A simple view for building card like interface like Tinder and Potluck. ZLSwipeableViewSwift is based on ZLSwipeableView.


Custom Animation


Custom Swipe


Custom Direction







You can install ZLSwipeableViewSwift through CocoaPods adding the following to your Podfile:

pod 'ZLSwipeableViewSwift'

Then import it using:

import ZLSwipeableViewSwift


You can install ZLSwipeableViewSwift through Carthage by adding github "zhxnlai/ZLSwipeableViewSwift" to your Cartfile

Swift Package Manager

You can install ZLSwipeableViewSwift through Swift Package Manager by adding it to the dependencies value of your Package.swift.

dependencies: [
    .package(url: "", .branchItem("master"))


Check out the demo app for an example. It contains the following demos: Default, Custom Animation, Custom Swipe, Allowed Direction, History, Previous View, Should Swipe and Always Swipe.


ZLSwipeableView can be added to storyboard or instantiated programmatically:

var swipeableView = ZLSwipeableView(frame: CGRect(x: 0, y: 0, width: 300, height: 500))

Adding Views

ZLSwipeableView supports both adding views to the front and to the back.

public var numberOfActiveView = UInt(4)
public var nextView: (() -> UIView?)?
public var previousView: (() -> UIView?)?

Adding views to the back

nextView, a closure that returns an UIView, works with loadViews and numberOfActiveView. It acts as the data source. After defining it, ZLSwipeableView will call loadViews which will invoke nextView numberOfActiveView times and insert them in the back. loadViews will also be called each time a view is swiped.

public func loadViews()
// Usage:
swipeableView.numberOfActiveView = 3
swipeableView.nextView = {
  return UIView()
swipeableView.loadViews() // optional, automatically call after nextView is set

Adding views to the front

previousView works with rewind, which inserts a view in the front and positions it at the center with animation. Note that rewind calls previousView only when history is empty, otherwise it returns the most recently swiped view. Please try out the Previous View example for more information.

public func rewind()
// Usage:
swipeableView.previousView = {
  return UIView()

Interface Builder

If you need to work with Interface Builder, the demo app includes examples of both creating views programmatically and loading views from Xib files that use Auto Layout.

Removing Views

Swiping programmatically

The user can swipe views in the allowed directions. This can also happen programmatically.

You can swipe the top view programmatically in one of the predefined directions or with point and direction in the view's coordinate.

public func swipeTopView(inDirection direction: Direction)
// Usage:
swipeableView.swipeTopView(inDirection: .Left)
swipeableView.swipeTopView(inDirection: .Up)
swipeableView.swipeTopView(inDirection: .Right)
swipeableView.swipeTopView(inDirection: .Down)

public func swipeTopView(fromPoint location: CGPoint, inDirection directionVector: CGVector)
// Usage:
swipeableView.swipeTopView(fromPoint: CGPoint(x: 100, y: 30), inDirection: CGVector(dx: 100, dy: -800))


ZLSwipeableView keeps a history of swiped views. They can be retrieved by calling rewind.

public var history = [UIView]()
public var numberOfHistoryItem = UInt(10)

public func rewind()

Removing all views

To discard all views and reload programmatically (discarded views cannot by rewinded):



Here is a list of callbacks you can listen to:

swipeableView.didStart = {view, location in
    print("Did start swiping view at location: \(location)")
swipeableView.swiping = {view, location, translation in
    print("Swiping at view location: \(location) translation: \(translation)")
swipeableView.didEnd = {view, location in
    print("Did end swiping view at location: \(location)")
swipeableView.didSwipe = {view, direction, vector in
    print("Did swipe view in direction: \(direction), vector: \(vector)")
swipeableView.didCancel = {view in
    print("Did cancel swiping view")


Here is a list of customizable behaviors:

public var animateView = ZLSwipeableView.defaultAnimateViewHandler()
public var interpretDirection = ZLSwipeableView.defaultInterpretDirectionHandler()
public var shouldSwipeView = ZLSwipeableView.defaultShouldSwipeViewHandler()
public var angle = CGFloat(1.0)
public var minTranslationInPercent = CGFloat(0.25)
public var minVelocityInPointPerSecond = CGFloat(750)
public var allowedDirection = Direction.Horizontal


You can change how the direction gets interpreted by overriding the interpretDirection property. Take a look at the Custom Swipe example for details.


You can create custom animation by overriding the animateView property. Take a look at the Custom Animation example for details.

Should Swipe

shouldSwipeView, minTranslationInPercent and minVelocityInPointPerSecond determines whether a view should be swiped or not. Please see the Should Swipe example for details.


The allowedDirection property limits the directions in which the user is allowed to swipe. Please see the Custom Direction example for details.

swipeableView.allowedDirection = .Left | .Up
swipeableView.allowedDirection = .All


You can change the rotation of the swipe views with the 'angle' property


public func topView() -> UIView?

public func activeViews() -> [UIView]


  • iOS 7 or higher.
