Requirements

iOS 9.0+
Xcode 9.0+
Swift 5 (VisualEffectView 4.x), Swift 4 (VisualEffectView 3.x), Swift 3 (VisualEffectView 2.x), Swift 2 (VisualEffectView 1.x)

Usage

Add an instance of VisualEffectView to your view.

import VisualEffectView

let visualEffectView = VisualEffectView(frame: CGRect(x: 0, y: 0, width: 320, height: 480))

// Configure the view with tint color, blur radius, etc
visualEffectView.colorTint = .redColor()
visualEffectView.colorTintAlpha = 0.2
visualEffectView.blurRadius = 10
visualEffectView.scale = 1

addSubview(visualEffectView)

Depending on the desired effect, the effect may affect content layered behind the view or content added to the visual effect view’s contentView. After you add the visual effect view to the view hierarchy, add any subviews to the contentView property of the visual effect view. Do not add subviews directly to the visual effect view itself. Refer to the UIVisualEffectView for more info.

For more examples, take a look at the example project.

Customization

var colorTint: UIColor // tint color. default is nil
var colorTintAlpha: CGFloat // tint color alpha. default is 0
var blurRadius: CGFloat // blur radius. default is 0
var scale: CGFloat // scale factor. default is 1

If you want colorTintAlpha to be different from 0, make sure you always set it right after setting the colorTint or it may not be applied as expected. You also have to make sure you don’t set colorTintAlpha if colorTint is nil.
