JWPlayerViewController.player return with nil after updating to 4.18.0

[iMustafaAbozaina]

When subclassing JWPlayerViewController and upgrading to version 4.18.0, initializing the subclass with super.init() results in a crash with the error: "Use of unimplemented initializer 'init(nibName:bundle:)' for class 'VideoPlayerViewController'". Attempting to resolve this by using super.init(nibName: nil, bundle: nil) prevents the crash but causes playerViewController.player to become nil, leading to another crash.
