How to blur a view

Paul Hudson    @twostraws   

Fully updated for Xcode 11.4

The blur() modifier lets us apply a real-time Gaussian blur to our views, at a strength of our choosing.

For example, this creates a 300x300 profile picture, then adds a 20-point Gaussian blur:

Image("paul-hudson")
    .resizable()
    .frame(width: 300, height: 300)
    .blur(radius: 20)

You can blur anything you want, including text views:

Text("Welcome to my SwiftUI app")
    .blur(radius: 2)
