What is the UIKit equivalent of SwiftUI's Blur view. I'm aware of the visual effect view in UIKit, however we cannot adjust the blur radius in that.

SwiftUI Blur view:

struct Blur: View {
    var body: some View {
        VStack {
            Text("This is some text.")
                .padding()
            Text("This is some blurry text.")
                .blur(radius: 2.0)
        }
    }
}

Is this possible in UIKit?

use : blurEffectView.alpha = 0.2. Just set alpha of ```UIVisualEffectView``` – Raja Kishan May 24 '21 at 12:36
I tried that but the result is not great as you can't really notice the blur effect on lower alpha values. – unknown May 24 '21 at 13:21
@RajaKishan but you aren't supposed to change the alpha of `UIVisualEffectView` – aheze May 24 '21 at 15:37
Apple's docs explicitly say not to change the alpha of UIVisualEffectView – Duncan C May 24 '21 at 16:00
