Adds animated counting support to UILabel.

A label which can show number change animated in Swift, inspired by UICountingLabel.




To run the example project, clone the repo, and run pod install from the Example directory first.

EFCountingLabel is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'EFCountingLabel'

Swift Package Manager

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the Swift compiler.

Once you have your Swift package set up, adding EFCountingLabel as a dependency is as easy as adding it to the dependencies value of your Package.swift.

dependencies: [
    .package(url: "https://github.com/EFPrefix/EFCountingLabel.git", .upToNextMinor(from: "5.1.5"))


Simply initialize a EFCountingLabel the same way you set up a regular UILabel:

let myLabel = EFCountingLabel(frame: CGRect(x: 10, y: 10, width: 200, height: 40))

You can also add it to your xib or storyboard , just make sure you set the class and module to EFCountingLabel.


Set the format of your label. This will be filled with string (depending on how you format it) when it updates, you can provide a formatBlock, which permits greate control over how the text is formatted. If not provided, the default format will be "%d":

myLabel.setUpdateBlock { value, label in
    label.text = String(format: "%.2f%%", value)

Optionally, set the timing function. The default is EFTimingFunction.linear, which will not change speed until it reaches the end. Other options are described below in the Methods section.

myLabel.counter.timingFunction = EFTimingFunction.easeOut(easingRate: 3)

When you want the label to start counting, just call:

myLabel.countFrom(5, to: 100)

You can also specify the duration. The default is 2.0 seconds.

myLabel.countFrom(1, to: 10, withDuration: 3.0)

You can use common convinient methods for counting, such as:


Behind the scenes, these convinient methods use one base method, which has the following full signature:

myLabel.countFrom(startValue: CGFloat, to: CGFloat, withDuration: TimeInterval)

You can get current value of your label using currentValue method (works correctly in the process of animation too):

let currentValue: CGFloat = myLabel.counter.currentValue

Optionally, you can specify a completionBlock to perform an acton when the label has finished counting:

myLabel.completionBlock = { () in


There are currently four modes of counting.

  • EFTimingFunction.linear: Counts linearly from the start to the end;
  • EFTimingFunction.easeIn: Ease In starts out slow and speeds up counting as it gets to the end, stopping suddenly at the final value;
  • EFTimingFunction.easeOut: Ease Out starts out fast and slows down as it gets to the destination value;
  • EFTimingFunction.easeInOut: Ease In/Out starts out slow, speeds up towards the middle, and then slows down as it approaches the destination. It is a nice, smooth curve that looks great, and is the default method;
  • EFTimingFunction.easeInBounce;
  • EFTimingFunction.easeOutBounce.
