Passing data from a Swift Controller to an Objective-C controller

Question

I'm trying to pass a simple string from a Swift Controller to an Objective-C controller, but unfortunately it doesn't work.

Error I get:

Value of type 'EUIDViewController' has no member 'stringPassed'

Swift Code sending string

let pvc = EUIDViewController(nibName: "ScannerViewController", bundle: nil)
if isHasCameraPermission {
    pvc.stringPassed = "test"
    present(pvc, animated: true, completion: { _ in })
}

Objective-C code receiving the string

@property (strong, nonatomic) NSString* stringPassed;

- (void)viewDidLoad {
    [super viewDidLoad];
    [self initOCR];
    NSLog(@"String: %@", self.stringPassed);
}

Update: I did #import "EUIDViewController.h" into the bridging-header

You need to declare stringPassed property in .h means header file of that ViewController.

@interface ViewController : UIViewController

@property (strong, nonatomic) NSString* stringPassed;

@end
