Switch Statement Not Handling NS_ENUM values

I have an enum defined in a objective-c header that looks like this:

#import <UIKit/UIKit.h>
#import <MapKit/MapKit.h>
@interface CustomerAndProspectMapViewController : UIViewController<MKMapViewDelegate>
typedef NS_ENUM(NSInteger, TypeEnum)
{
    PROSPECT,
    CUSTOMER

};
@end

Then in the implementation I have a function that takes a TypeEnum as a parameter and uses a switch to run some conditional code:

-(void) handleTestNavigation:(NSString *)accountId :(TypeEnum)accountType
{
    switch(accountType)
    {
        CUSTOMER:
        {
            [self performSegueWithIdentifier:@"customerDetails" sender:accountId];
            break;
        }

        PROSPECT:
        {
            [self performSegueWithIdentifier:@"prospectDetails" sender:accountId];
            break;
        }

    }

}

As you can see, both options for the enum have a corresponding path in the switch. Yet for some reason, I get a compiler warning saying

Enumeration values 'PROSPECT' and 'CUSTOMER' not handled in switch

Just to make sure, I put some breakpoints in that method. As the warning indicated, it fell though without ever hitting a case. I also tried renaming the enum values just to make sure they were not conflicting somewhere and still nothing. I'm completely stumped here. Any help would be much appreciated.

You forgot the keyword case.

switch(accountType)
{
    case CUSTOMER:
    {
        [self performSegueWithIdentifier:@"customerDetails" sender:accountId];
        break;
    }

    case PROSPECT:
    {
        [self performSegueWithIdentifier:@"prospectDetails" sender:accountId];
        break;
    }

}

NOTE: The code you posted created two labels.
