Cannot access Swift var from Objective-C View controller - iOS

I have an app with both Objective-C and Swift based view controllers. I am programatically opening a Swift based view controller from one of my Objective-C based view controllers. The problem I am having is that I can't access the Swift variables from my Objective-C code.

My Swift code:

@IBOutlet weak var profPicture: UIImageView!
@IBOutlet weak var profVerified: UIImageView!
@IBOutlet weak var profName: UILabel!
var passedUser:PFUser!

My Objective-C code:

MyProfileViewController *screen = [[MyProfileViewController alloc] initWithNibName:@"Main" bundle:nil];
self.dataPass = screen;
dataPass.profName.text = @"";
screen.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[self presentViewController:screen animated:YES completion:nil];

I am able to access @ properties like IBOutlets, but I can't access and edit the var objects.

I am doing this, because I want to pass data into the Swift based view controller from the Objective-C based view controller when I am presenting the Swift based view controller.

Why can't I access the var objects?

Here is the error I am getting:

enter image description here

The error is as follows:

Property 'passedUser' not found on object of type
'MyProfileViewController *'

Thanks for your time, Dan.

You will have to declare the variable as public.

By default, the variables have internal access, that means they can be accessed only from inside their module. Obj-C code is not in their module.
