IBAnimatable: A Swift repository from DanielAsher

Design and prototype customized UI, interaction, navigation, transition and animation for App Store ready Apps in Interface Builder with IBAnimatable.

The app was made in Interface Builder with IBAnimatable without a single line of code. Due to the size of the GIF file on Dribbble, it only demonstrates a subset of features. We can also find the full HD version on YouTube or MP4 on Github

Key features

✅ 100% compatible with UIKit. All IBAnimatable APIs are extensions of UIKit. No pollutions to UIKit's APIs.
✅ 100% compatible with Auto Layout and Size Classes. No custom layout system.
✅ User interface design and preview in IB: corner radius, border, mask, shadow, gradient colors, tint color, blur effect etc.
✅ Animation design in IB: slide in/out, fade in/out, zoom in/out, flip, pop, shake, rotate, move etc.
✅ Transition design in IB: fade, slide, flip, cube, portal, fold, explosion etc.
✅ Interactive gesture design in IB: pan, screen edge pan, pinch etc.
✅ Presentation design in IB: flip, cover, zoom, dropdown etc.
✅ Activity indicator design in IB: ball beat, ball rotate, cube transition, Pacman etc.

Here is the full design in a Storyboard in Interface Builder.

With IBAnimatable, we can design a UI in Interface Builder like what we can do in Sketch, and prototype animations in a Swift playground like what we can do in Framer. Also, we can use the output of the design directly in the production ready App.

As a designer, we love Sketch, which is a simple but yet super powerful tool to create UI. However, Sketch can't design interaction, navigation, transition and animation, and we may need another tool like Framer to design some of them. Moreover, to make an App Store ready App, we need to use Xcode and Interface Builder to implement the UI and animations. To speed up the process and minimize the waste, we create IBAnimatable to make Interface Builder designable and animatable.

Features

From prototype to shippable App Store ready App - What you design in Interface Builder is what the App exactly looks. More details can be found in this talk Prototype and Design App Store ready Apps in Interface Builder (/dev/world/2016)
Designer-friendly - Sketch style configuration panel on Attributes inspector () to lower the learning curve for using Interface Builder.
Animation design support in Swift playground - Similar to Framer, we can prototype animations in Swift playground to save time for running on a simulator or actual iOS devices.
Built-in Auto Layout support - We can use Auto Layout and Size Classes with IBAnimatable to support orientations and multiple iOS devices.
Navigation and transition support - We can use default navigation pattern in the App. IBAnimatable also has custom transition animators and segues to support transition animations and gesture interactions.
Protocol-oriented programming - IBAnimatable uses a protocol-oriented programming paradigm. With Swift protocol extension, it is easy to support more designable or animatable features. We can even use these protocol extensions to create other custom UI elements instead of using the default ones from IBAnimatable. More details can be found in this talk Prototype and Design App Store ready Apps in Interface Builder (/dev/world/2016) - Part 2: Protocol oriented programming

Use cases

Prototyping - Create interactive prototypes to validate ideas quickly.
Redesigning in Interface Builder - Redesign the UI from Sketch and animations from Framer without writing any code.
Making custom UI elements - Use IBAnimatable protocols to make custom UI elements. e.g. Buttons with a default color palette.

Documentations

How to run the example App

The easy way to learn and understand how powerful of IBAnimatableis to run the example App and play around the settings in Interface Builder. Just a few steps we can run the App as below, to see more features, we can tap on "Forget Password" button to unlock them. 😉

Clone the repository

$ git clone https://github.com/IBAnimatable/IBAnimatable.git

Open the workspace in Xcode

$ cd IBAnimatable
$ open IBAnimatable.xcworkspace

Compile and run the app on your simulator or iOS device

How to design in Interface Builder

To use IBAnimatable to design the UI and animations in Interface Builder, just follow a few steps as below:

Open a Storyboard or Xib file.
Drag and drop a UIKit element e.g. UIView to a UIViewController.
In Identity inspector (), configure the UI element to Animatable custom UI class e.g. AnimatableView, you can find all Animatable classes in APIs.md.
Configure the UI and animations in Attribute Inspector.

How to animate in Swift playground

We can configure the animation settings in Attribute inspector. However, Interface Builder doesn't support previewing Animations, but we can still prototype animations in Swift playground. There are three sample pages to demonstrate how to design animation in Swift playground. You can find them in IBAnimatable.playground.

Open IBAnimatable.xcworkspace
Select IBAnimatable Framework scheme and build it with Command + b
Select IBAnimatable.playground, choose one page in Swift playground, then click on "Assistant editor" button to split the playground. After that, select "Timeline" on the top of right-hand side to preview the animation. We can use Xcode menu "Editor" -> "Execute" to re-run the playground.

How to animate programmatically

As you saw above, we can prototype an App fully in Interface Builder without a single line of code, but IBAnimatable also provides APIs to let us fully control the UI and animations. IBAnimatable provides simple promise-like APIs. We can easily call them in one line.

view.animate(.pop(repeatCount: 1)) // pop animation for the view
view.animate(.squeezeFade(way: .in, direction: .left)) // squeeze and fade in from left animation

You can play around with all these predefined animations in the Swift playground Page - Predefined Animations

Animation properties

There are some properties we can change to customize the animation. What we need to do is to pass the parameters to animate() method to start the animation.

view.animate(.squeeze(way: .in, direction: .left), duration: 1, damping: 1, velocity: 2, force: 1)

You can play around with all animations with different parameters in the Swift playground Page - Animation Properties

Chaining animations

Sometimes, we need to run more animation after the previous one. With IBAnimatable, we can easily use promise-like API to chain all animations together to provide a sleek user experience.

// We can chain the animations together, it is the source code of animated GIF in "Animate in Swift playground" section
view.animate(.squeezeFade(way: .in, direction: .down))
    .then(.pop(repeatCount: 1))
    .then(.shake(repeatCount: 1))
    .then(.squeeze(way: .in, direction: .down))
    .then(.wobble(repeatCount: 1))
    .then(.flip(along: .x))
    .then(.flip(along: .y))
    .then(.slideFade(way: .out, direction: .down))

Delaying animations

We can use delay method to delay the next animation.

view.animate(.squeeze(way: .in, direction: .left))
    .delay(0.5)
    .then(.shake(repeatCount: 3))

We can also delay the first animation.

view.delay(2)
    .then(.squeeze(way: .in, direction: .left))

Completion handler

We can add a completion handler/closure to execute when all animations are completed.

view.animate(.squeeze(way: .in, direction: .left))
    .completion { print("Animations finished!") }

How to install

Manually install

Copy and paste IBAnimatable folder in your Xcode project.

Swift package manager

Add .Package(url: "https://github.com/IBanimatable/IBanimatable.git", majorVersion: 5) to your Package.swift

CocoaPods

Add pod 'IBAnimatable' to your Podfile.

Carthage

Add github "IBanimatable/IBAnimatable" to your Cartfile.

Please Notice, there is a limitation of a built framework for @IBDesignable and @IBInspectable, that will impact on IBAnimatable when you use Carthage. There is a workaround to use Carthage or Swift package manager with IBAnimatable, please have a look at Carthage – no Animatable UI Classes appearing in Storyboard

As @DanielAsher mentioned

I use carthage update --use-submodules --no-build --no-use-binaries and manually add the both the framework project and the framework as an embedded dependency. This method is robust, and fine-grained, but perhaps not as easy as dragging the built framework into your project.

Git submodule

Add this repo as a submodule, and add the project file to your workspace. You can then link against IBAnimatable.framework for your application target.
