Can't stop animate.

[WCChimiiz]

I use

progress!.animate(fromAngle: 0, toAngle: 360, duration: 10) { completed in
            if completed {
                print("completed")
            } else {
                print("animation stopped, was interrupted")
            }
        }

Then I want to stop animate I try call

progress?.stopAnimation()

It's work. But a few moment in console print completed also.

How I fix it ?

Thank you.
