PanelKit for iOS
Applications using PanelKit can be seen in the showcase.


PanelKit is a UI framework that enables panels on iOS. A panel can be presented in the following ways:

  • Modally
  • As a popover
  • Floating (drag the panel around)
  • Pinned (either left or right)

This framework does all the heavy lifting for dragging panels, pinning them and even moving/resizing them when a keyboard is shown/dismissed.


A lot of effort has gone into making the API simple for a basic implementation, yet very customizable if needed. Since PanelKit is protocol based, you don’t need to subclass anything in order to use it. There a two basic principles PanelKit entails: panels and a PanelManager.


A panel is created using the PanelViewController initializer, which expects a UIViewController, PanelContentDelegate and PanelManager.


PanelContentDelegate is a protocol that defines the appearance of a panel. Typically the PanelContentDelegate protocol is implemented for each panel on its UIViewController.


class MyPanelContentViewController: UIViewController, PanelContentDelegate {

    override func viewDidLoad() {

        self.title = "Panel title"  

    var preferredPanelContentSize: CGSize {
        return CGSize(width: 320, height: 500)

A panel is explicitly (without your action) shown in a UINavigationController, but the top bar can be hidden or styled as with any UINavigationController.


PanelManager is a protocol that in its most basic form expects the following:

// The view in which the panels may be dragged around
var panelContentWrapperView: UIView {
    return contentWrapperView

// The content view, which will be moved/resized when panels pin
var panelContentView: UIView {
    return contentView

// An array of PanelViewController objects
var panels: [PanelViewController] {
    return []

Typically the PanelManager protocol is implemented on a UIViewController.
