UISwitch setOn(:, animated:) does not work as document

Question

As Apple\'s document write, UISwitch\'s function setOn(on: Bool, animated: Bool) does not send action. It works fine before iOS 10, but it will send ac

Answer 1

DispatchQueue.main.async {
    sender.setOn(flag, animated: animated)
}

it works for me in Xcode 8.

but call UISwitch.setOn(_:animated:) directly on main thread doesn't work.

Update

thanks to @codiction:

UISwitch.setOn(_:animated:) can be called direclty on main thread, but can't be called directly in UISwitch ValueChanged action on iOS 10.
