How to add visual effect blurs
In the process of being updated for Xcode 13.0
New in iOS 15
SwiftUI has a brilliantly simple equivalent to UIVisualEffectView, that combines ZStack, the background() modifier, and a range of built-in materials.
For example, this places some text over an image, applying a standard blur effect to the text:
ZStack {
Image("singapore")
Text("Visit Singapore")
.padding()
.background(.thinMaterial)
}

You can adjust the “thickness” of your material – how much of the background content shines through – by using one of several material types. From thinnest to thickest, they are:
.ultraThinMaterial.thinMaterial.regularMaterial.thickMaterial.ultraThickMaterial
If you’re using the secondary foreground color, SwiftUI automatically adjusts the text color so that it has a vibrant effect and can stand out from the background:
ZStack {
Image("singapore")
Text("Visit Singapore")
.foregroundColor(.secondary)
.padding()
.background(.ultraThinMaterial)
