Q:

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

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

A:

You need to declare stringPassed property in .h means header file of that ViewController.
@interface ViewController : UIViewController

@property (strong, nonatomic) NSString* stringPassed;

@end
