Why doesn't return return stop the program?

So, I have a function that checks if the user is viewing their profile or not. and here is my function.

func isUserViewCurrentUser() -> Bool {
    guard let user = userDataDelegate?.userData() else {
        return false
    }

    if user == Current.user {
        print("returning false: USER IS CURRENT USER")
        return false
    } else {
        print("returning true: USER IS NOT CURRENT USER")
        return true
    }

 }

      

        
        
        
      

    

Then I will only run my function in the view, the code should stop after I type something:

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(true)
    if isUserViewCurrentUser() == true {
        self.navigationItem.rightBarButtonItem = nil
        self.navigationItem.leftBarButtonItem = nil
        return
    } else {
        return
    }

    if let userID = userDataDelegate?.userData().userID {
        retrieveFollowerNumbers(userIdentifier: userID)
        return
    }

 }

      

        
        
        
      

    

But my console was typing "returning true: USER IS NOT USER ONLY" for a thousand times and never stops. I've looked everywhere for code that I never run isUserViewCurrentUser()

in a for loop or any loop.

This is my userData:

protocol SendUserDataDelegate {

    func userData() -> User
}

      

        
        
        
      

    

didSelect TableViewCell:

if let user = filteredUsers?[indexPath.row] {
        userToPass = user
        profileController?.userDataDelegate = self
        self.navigationController?.pushViewController(profileController!, animated: true)

    }

      

        
        
        
      

    

And this code on my cellRowAtIndexPath:

if isUserViewCurrentUser() == true {
            cell.bioAndFollowStackView.addSubview(cell.followButtonOutlet)
        } else {
            if cell.followButtonOutlet != nil {
                cell.followButtonOutlet.removeFromSuperview()
            }
        }

      

        
        
        
      

    

dispatching a custom object when the user inserts a table cell into another viewController. and I call it whenever I want to get a reference to the user object
