swift - How can I properly reload the UIViewController after dismiss method is called?

Question

I have 2 viewControllers named vcA and vcB. vcA has navigationController and vcB is just viewController which don't have navigationController. I saved text data in a file in vcB, and I wanna show that text in vcA when I come back to vcA after the dismiss method is called. I thought reloading vcA after dismiss is called is the proper way to show text, but I figured out that it might be difficult to do that between vcA and vcB, because vcA has navigationController but vcB doesn't have navigationController. How can I refresh vcA?

Answer 1

You can use self.present over self.dismiss. Like this:

let vc = vcA()

And here you can pass data. For example, if vcA() has a var called text that is a string you can use vc.text = "something". And this data will go with the self.present method

vc.modalPresentationStyle = .fullScreen

self.present(vc,animated: true, completion: nil)
