A simple Pie view that can show all slices of a Pie 😊. Also,

You can use the Swift package manager to install PieKit.

.package(url: "https://github.com/MojtabaHs/PieKit", .upToNextMajor(from: "0.2.0"))

PieKitis FREE and open-source for individuals, and will remain that way forever.

You can easily set the color and progress:

pieView.fillColor = .red
pieView.progress = 0.3

And just set the duration (for timedPie) and it will animate the progress down to 0.

timedPieView.duration = 3

You can use the delegate method to access the progress changes when it is animating.

extension ViewController: TimedPieViewDelegate {

    func timedPie(_ pie: PieView, didChangeRemainingTime remainingTime: TimeInterval) {
        print(remainingTime)
    }
}

This method can cause a huge impact on performance. The called is responsible for preventing it from executing heavy instructions.
