Transparent background for modally presented viewcontroller
Fixed it.
The problem was that presentViewController does not keep the view that I was covering.
viewController.modalPresentationStyle = .overCurrentContextdid the trick.
Part of the solution is hidden in the question. You need three lines to make the background transparent, viz. isOpaque = false backgroundColor = .clear & set the modalPresentationStyle
Here's the full solution. In the calling View Controller, call this function:
func presentModal() { let modalController = ModalViewController() modalViewController.modalPresentationStyle = .overCurrentContext present(modalViewController, animated: true, completion: nil)}And in ModalViewController's viewDidLoad():
override func viewDidLoad() { super.viewDidLoad() view.isOpaque = false view.backgroundColor = .clear // try other colors, say: .white or black with Alpha etc.}
