Embedded controller has nil outlets

Question

In the storyboard, I embedded controller B into controller A. However when I try to access the outlets in controller B from controller B's viewDidLoad, viewWillAppear, or viewDidAppear methods, they're nil.

Why would an embedded controller's own outlets be nil after the view has loaded?

Answer 1

You are building your LiveView controls in a storyboard scene that's not being used. Move your various views and buttons into the scene that's connected to your container view by the embed segue.
