How to control the blur radius of an UIImageView

Hi, I am working on my todolist app. In a page, I am using an image that is slightly blurred. In Sketch, I can control the blur radius of that image, but I am not sure how to do that in Swift. I have already tried the UIBlurEffect, but I cannot control the amount of blur.

let lightBlur = UIBlurEffect(style: UIBlurEffectStyle.Light)
let blurView = UIVisualEffectView(effect: lightBlur)
blurView.frame = imageForHeader.bounds
imageForHeader.addSubview(blurView)

Can someone tell me how to do that?

Hey, UIBlurEffect doesn't have a property for the blur radius, instead check out this:

Here you can find how to make a better blur effect where you could specify the blur radius
