CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:

$ gem install cocoapods

To integrate FAPanel into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '9.0'

target '<Your Target Name>' do
pod 'FAPanels'

Then, run the following command:

$ pod install


Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

To integrate FAPanels into your Xcode project using Carthage, specify it in your Cartfile:

github "fahidattique55/FAPanels" >= 0.2.0

Run carthage update to build the framework and drag the built FAPanels.framework into your Xcode project.


Step 1

  • Set the root window as FAPanel controller as shown in below image,

Alt text

Step 2

  • Add the following code in AppDelegate.swift file,

//  Load the Controllers 

let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)

let leftMenuVC: LeftMenuVC = mainStoryboard.instantiateViewController(withIdentifier: "LeftMenuVC") as! LeftMenuVC

let rightMenuVC: RightMenuVC = mainStoryboard.instantiateViewController(withIdentifier: "RightMenuVC") as! RightMenuVC

let centerVC: CenterVC = mainStoryboard.instantiateViewController(withIdentifier: "CenterVC1") as! CenterVC
let centerNavVC = UINavigationController(rootViewController: centerVC)

//  Set the Panel controllers with just two lines of code

let rootController: FAPanelController = window?.rootViewController as! FAPanelController

  • All done! Run the code and see the magic.

Step 2 (Continue - Panel Controllers)

  • Don't want to set RightMenuVC then just remove the right panel code i.e,

//  This is the code to set all panels 


//  Updated code which have only left and center panels 


//  Similarly, if left panel is not needed the remove the left panel code.


//  In case you only want the center panel, then update code to


Step 2 (Continue - Panel Configurations)

  • Configre the Panels before setting the panels

rootController.configs.rightPanelWidth = 80
rootController.configs.bounceOnRightPanelOpen = false

//  Should Pan from edge? Add these lines of code, 

rootController.configs.panFromEdge = false
rootController.configs.minEdgeForLeftPanel  = 70
rootController.configs.minEdgeForRightPanel = 70


//  For more configurations and their details, Please have a look into ``` FAPanelConfigurations.swift ``` file 

Access Panel

  • Panel can be accessed from any view controller,

panel?.configs = FAPanelConfigurations()

Open/Close Panels

  • Open Left or Right panels with/without animations

panel?.openLeft(animated: true)
panel?.openRight(animated: true)

  • Open/Close Panels Preview

Change/Remove Panels

  • Change Left, Right or Center Panel from any view controller

//  Change Center panel

let centerVC: UIViewController = mainStoryboard.instantiateViewController(withIdentifier: "CenterVC2")
let centerNavVC = UINavigationController(rootViewController: centerVC)


//  Change Left panel

let leftVC: UIViewController = mainStoryboard.instantiateViewController(withIdentifier: "LeftVC")

//  Remove Left panel


  • Preview, when changing center panel from left/right panels

Change Center Panel (With custom transitions and durations)

  • Change Left, Right or Center Panel from any view controller

//  Specify the transition type

panel!.configs.centerPanelTransitionType = .transitionOption     // Transitions supported are mentioned in FAPanelTransitionType

//  Specify the transition duration

panel!.configs.centerPanelTransitionDuration = 0.60

//  Update the center panel


  • Transitions Preview
