Environment

{top,bottom}InteractionBuffer properties are removed from FloatingPanelLayout since v2. So you need to specify a panel boundary as follows.

func floatingPanelDidMove(_ vc: FloatingPanelController) {
    if vc.isAttracting == false {
        let loc = vc.surfaceLocation
        let minY = vc.surfaceLocation(for: .full).y - 6.0
        let maxY = vc.surfaceLocation(for: .tip).y + 6.0
        vc.surfaceLocation = CGPoint(x: loc.x, y: min(max(loc.y, minY), maxY))
    }
}]

From README > Specify the panel move's boundary

It doesn't work when we move the panel with speed. When released, the panel jumps up for a while

Hi, @ravilich86 If vc.isAttracting == false is removed, the panel doesn't jump up beyond the boundary after releasing it. However a floating panel would have no collision behavior so that it looks settle for a while at the top of the boundary.

@scenee thanks a lot for your work!

I've also stumbled upon this issue and your workaround works for me. However, I'm wondering, is it possible to find a better solution? Ideally, as a user, I expect that after surfaceLocation passes the limit Y, the scrollView that we provide via track(scrollView: UIScrollView) would start scrolling instead. With your suggested workaround, it's possible to scroll the content only after the panel is at the .full state, but for that you need to lift off the finger and then start scrolling. Would be perfect if you didn't have to lift off your finger.

Good catch, @armanarutiunov! I wasn’t aware of the use case. Thank you for letting me know. I’m addressing #455 now, which looks related to your suggestion. I would consider it to improve the continuous scroll of a panel as well.
