3,134 PointsHow do I update a viewController or label when dismissing a modul in Swift?
The main page of a workout app I'm working on contains a label with different exercises. From the main page you can open a "settings" modul where it's possible to adjust you skill level.
When I dismiss the settings modul I need the text label to be refreshed, so it reflects the new settings.
How do I make the label (or the ViewController) refresh, when I dismiss the settings modul?

I had the same issue, when creating my first app! I solved it using presentingViewController. I put the code how I solved this (with detailed explanation) in a gist on GitHub https://gist.github.com/bcye/8fa53524e6d529162a0750471fdda0a3
Hope that's all it needs for you.
Bruce.

Are you navigating via segues ? If so you can use an unwind segue.
