container view calls parent func in swift

In the storyBoard "parent" scene with its parentVC.swift, there is a containerView with embedded segue with its containerVC.swift.
I am able to call containerView.myFunc() in the parentVC viewDidLoad() with no problems.
How can I call a custom func defined in parentView from an action of a button in containerView.

self.parentViewController.myCustomFunc()

I get

Value of type UIViewController? has no member myCustomFunc

You need to cast parentViewController so the compiler knows which functions are available. The definition is simply UIViewController? which, as the error says, doesn't have your function.

Try:

if let vc = self.parentViewController as? parentVC {
    vc.myCustomFunc()
}
