You can use a DownloadingProgressButton on Storyboards

func stateWasChanged(to newState: DownloadStates, sender: DownloadingProgressButton) {
    if newState == .pending {
        // MARK: perform some actions and inform button
        sender.downloadingStarted()
    }
}
// MARK: change downloading progress
button.downloadingProgressChanged(to: 0.2)

When this value reaches >= 1.0, then button is automatically animates to the end and takes done state.

To set or reset downloaded state:

button.downloadingSet()
button.downloadingReset()

To start animations programmatically:

button.startProgrammatically()
