UIView.animate() issue

I have a code, where UI elements are changed after user interaction. I use UIView.animate() to refresh UI. The code is pretty simple:

UIView.animate(withDuration: 1.0) {
    self.fadeIn()
} completion: { _ in
    UIView.animate(withDuration: 1.0) {
        self.fadeOut()
    }
}

Very important point is that total animation duration from beginning to the end should be 2 seconds. But sometimes, there are no UI changes in fadeIn(), and UIView.animate() just get immediately to completion block. But in that option I want to have a delay for duration time (1 sec), and only after that get to completion block to fadeOut. How I can force animate with duration even if it's nothing to animate in animation block? Thanks in advance!

Maybe don't call fadeOut() in the completion block, and just make sure that it's called with one second delay after the fadeIn() is called?

UIView.animate(withDuration: 1.0) {
    self.fadeIn()
} 

UIView.animate(withDuration: 1.0, delay: 1.0) {
    self.fadeOut()
}
