Passing data from view controller in Objective C to controller in Swift

Question

I'm trying to pass a value from a "pictureView" view controller written in objective C to a "profileView" view controller written with swift. I am trying to use the prepare for segue method using the following code

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
if([segue.identifier isEqualToString:@"unwindToProfileView"]){
    profileView *controller = (profileView *)segue.destinationViewController;
    controller.valueToPass = "PassedValue";
   }
}

The problem i'm running into is the "profileView" view controller is not recognized when called from the above method in objective C and xcode is throwing an error. I'm not sure if this is the correct way about transferring data from objective C to swift view controller or if I need to do something in the header or profileView.swift file.

Hopefully this is not a duplicate. I haven't been able to find anything regarding transferring data from objc VC to swift VC. Any help would be great.

Answer 1

Add an Objective-C Bridging Header and import the "profileView" view controller in that bridging header. You will then be able to reference the "profileView" view controller.

Answer 2

This isn't really an answer to my question, I never really got it working the way I wanted. But the way I got around the problem was creating a global variable in Obj C that Swift was able to see. You just have to make sure that global variable is included in your bridging header.
