPath!) -> Void {
//....
}
The enum is JTTableViewCellEditingState. It's implementation is in the same header file as the delegate method. It's as follows:
typedef enum {
JTTableViewCellEditingStateMiddle,
JTTableViewCellEditingStateLeft,
JTTableViewCellEditingStateRight,
} JTTableViewCellEditingState;
Yet trying to reference a state, for example Left, gives an error:
if state == JTTableViewCellEditingState.Left {
'JTTableViewCellEditingState.Type' does not have a member named 'Left'
Trying to do it the old, Objective-C way, like some kind of peasant, gives me a different, more expected, error:
if state == JTTableViewCellEditingStateLeft {
Cannot invoke '==' with an argument list of type '(JTTableViewCellEditingState, JTTableViewCellEditingState)'
I'm wondering how I should overcome this issue? I believe referencing Objective-C enums has worked just fine in the past.

Answer 1

This type of enum decleration causes problems in swift. I had similar problem. My solution is to create a helper objective-c method that does comparison and use that method in swift whenever == is needed.
Other solution may be refactor that code if you can and convert it proper enum decleration in objective-c.
typedef NS_ENUM(NSInteger, MyEnum) {
MyEnumValue1,
MyEnumValue2
};

Answer 2

Can you use NS_ENUM instead? And then try JTTableViewCellEditingState.JTTableViewCellEditingStateLeft or even .JTTableViewCellEditingStateLeft to access your enum. If you can't change it to NS_ENUM, please have a look at Using non NS_ENUM objective-C enum in swift

Answer 3

In my environment - Xcode Version 6.1.1 (6A2006):
typedef enum {
JTTableViewCellEditingStateMiddle,
JTTableViewCellEditingStateLeft,
JTTableViewCellEditingStateRight,
} JTTableViewCellEditingState;
is exported to Swift as:
struct JTTableViewCellEditingState {
init(_ value: UInt32)
var value: UInt32
}
var JTTableViewCellEditingStateMiddle: JTTableViewCellEditingState { get }
var JTTableViewCellEditingStateLeft: JTTableViewCellEditingState { get }
var JTTableViewCellEditingStateRight: JTTableViewCellEditingState { get }
So, this should works:
func gestureRecognizer(gestureRecognizer: JTTableViewGestureRecognizer!, commitEditingState state: JTTableViewCellEditingState, forRowAtIndexPath indexPath: NSIndexPath!) -> Void {
if state.value == JTTableViewCellEditingStateLeft.value {
// ...
}
}
