Presenting custom Presentr triggered warning message: Warning: Attempt to present * on *whose view is not in the window hierarchy"

[EllisShen]

Thanks for your attention.

I have a UITabBarController in which contains multiple NotificationCenter listeners. For every listener, I use Presentr as a bottom half modal to notify the user an event occur or a new message is received. I import Presentr from the GitHub repo directly (I figured out that the code of v1.3.2 on Cocoapod has some difference with the latest Github version).

It works fine if I use Presentr with the predefined .bottomHalf config. But when I tried with custom settings like below, it will always trigger a warning message: Attempt to present * on *whose view is not in the window hierarchy", and sometimes it caused the app crashed.

    let presenter: Presentr = {
        let width = ModalSize.fluid(percentage: 0.96)
        let height = ModalSize.fluid(percentage: 0.46)
        let center = ModalCenterPosition.bottomCenter
        let customType = PresentationType.custom(width: width, height: height, center: center)

        let customPresenter = Presentr(presentationType: customType)
        customPresenter.transitionType = .coverVertical
        customPresenter.dismissTransitionType = .coverVertical
        customPresenter.dismissAnimated = true
        customPresenter.roundCorners = true
        customPresenter.cornerRadius = 16
//        customPresenter.backgroundColor = .green
//        customPresenter.backgroundOpacity = 0.5
        customPresenter.dismissOnSwipe = true
        customPresenter.dismissOnSwipeDirection = .top
        return customPresenter
    }()

Do you have any suggestion? I didn't figure out the reason caused this error. Thank you so much!
