IBAnimatable
Design and prototype 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 油Tube orMP4 on Github
Here is the design in Interface Builder (Storyboard).
With IBAnimatable , we can design a UI in an Interface Builder like Sketch, and prototype animations in a Swift playground like Framer Studio. 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 design UI. However, Sketch can't design interaction, navigation, transition and animation, we may need another tool like Framer Studio 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 minimise 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 like.
- Designer friendly - Sketch style setting panel on Attributes Inspector to lower the learning curve for using Interface Builder.
- Animation desigin support in Swift playground - Similar to Framer Studio, we can prototype animations in Swift playground to save time for runing on 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 and IBAnimatable also adds unwind segues to navigate back or dismiss scene without any code. More transitions will be added soon.
- 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 .
Use cases
- Prototyping - Create interactive proptotypes to validate ideas quickly.
- Redesigning in Interface Builder - Redesign UI from Sketch and animation from Framer Studio without writing any code.
- Making custom UI elements - Use IBAnimatable protocols to make custom UI elements. e.g. Buttons with a default color palette.
How to run the example App
The easy way to learn and understand how powerful of IBAnimatable is to run the example App and play around the settings in Interface Builder. Just few steps we can run the App as below:
1) Clone the repository
$ git clone https://github.com/JakeLin/IBAnimatable.git
2) Open the workspace in Xcode
$ cd IBAnimatable $ open "IBAnimatable.xcworkspace"
3) Compile and run the app in 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 few steps as below:
- Open a storyboard or Xib file.
- Drag and drop a UIKit element eg. UIView to a ViewController.
- In Identity Inspector, connect the UI element to Animatable custom UI class eg. AnimatableView , you can find all Animatable classes inAPIs section.
- 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 playgournd. There are three sample pages to demostrate how to design animation in Swift playground. You can find them in IBAnimatable.playground . Firstly, select 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 withouth single line of code, but IBAnimatable also provides APIs to let us fully control the UI and animations. IBAnimatable provides simple APIs like pop() . We can simplly call them in one line.
view.pop() // pop animation for the view view.squeezeFadeInLeft() // 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 customise the animation. What we need to do is to set the properties and call animate() method to start the animation.
// Setup the animation view.animationType = "SqueezeInLeft" view.delay = 0.5 view.damping = 0.5 view.velocity = 2 view.force = 1 // Start the animation view.animate()
You can play around with all animations with different properties in the Swift playground Page - Animation Properties
Chaining animations
Sometimes, we need to run another animation after the previous one. With IBAnimatble , we can easily chain animations together to provide a sleek user experience.
// Simplly put the next animation within `{}` closure as below. It is an example to pop the view after squeeze in from the top. view.squeezeInDown{ view.pop() } // Heaps of animations have been chained togehter, it is the source code of animated Gif in "Animate in Swift playground" section view.squeezeInDown{ view.pop { view.shake{ view.squeeze{ view.wobble{ view.flipX { view.flash{ view.flipY { view.fadeOutDown() } } } } } } } } How to install

Animatable UI elements
The easiest way to use IBAnimatable is to drag and drop UIKit elements and connect with Animatable UI elements in Identity Inspector. Here are the supported Animatable UI elements to map UIKit elements.
| UIKit elements | Animatable UI elements | Remark |
| UIView | AnimatableView | |
| UIBarButtonItem | AnimatableBarButtonItem | |
| UIButton | AnimatableButton | |
| UIButton | AnimatableCheckBox | Connect UIButton as AnimatableCheckBox to make CheckBox control |

Designable protocols
IBAnimatable provides a set of Designable protocols as below. Because of the power of protocol oriented programming in Swift, we don't even have to use Animatable default UI elements eg. AnimatableView to unlocked the power of IBAnimatable . We can conform to IBAnimatable protocols to use the default implementation in protocol extension to create other custom UI elements.
BarButtonItemDesignable
