Remove BlurView in swift

It's hard to know exactly what is going on in your code, as you've clearly posted a cut up version (the last 4 lines are part of a method somewhere, presumably).

You could do something like this to remove all UIVisualEffectView subviews from your blurView:

for subview in blurView.subviews {
    if subview is UIVisualEffectView {
        subview.removeFromSuperview()
    }
}
