Debugger constraint warnings related to KeyboardAssistantBar and Presentr?

[robcecil]

Not sure if this is something that lies in my code, but when I invoke the keyboard in a UIView that has been Presentr'ed, I see Xcode spill its guts with these warnings.

Any ideas?

( "<NSAutoresizingMaskLayoutConstraint:0x604000299870 h=--& v=--& UIKeyboardAssistantBar:0x7fe96f766bc0.height == 0 (active)>", "<NSLayoutConstraint:0x60c000292d40 V:|-(0)-[_UIButtonBarStackView:0x7fe96f7683f0] (active, names: '|':UIKeyboardAssistantBar:0x7fe96f766bc0 )>", "<NSLayoutConstraint:0x60c000292ed0 V:[_UIButtonBarStackView:0x7fe96f7683f0]-(0)-| (active, names: '|':UIKeyboardAssistantBar:0x7fe96f766bc0 )>", "<NSLayoutConstraint:0x60c00029d790 'UIButtonBar.maximumAlignmentSize' _UIButtonBarButton:0x7fe96f78ca90.height == UILayoutGuide:0x60c0001b8720'UIViewLayoutMarginsGuide'.height (active)>", "<NSLayoutConstraint:0x60c000292890 'UIView-bottomMargin-guide-constraint' V:[UILayoutGuide:0x60c0001b8720'UIViewLayoutMarginsGuide']-(9)-| (active, names: '|':_UIButtonBarStackView:0x7fe96f7683f0 )>", "<NSLayoutConstraint:0x60c0002927f0 'UIView-topMargin-guide-constraint' V:|-(10)-[UILayoutGuide:0x60c0001b8720'UIViewLayoutMarginsGuide'] (active, names: '|':_UIButtonBarStackView:0x7fe96f7683f0 )>" )

My presenter:

lazy var loginPresenter: Presentr = { [unowned self] in
    let width = ModalSize.custom(size: 400)
    let height = ModalSize.custom(size: 500)
    let p = CGPoint(x: self.view.frame.origin.x + (self.view.frame.width / 2) - 200, y: 70)
    let center = ModalCenterPosition.customOrigin(origin: p)
    let customType = PresentationType.custom(width: width, height: height, center: center)
    let presenter = Presentr(presentationType: customType)
    presenter.blurBackground = false
    presenter.backgroundColor = UIColor.black
    presenter.backgroundOpacity = 0.4
    presenter.transitionType = .crossDissolve
    presenter.dismissTransitionType = .crossDissolve
    presenter.roundCorners = false
    presenter.dismissOnSwipe = false
    presenter.dismissOnTap = false
    presenter.keyboardTranslationType = .moveUp
    let shadow = PresentrShadow(shadowColor: UIColor.black, shadowOpacity: 0.3, shadowOffset: CGSize(width: 5, height: 5), shadowRadius: CGFloat(4.0))
    presenter.dropShadow = shadow
    return presenter
}()
