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:

The error is as follows:

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

Thanks for your time, Dan.

Solution

  • 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.
