ALProgressRing - is a library for displaying a circular progress ring.

It's easy to customize. You can adjust the gradient for the ring, line width, shadow, and more.

Also for this library, I added about 20 functions for animation, more details in the Animation section

If you liked this library, please do not forget to put a ★ star, it will help me in its development.

Swift Package Manager

The Swift Package Manager is a tool for managing the distribution of Swift code. It’s integrated with the Swift build system to automate the process of downloading, compiling, and linking dependencies.

To integrate ALProgressRing click File -> Swift Package -> Add Package Dependency and insert:


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

pod 'ALProgressRing'


If you prefer not to use either of the aforementioned dependency managers, you can integrate ALProgressRing into your project manually. Put Source/ALProgressRing folder in your Xcode project.


Quick Start

import ALProgressRing

class MyViewController: UIViewController {

    private lazy var progressRing = ALProgressRing()

    override func viewDidLoad() {

        // Setup layout
        progressRing.translatesAutoresizingMaskIntoConstraints = false
        progressRing.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
        progressRing.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true
      	// Make sure to set the view size
        progressRing.widthAnchor.constraint(equalToConstant: 180).isActive = true
        progressRing.heightAnchor.constraint(equalToConstant: 180).isActive = true
        progressRing.setProgress(0.8, animated: true)



You can customize the buttons, headers and indicators colors depending on their state.

/// Set track color
/// If you don't need a gradient, just set the same values for `startColor` and `endColor`
progressRing.startColor = .systemPink 
progressRing.endColor = .systemRed 

/// Set groove color
progressRing.endColor = .systemRed 


progressRing.startAngle = -.pi / 2 // The start angle of the ring to begin drawing.
progressRing.endAngle = 1.5 * .pi // The end angle of the ring to end drawing. 
progressRing.startGradientPoint = .init(x: 0.5, y: 0) // The starting poin of the gradient
progressRing.endGradientPoint = .init(x: 0.5, y: 1) // The ending position of the gradient.

// Sets the line width for progress ring and "groove" ring
progressRing.lineWidth = 10
// Or, if you need to separate these parameters, use
progressRing.ringWidth = 10 
progressRing.grooveWidth = 8 


progressRing.duration = 2 // Duration of the ring's fill animation.
progressRing.timingFunction = .easeOutExpo // Timing function of the ring's fill animation.

/// The following use of setProgress (_ value: Int, animated: Bool) 
/// will take into account the new parameters 
progressRing.setProgress(0.8, animated: true)

Let's take a look at the timingFunction parameter, it is of type ALTimingFunction, which contains the following types of animations:
