I got this problem too & also don't know what happened. But it still works well, so I just ignore it

The problems are the following 3 lines of code in the following methods in 'Window.swift'

internal func showFrameView() {

       layer.removeAllAnimations()
        makeKeyAndVisible()
        frameView.center = center

        // ------------------------------
        // currently
        frameView.alpha = 1.0 
        // how it should be
        frameView.backgroundColor = frameView.backgroundColor?.colorWithAlphaComponent(1.0)
        // ------------------------------

        hidden = false
    }

and

internal func hideFrameView(animated anim: Bool, completion: ((Bool) -> Void)? = nil) {
        let finalize: (finished: Bool) -> (Void) = { finished in
            if finished {
                self.hidden = true
                self.resignKeyWindow()
            }

            self.willHide = false
            completion?(finished)
        }

        if hidden {
            return
        }

        willHide = true

        if anim {
            UIView.animateWithDuration(0.8, animations: {

                 // ------------------------------
                // currently, causes error message
                self.frameView.alpha = 0.0 
                 // how it should be
                self.frameView.backgroundColor = self.frameView.backgroundColor?.colorWithAlphaComponent(0.0)
                // ------------------------------

                self.hideBackground(animated: false) 
            }, completion: finalize)
        } else {

            // ------------------------------
            // currently, causes error message
            self.frameView.alpha = 0.0 
             // how it should be
            self.frameView.backgroundColor = self.frameView.backgroundColor?.colorWithAlphaComponent(0.0)
             // ------------------------------

            finalize(finished: true)
        }
    }

Please see #6 - There's an idea for a workaround (nesting the view in a containing UIView and animating that one), but I haven't gotten to implementing yet.
