How to scale a view up or down
Updated for Xcode 12.5
SwiftUI’s scaleEffect() modifier lets us increase or decrease the size of a view freely.
For example, we could make a text view five times its regular size like this:
Text("Up we go")
.scaleEffect(5)
.frame(width: 300, height: 300)You can scale the X and Y dimensions independently if you want, allowing you to squash views like this:
Text("Up we go")
.scaleEffect(x: 1, y: 5)
.frame(width: 300, height: 300) If you want more control, you can specify an anchor for your scaling like this:
Text("Up we go")
.scaleEffect(2, anchor: .bottomTrailing)
.frame(width: 300, height: 300) That makes the text view twice its regular size, scaled from the bottom-right corner.
Tip: Scaling up a view won’t cause it to be redrawn at its new size, only stretched up or down. This means small text will look fuzzy, and small images might look pixellated or blurry.
